The problems of the control unit of the automatic transmission of Volvo with 80. Select a used Volvo S80 second generation (2006 days). Why automatic transmission operates in emergency mode

Automotive concern Volvo comes from Sweden. In addition to cars, it is engaged in the production of buses, trucks, engines, various equipment and construction machinery. For its cars, Volvo uses the automatic transmission of well-known manufacturers, exposing them to modifications under their own cars. Machines from Volvo are very reliable and durable, they are called "tanks". The automatic box used by Volvo, according to modern standards, is very reliable and durable. Repair of these transmissions will not deliver difficulties - they are well studied by specialists in Russia.

VOLVO XC90 car transmission repair

The legendary four-stage transmission A340 from Aksin was installed on VOLVO XC90 cars. It has been used since 1985 for rear and all-wheel drive vehicles with an engine capacity of up to four liters. This transmission was installed on the Land Cruiser, Sequoah, Pickup, Terrakan, Pajero, Mark2. This automatic can be rightfully called one of the most "unhappy". With a timely change of oil, this machine drills a million mileage kilometers. And it is on powerful engines with a huge torque and cars that are not spared. After a series of modifications, this automatic transmission is still used. And you can still find a car that rides on the very first batch of these boxes. About this automatic transmission say that it is experiencing a car first, and then the driver. And it rarely requires repair.

Remkompleks for Automatic transmission volvo XC90 You can order non-original, they are worthy of quality. Typically, XC90 transmissions are soldered to overhaul without any problems. Either the driver, the charter wait until the dying transmission, will die completely and he will reach the service itself and produces repairs.

A340 automatic transmission for Volvo cars XC90

For age-related XC90 cars, the set of frictional, steel drums and brake tape are changed. