Causes of oil pressure drop

The instrument panel has a light bulb that signals an emergency pressure of the engine in the engine. When it lights up this explicit fault sign. Tell what to do if the oil pressure lamp lights up and how to eliminate the malfunction.

The oil control light can light up for two different reasons: either low oil pressure, or low oil level. But what exactly means light bulb oil-littered on the dashboard, it will help to find out only the instruction manual. It will help us the fact that, as a rule, budget cars do not have an indicator of a low oil level, but only low oil pressure.

Insufficient oil pressure

If the oil lamp caught fire - this means insufficient oil pressure in the engine. As a rule, it lights up only for a few seconds and is not a big threat to the motor. For example, it can light up with a strong roll of the machine in turn or with a cold start in winter.

If the low oil pressure light lights up due to low oil level, this level is usually already critical. First of all, when the oil pressure light lights up - check the presence of engine oil. If the oil level is below the norm, then it is the reason for the lighting of this lamp. This problem is solved simply - you need to add oil to the desired level. If the light bulb went out - we rejoice, and do not forget to pull the oil on time, otherwise it can turn into serious problems.

If the oil pressure light is burning, but with the level of oil on the dipstick everything is in order, then another reason why the indicator can light up is a failed oil pump. It does not work on sufficient oil circulation in the engine lubrication system.

In any case, if the oil pressure lamp or low oil is caught fire, the car must be stopped immediately by moving onto the road or in a safer place, and drown. Why do you need to immediately stop? Because if the oil in the motor dried significantly, the latter can stop and break from the prospect of very expensive repairs. Do not forget that the oil is very important to maintain the engine performance. Without oil, the engine will fail very quickly - sometimes in a few minutes of work.

Also, this situation occurs when the oil in the engine is changed to the new one. After the first launch, the oil pressure light can light up. If good quality oil, it should go out in 10-20 seconds. If it does not go out - the reason for defective or non-working oil filter. It needs to be replaced with a new quality.

Oil pressure sensor malfunction

The pressure of the oil at idle (approximately 800 - 900 rpm) should not be less than 0.5 kgf / cm2. Sensors for measuring an emergency oil pressure are with a different triggering range: from 0.4 to 0.8 kgf / cm2. If the car is installed on the car with a quotation value of 0.7 kgf / cm2, even at 0.6 kgf / cm2 it will turn on the control lamp signaling about the emergency pressure of the oil in the motor.
To understand, faults in lightning light bulb oil pressure sensor or not, you need to increase the crankshaft speed up to 1000 revolutions per minute at idle. If the bulb goes out, then the engine pressure in the engine is normal. If not, you need to contact the specialists who measure oil pressure to a manometer by connecting it instead of the sensor.
From false transitions of the sensor helps cleaning. It is necessary to unscrew it and thoroughly clean all the oil channels, because the reason for the false triggering of the sensor may be clogged.

If the oil level is normal and the sensor is correct

First of all, you need to check the oil dipstick and make sure there was no longer the oil level after the last check? Does not smell of oil probe with gasoline? Perhaps the engine gets gasoline or Tosol. Check for gasoline in oil easily, you need to omit the dipstick to the water and see whether gasoline divorces will remain. If so, then you need to contact the car service, you may have to repair the engine.
If the engine malfunctions, which was the sunbathing of oil pressure lights - it is easy to notice. Motor malfunctions are accompanied by power loss, increasing fuel consumption, from the exhaust pipe is black or blue smoke.

If the oil level is normal, then it is not necessary to fear the long-term display of the low oil pressure, for example, with a cold start. In winter, at low temperatures, it is an absolutely normal effect.
After a night parking, oil flows from all highways and thick. The pump needs a certain time to fill the highways and create the necessary pressure. The oil to the indigenous and connecting rod cervix arrives earlier than to the pressure sensor, so the wear of the engine parts is excluded. If the oil pressure lamp does not go out about 3 seconds - this is not dangerous.

What can be done yourself

Measurement of oil pressure
The low pressure problem of the oil strongly complicates the relationship of lubrication consumption and lowering the level with a general pressure indicator in the system. In this case, a number of faults can be eliminated independently.

In case of detection of leaks, the problem is quite easy to localize and decide. For example, the leakage of oil from under the oil filter is eliminated by its suspender or replacement. A similar way is solved and the problem with the oil pressure sensor through which the lubricant flows. The sensor is delayed or simply changes to a new one.
As for the leaks of the glands, in this case it will take the presence of time, tools and skills. At the same time, it is possible to replace the front or rear crankshaft gland in his own hands in the garage with the observation pit.

Leather oils from under the valve cover or in the pallet region can be eliminated by tightening fasteners, replacing rubber sealing gaskets, with special sealants for the engine. Violation of the geometry of the connected planes or damage to the valve / pallet lid will indicate the need to replace such parts.

If the coolant falls into the engine oil, then you can remove the GBC itself and replace the blocking of the block head, while observing all the recommendations regarding the removal and subsequent tightness of the cylinder head. Additional checking of the bullshit planes will indicate whether it is necessary to make a blocking of the head of the block. When detecting cracks of the cylinder or head, repair is also possible.
As for the oil pump, this element in case of wear is better immediately replaced with a new one. It is also not recommended to clean the oil worker, that is, the item is completely changing.
In the event that the problem in the lubrication system is not so obvious, while repairing the car is independently, then at the very beginning it is necessary to measure the oil pressure in the engine.
To solve the problem, as well as taking into account the exact idea of \u200b\u200bwhat the oil pressure is measured in the engine and how it is done, you need to prepare additional equipment in advance. Note, there is a ready-made device for measuring the oil pressure in the engine.

Alternatively, the oil pressure meter is universal "measure". Such a device is quite affordable by price, it has everything you need. You can also make a similar device with your own hands. This requires a suitable oil-resistant hose, pressure gauge and adapters.

To measure, the finished or self-made device is connected instead of the oil pressure sensor, after which the pressure testimony is evaluated on the pressure gauge. Please note the usual hoses to use during self-making cannot be. The fact is that the oil quickly corps rubber, after which the detached parts can get into the oil system.

RESULTS

Pressure in the lubrication system may fall for many reasons:
- quality of oil or loss of its properties;
-the seals, gaskets, seals;
-Mollo "Davit" from the engine (grows pressure due to violations of the crankcase ventilation system);
- Maslonasososososososos, other breakdowns;
-Syl unit can be very worn, etc.

In some cases, drivers resort to the use of the additive to increase the oil pressure in the engine. For example, XADO Revitalizant. According to the manufacturers, such an antidymnaya additive with revitalizer reduces oil consumption, allows the lubricant to maintain the necessary viscosity when heated to high temperatures, restores damaged neck and crankshaft liners, etc.

As practice shows, an effective solution of the problem of low pressure additives cannot be considered, but as a temporary measure for old worn motors, the specified method may approach. I would also like to pay attention to the fact that the blink of the oil pressure light bulb does not always indicate problems with DVS and its systems.
Rarely, but it happens that there are problems on the electrics. For this reason, one should not exclude the likelihood of damage to the electrical elements, contacts, pressure sensor or the wiring itself.

Finally, add that avoiding many problems with the oil system and the engine helps the use of only recommended oil. It is also necessary to pick up lubricant taking into account the individual features of operation. No less attention is also deserved and the correct selection of viscosity index for the season (summer or winter oil)

Motor oil and filters need to be changed correctly and do it strictly according to the regulations, since the increase in the interservice interval leads to strong contamination of the lubrication system. Disintegration products and other deposits in this case are actively settled on the surfaces of the parts and walls of the channels, clog filters, an oil grid. Olonasos in such conditions may not provide the desired pressure, oil starvation occurs and significantly increases the wear of the motor.

Gold 1 million box at the 2011 Conder 2012

The manufacturer of GETRAG transmissions has created a joint venture with FOMOCO (Ford Motor Company) for the release of preselective gearboxes with two clutches. As well as DSG, they are two species:

with wet clutch WD (Wet Dual Clutch)
with DD DD Clutch (Dry Dual Clutch)

The design gearbox is identical to the DSG box with a wet clutch, the difference in software and the number of gear: DSG is maximally 7, and PowerShift - 6. For VAG, the mechanical part and software developed a Borg Warner company, and for Ford - Getrag and LUK . DSG is tougher, with a light jerk at start and well-tangible braking engine for a dumping gas. In PowerShift, the switch is softer, almost like a classic hydromechanical machine, but it is possible to effectively slow down the motor only in manual mode. Specialized club service DCT + performs diagnostics and repair of the box of Ford Focus 3 in Moscow with a guarantee.

Decoding designations (getrag)

DCL - longitudinal location of the PPC (L)

DCT - transverse location of the gearbox (T)

6DCT / 7DCT - 6/7 speeds

250/450/750 - Transmitted torque in n / m

For DCT with low torque (up to 300 nm), DD enclosure boxes are installed. For more powerful cars, "wet" clutch WD (450/470, etc.).

For Ford Focus 3, 3 types of transmissions are installed: MCPP, Ford Focus 3 automatic transmission, robot (dry 6DCT250 and wet 6DCT450 for diesel versions).

6F35 assembled

Hylobal 6F35

6 Speed \u200b\u200bautomatic transmission 6F30 / F35 / 6F50 / 6F15 from Ford - Joint with General Motors. In terms of mechanical part, automatic transmission with hydrotransformer 6F35 is an almost complete analogue of transmissions at the GM 6T40 / 6T45 transmissions, parts for the production of which are as low as possible to reduce the cost of development and differ in the electrical part, filters, pallets and outputs for various layouts and other small nuances .

This CAT model (6F35) is installed on almost the entire Ford model range (C-Max, EcoSport, Escape, Fiesta, Focus, Galaxy, Kuga, Mondeo, S-Max). If you take a specifically Focus, then the model with a 1.5 liter engine is 6F35, with a 1.0 liter engine goes 6F15.

Transmission is made at the US plants (Sterling Heights, Michigan, also Sharonville, Ohio) and in China. In general, the 6F family - on modern standards reliable and comfortable automatic transmission with 6 transmissions. They differ from the previous generations of American 4-speed automata in that it is somewhat earlier that preventive repair and cleaning of the system are required, and, as most of the modern economy automatic transmission, does not like aggressive ride.

Unlike GM-CIA Series 6T, the 6F series is configured to a less dynamic and more careful program of operation of automatic transmission. Ford regularly updates the firmware of the ACAP ECU, mostly all updates are aimed at cutting the drive and preserve the hydroblock and the torque converter.

Since 2012, significant changes in the hydraulic and electrical part have been made to the design, as well as consumables. For example, the filter was completely made of plastic, but retaining the double membrane from the felt. Change better more often.

Disposable filter and change it with each oil change. The period of oil replacement strongly depends on operating modes. With a calm ride on the highway, the first oil change may be needed approximately after 80-100 thousand km of run. But after long loads near the limiting torque (at low speeds), oil replacement can be required in urban passages after 20 thousand km. In general, as usual, on average every period of 60 thousand km. It is also necessary to preventively repair the hydrotransformer, without waiting for its failure (approximately 150 thousand km). The more aggressive driving, the faster the friction is eaten.

The entire series of 6f capricious to the level of oil does not have the probe and the oil level is checked by overflow plug. And how all modern front-wheel drive boxes do not like loads during cold oil. Winter heating gearbox before driving is strictly recommended.

Typical repair 6F35 / 6F15

In the averaged model repair of the box, the Ford Focus 3 machine with automatic transmission 6F35 / 6F15 includes:

mandatory repair of the hydrotransformer
repair / cleaning of the hydroblocation with the replacement of rings and seals
set of friction and steel disks
replacing damaged parts in the mechanical part
consumables

6DCT250 device (DPS6)

The PowerShift 6DCT250 is a product of the newest sections of a gearbox with two clutches from getrag. They combine the convenience of the usual automatic transmission with characteristics and high level of efficiency of mechanical gearboxes. All double-grip GETRAG gearboxes operate without interrupting power flow and achieve CO2 emissions reduction. 4-8%. Compared to the classic DPS6 hydrotransformer automatic transmissions with dry double adhesion and electromechanical drive, it reaches a decrease in fuel consumption to 20% (in comparison with the usual automaton, and not by car in general).

As usual, getRag declares that in 6DCT250 oil is flooded for the entire service life. But it is still worth changing the problems ahead of time.

The 6-step transmission 6DCT250 was designed to be installed in the front-wheel-transverse layout in the compact car segment and is designed for a torque up to 280 nm. It can be equipped with separately with the full drive system, as well as the START- / STOP function without modifying the equipment. Also, DPS6 can be used in a hybrid drive (combining with an electric motor).

Comparison of the effectiveness of mechanical gearbox and 6DCT250

Main features 6DCT250:

Uses dry clutch, which is not cooled in oil. Increases efficiency.
It is filled with oil and sealed for life (the estimated service life is 10 years or 240,000 km), does not require periodic maintenance.
It has a dry weight of 73 kg
Faster gears and lower losses when transmitting torque.
Electro-mechanical drives eliminate the need for hydraulic lines.
Dry clutch does not require cooling
The complexity of the design can lead to problems and difficulties in repair

It is worth noting that manufacturers switches with a gearbox with dry coupling on the gearbox with wet clutches due to higher reliability and thermal constraints (even when using a low torque, which is a dry clutch area).

What does PowerShift 6DCT250 consist of:

As mentioned earlier, the DPS6 mechanically consists of 2 mechanical boxes that interact with the use of electrical equipment and electronics.

Double clutches and double entrance shafts

There are 2 input shafts, one of which is hollow (blue), and the other solid (yellow) and sits coaxially inside the hollow shaft.
Internal shaft (yellow) has fixed gears for gear 1, 3 and 5; While the outer shaft (blue) has fixed gears for 2, 4, 6 and vice versa. Please note that this shaft has only 2 mechanisms, each of which is used for two gears.
Each of these shafts is connected to the clutch through the slots outside the shaft.
This layout provides compact packaging of both couplings.
Unlike other couplings visible in manual gearboxes, in the normal state of resting the clutch is held with springs (i.e. does not transmit a torque) and must be powered for closing and retained with a closed holding current applied to the drive,
The transmitting electronics ensures that only one coupling will be closed at any time.

Output shafts

The gearbox has two output shafts (shown blue). Contrary to initial considerations, they do not carry transmissions corresponding to the input shafts. Instead, the gears that they carry are determined by the order of the selector forks.
Transmission on output shafts are not fixed, but are free. Like a manual gearbox, they are equipped with synchronizers to match the speeds and blocking gear.
Transmissions 1, 3.4, 5, 6 and reverse are equipped with a single synchronizer, and transmission 2 - double synchronization.
The second gear is connected to the rear gear on the same shaft (although both of them can rotate freely, they do it together).
Please note that orange return transmissions on both output shafts are directly related to each other. However, they do not interact with either yellow or with blue input shafts.
As a result, the output shafts and input shafts are not in the same plane - instead, they are located in a triangular formation.

Differential

Both outlet shaft transmit torque through the output gear on the total differential shaft (green).
This differential is not in the same plane as the output shafts, it is again shifted - 4 shafts are located in the form of a parallelogram.
The differential serves as the same purpose as the car equipped with mechanics - it allows you to rotate to each of the slave wheels at different speeds (for example, when turning).

Sleeves with synchronizer and selector plug

When discussing the output shafts, it was mentioned that none of the gears were attached to the shafts, and instead freely rotates.
There are 4 synchronizer (and appropriate assemblies) that allow these freely rotating gears to match the speed of the output shaft and block the gears. 3 of these bushings are used to engage between two gears (at different times), and 1 sleeve is used only for one gear.
Each of these synchronizer sleeves has a corresponding switching plug, which can move the sleeve to any side (to fix the gear) or in the middle (to unlock the gear).

Up to this point, the components that were considered are all familiar, as they are very reminded by mechanical gearboxes - rather, two Transmissions, since we have two clips, two input shafts and two output shaft. Only with differentials both of these units are combined at one output. Next, the components that are just the entire DCT PowerShift 6DCT250 are considered.

Shift actuators (actuators)

At the moment, we need to focus on two electric motors present in TCM, as they provide a rotational yield from TCM to activate the selector fork.
The engines have a dc design. They have built-in Hall sensors to determine the position of the rotor and counting the number of rotations passed.
Through the system of cylindrical gears, these rotating selector drums are underway at a certain angle (the stroke range for these drums is 200 - 290 degrees).
The side switches have a slot cut into them. The selector plug has a tongue that is in this nest.
The slot is located at an angle to the ends of the stroke, so that when the selector lever rotates, the tongue is forcibly perpendicular to the direction of rotation (that is, parallel to the axis of the selector drum). If it is confused to understand, imagine how the screw converts the rotational movement of the screwdriver into direct movement.
Thereby rotational motion created by electric motors can be transformed into move Fork selector back and forth . This allows the selector forkam to move the bushings of the synchronizer forward or back to lock and unlock certain gears.
For comparison, in the mechanical transmission gearbox, the selector fork is controlled manually using the gear shift levers.

Clutch drives

Like a switching, the clutch drive converts the movement of the electric motor into the lateral movement.
And the brushless DC motor is again used.
As mentioned earlier, the adhesion is retained by open-pressure spring by default and does not transmit torque.
To close the coupling, the engine rotates a worm gear that pushes the clutch drive.
To keep the clutch closed, the holding current is applied to the motor.
The following 2 animated images are a representative idea of \u200b\u200bhow each of the couplings are triggered. In the DSG principle the same.

Transmission Control Unit (TCM)

TCM 6DCT250 control unit

The image for the actuators of the shift is shifted by a pink item described as TCM. Slightly higher in the picture, which has input connectors from ECU. The side opposite to this has 2 engines that we have seen earlier.

TCM collects input signals from different sensors, evaluates the input and controls the drives, respectively.

The inputs used by TCM include:

Transmission range (P / R / N / D / S / L, etc.)
Car speed
Engine Rotation Frequency and Engine Torque
Position of throttle valve
Engine temperature
Ambient temperature (to determine how viscous oil is for cold launches)
The angle of rotation of the steering wheel (to avoid overloads or lowering when turning)
Bog inlets
The speed of the input shaft (for both input shafts)
Relationship (inclination) of the car from the body control module (BCM)

TCM controls the engines of the actuators using control with open contour to ensure adaptive control. This allows TCM to identify and adapt to the following:

Clutch engagement points (F1 fans will hear about the "point of the coupling bite")
Clutch friction coefficient
Position of each synchronizer node

Information for the above is stored in non-volatile RAM in TCM. This is what constitutes studied management models for a specific gearbox.

Sensors

There are several sensors that collect and provide TCM information, both from DCT and another place in the vehicle. Those related to the DCT itself:

Input shaft speed sensor (ISS sensor) - magneto-resistive sensor - one at the input shaft
Output Speed \u200b\u200bSensor (OSS Sensor) - Again, a magneto-resistive sensor - one sensor attached to differential
Transmission range sensor (TR sensor) - To determine the position of the selector lever and transform it into the PWM signal

PowerShift DPS6

Sport (S) and SELECTSHIFT (+/-)

Sport (s) mode allows the engine to rise above before switching to higher transmission.
This allows you to resolve the driver requests to switch to higher and lower transmissions using the +/- button.
These are only "queries", because TCM will evaluate this in relation to other inputs before switching gear - for example, it prevents switching to higher revs to avoid cut-off

Parking mode (P)

Parking mode

At the output shaft, the parking lot is fixed to the output shaft does not rotate.
The latch (pin) is horrified to ensure that it does not jump, if not disconnected.
Both couplings are not powered, so both they automatically open.
The shift actors block gears 1 and R - since the removal of the car from P will lead to the choice of one of these gears.
The user's manual also recommends installing the parking brake (manual brake) to ensure that this mechanism does not remove the entire load on the car (for example, on the slope).

Help mode when starting with slope

This feature is not an integral part of the 6DCT250, it also uses the brake system.
When the car is in a stopped state on a slope exceeding 3 degrees, help is activated.
The brake system is under pressure to hold the car until the sufficient torque is installed to move the vehicle. This may take 2-3 seconds.
This allows the driver to move the right leg from the brake to the gas pedal, while not rolling.

Neutral mode (N)

Clutches will be disconnected when using brakes.
It increases fuel savings, improves downward shutdown and improves clutch reliability.

Warning modes

If the clutch temperature is increased, warnings are generated to instruct the driver to stop on the vehicle until the clutch cools. The driver can also speed up the vehicle movement to cool the adhesion through the airflow (clutch can overheat when stopping and movement).
To reduce the heating of the coupling, the clutch will be involved faster than usual, and the engine torque decreases.
If the clutch temperature exceeds 300 degrees Celsius, couplings are disconnected.
If one of the engines of the clutch drive fails, then the transmission adapts to this using only gears on another coupling.
If speed sensors do not work on the input shaft, the gears on this shaft are blocked.
If the TCM itself or TR sensor (transmission range) does not work, both couplings are disconnected, and the vehicle cannot be controlled.
These failure modes will cause MIL / CEL (Motor Indicator / Indicator Indicator).

Typical problems 6DCT250.

Basically, problems are with a clutch, TCM block, switching forks and, also encountered, problems with the mechanical part of the checkpoint (see examples of work). The primary shaft seal is flowing.

Consider the main TCM connected blocks:

Twinks box when switching with 1st to 2nd. You need to update the software (firmware) of the TCM control unit.
During operation on the dashboard, the ESP lamp lights up and "Help Lifting Harness is inaccessible" appears.
Transmission disappears (optional all), the crawling mode is turned off

When installing a new robot control unit (TCM), you must register it (VIN, Calibration). We provide such a service too.

Tips for the correct operation of 6DCT250 from getrag

Before putting a car on "P" the driver must keep the brake pedal, raise the handbrake (parking brake), and only after that you can translate the scene to "P".
In the "R" modes, "D" and "S" can not be allowed for long operation of the engine when the brake pedal is pressed. In the position of the selector "D" and when the brake pedal is pressed, the coupling of the Powershift robot DPS6 6DCT250 is completely not blocked and slides slightly, so after a while local overheating of the node is possible. The company's specialists advised advised not to stand so longer than two or three minutes and translate the selector lever to "n" or "p".
Towing a car in "N" mode is allowed to 60 km / h.

Automatic PowerShift Transmission Ford is a preselective box with two clutches and a dual clutch. One of the features of this gearbox is the maximum smooth gear shifts that occur without interruption.

To the advantages of automatic gearboxes PowerShift. You can include a decrease in fuel consumption and improved car dynamics.

PowerShift Ford box - work principle

The design of this gearbox is an unit from dual parallel mechanical transmissions that function independently from each other. During movement, one part of the coupling includes even programs, and the other is responsible for the inclusion of odd steps. Thereby it is possible to avoid breaking power, which increases the safety of the car's operation with an automatic transmission. It has been established that, thanks to the use of automatic transmission Powershift, it is possible to reduce fuel consumption by 8%.

Transmission Power Shift Scheme

Which cars are installed PowerShift

This modification of preselective gearboxes is installed on the car brand car. PowerShift constructively refers to the gearboxes with wet clutch, as well as dry. This has a positive effect on the reliability and integralness of the transmission. At the same time, it is necessary to remember the mandatory regular change of oil (regarding wet boxes). In the event that the car owner neglects oil replacement procedure, problems with cooling and lubrication of a large number of movable elements may occur.

PowerShift gearbox is compact and installed on various cars

Thanks to its compact size, the automatic transmission of PowerShift can be installed with the same success on both a powerful Mondeo sedan and for compact cars Ford Focus. The automatic transmission can be used with the longitudinal and transverse location of the engine. This makes it possible to significantly expand the number of models of Ford and Volvo cars, which establishes this modification of the transmission.

Auto PowerShift Management

PowerShift Ford transmission control is performed completely using electronics. Built-in automatic systems monitor oil pressure, its temperature and speed of rotation of the internal shafts and couplings. Computer brain (mechatronics) correlates engine speed and vehicle speed. Electronics decides to change the gear and performs it as quickly as possible. Changing the steps takes place in the fraction of a second and completely imperceptibly for the driver. There are no power interruptions, which increases safety when performing overtaking and other high-speed maneuvers. PowerShift gearboxes has a manual switching function that allows you to change the steps at the request of the car owner. Note that individual modifications of gearboxes imply the installation on the steering wheel of special steering wheel switches, allowing the car owner to replace the steps without the dispersion of the automatic transmission.

In the "D" mode, the automation of the gearbox replaces the steps when revolutions at 2500 - 3000 engine speed per minute. It is possible to enable sports regime, in which the gearbox allows you to unwind the engine to 5000 - 6000 revolutions per minute. This activates a special system that allows, even when the manual gear shift mode is turned on, protect the engine from long-term operation at high speed. In this case, the gearbox will not allow car owners to independently enable reduced transmission, in which the engine will work on its maximum characteristics. Thereby ensuring the durability of work, both the box itself and the car engine. There is also a built-in oil temperature sensor, which not only determines the lubricant temperature, but also analyzes the quality of lubricating compositions. If necessary, automation warns a car owner about transmission problems available.

The recommended frequency in which the oil change in the checkpoint is required, indicated in the car operating manual, but it should also be given to many other factors: season, contamination, weather conditions, car use intensity. The oil in the gearbox is needed for smooth operation, as well as for the gears of the gearbox do not erase each other. Oil binds corrosion products and operation of mechanical parts of the gearbox, and also removes heat from the parts.

What does the box inside look like

The gearbox in principle consists of two sections independent of each other.

When moving, one section of the gearbox is constantly closed kinematically, and the next transmission is already enabled in another section, but the adhesion of this gear is turned off.
The primary shaft consists of two parts and is the heart of the gearbox. It consists of an external primary (hollow) shaft and an internal primary (central) shaft.
Primary (hollow) shaft activates even transmissions (2nd, 4th and 6th gears), as well as through the intermediate gear of the reverse transmission.
Primary (central) shaft acts odd transmissions (1st, 3rd and 5th gears).
Both primary shaft are connected accordingly through the external gear of the clutch disk.

Torque transmission is performed via the appropriate clutch disc, located in parallel for both gearbox sections. For security reasons, the double grip is designed in such a way that it is open at rest. This type of clutch is indicated as the so-called "closed clutch". In the closed clips, the clamping force is equal to zero, until a force is attached to the lever spring or an insignificant effort is attached. The clutches are equipped with an internal monitoring of wear correction control, it allows you to hold the necessary operation of the actuator and, thus, the required space for installation. In addition to quenching vibrations in the clutch wheels are built-in double jackets. Double clutch pulleys are installed on the primary Tree gearbox.

PowerShift 6DCT250 gearbox problems - what can be encountered?

At the moment, the main malfunction to flow the seal of the primary shaft, the oil falls on the clutch and slipping occurs. So, there were cases when the plugs (actuators) of the clutch enclosure. When leaks from the gearbox, it is necessary to replace 2 glands and the grip itself. In early 2012, the firmware was changed in the box, before that, Focus was crushed by jerks and vibration - when attaching, shifting gear or movement at low speed.

In most cases, due to improper operation of the gearbox and in the absence of due service, problems with PowerShift arise. That is why when operating this modification of gearboxes, it is recommended to perform all the necessary procedures for the transmission service. It is also necessary to warm the gearbox in the winter season, which will improve its lubricant and extends the trouble-free use of the automatic transmission.

The problems of the transmission PowerShift can also occur with the active and aggressive style of driving a car. According to experts and car owners with this type of automatic transmission, this transmission does not like fast driving and frequent switching steps.

Emergency mode

In TCM software, there are functions that intercept the control of the gearbox when a serious malfunction occurs.
The selection of the applied strategy is made on the basis of the nature of the malfunction.
The car remains ready for work to a limited extent if there is no error in the TCM module itself or in the TR sensor (gearbox range)
NOTE: If the TCM module is faulty, both clips are separated and the further trip is no longer possible. If the tr sensor has failed, the car start is not possible, or the gearbox is in position N and the further trip is no longer possible.
Depending on which the transmission position and in which road situation, a malfunction appears, different measures are taken.

When the electric motor fails, which includes a clutch lever executive element, the TCM module manages only a good electric motor. For example, when the electric motor is output 1, this transmission path is blocked (1st, 3rd and 5th transmission). The TCM module is now only the electric motor 2. It turns on the adhesion of the reverse transmission, as well as the 2nd, 4th and 6th transmission.

When the switching system fails or the speed sensors fails, the response to an error can extend from blocking individual gears and blocking the entire gearbox path (even / odd transmission) up to the possibility of motion only on the transmission already included.

In the emergency mode, the instrument panel displays a text message corresponding to a fault type, and / or MIL liter (engine control system test lamp) and / or a control lamp of the gearbox.
When re-started (ignition is turned off about 15 seconds), self-test is performed to check the presence of errors in the system. If the fault is then repeated, the emergency mode is activated. If there is no error, the indications on the instrument panel will not follow, and the MIL lamp and / or the transmission control lamp will not light up. However, the fault remains in the TCM memory. In the event of a malfunction, it is recommended to continue moving if possible along the shortest path to the workshop or put a car in a safe place.

Ford focus 3 automatic It has a 6-speed PowerShift automatic transmission with two clutches. This allows you to significantly improve the dynamics, the smoothness of the stroke, compared with the usual automatic box. In our article you will find photo Ford Focus 3 automatic and his description.

The main competitor and constructively similar automatic focus 3 PowerShift is a robotic DSG machine, which is installed on Volkswagen, Audi, Skoda and other concern models.

Robotic automatic transmission is quite popular in Europe, so in American Ford decided to develop their own version of the robot. Initially, he appeared on the Mondeo, and then on the focus. The first boxes "Pouroshift" on Ford Focus III behaved not very well, the owners complained about the problems at low speeds. Soon the manufacturer solved the problem, simply reprogramming the operation of the automatic transmission. Dry clutch allows you to transfer the maximum power torque power on the wheels. This makes Ford Focus 3 automatic not only dynamic, but also economical.

We all know that the ordinary automatic transmission when switching has some time delay, sometimes the machine thinks for a very long time that it does not allow certain maneuvers on the road. The main task of Ford designers when creating this automaton was as follows, reduce the moment of switching to a minimum, this technology was called Torque Hole Filling Technology (THF). Thus, the torque from the engine is transmitted almost instantly to the wheels.

The PowerShift machine for Ford Focus 3, this is an alloy of high-tech engineering embodied in the metal, plus an electronic control unit that tracks the operation of the engine, the current speed and instantly makes decisions. Initially, the 6-speed automatic with THF technology was available only for the engine with a working volume of 2 liters, but later it was possible to aggregate the paoushift automatic transmission with a 1.6 liter motor.

Ford Focus 3 Automatic, this is a combination of mathematical modeling and computer hardware, along with other promising technologies for mechanical transmission of torque. The most interesting thing is that the development of such a transmission began a few more decades ago. However, at that time there were no powerful computer systems for managing a similar automatic box.

Gold 1 million box at the 2011 Conder 2012

with wet clutch WD (Wet Dual Clutch)
with DD DD Clutch (Dry Dual Clutch)

The design gearbox is identical to the DSG box with a wet clutch, the difference in software and the number of gear: DSG is maximally 7, and PowerShift - 6. For VAG, the mechanical part and software developed a Borg Warner company, and for Ford - Getrag and LUK . DSG is tougher, with a light jerk at start and well-tangible braking engine for a dump of gas. In PowerShift, the switch is softer, almost like a classic hydromechanical machine, but it is possible to effectively slow down the motor only in manual mode. Specialized club service DCT + carries out the diagnosis and repair of the box of the Ford Focus Robot 3 in Moscow with a guarantee.

Decoding designations (getrag)

DCL - longitudinal location of the PPC (L)

DCT - transverse location of the gearbox (T)

6DCT / 7DCT - 6/7 speeds

250/450/750 - Transmitted torque in n / m

For DCT with low torque (up to 300 nm), DD enclosure boxes are installed. For more powerful cars, "wet" clutch WD (450/470, etc.).

For Ford Focus 3, 3 types of transmissions are installed: MCPP, automatic transformer automatic transformer automatic transformer, Powershift Robot Box (dry 6DCT250 and wet 6DCT450 for diesel versions).
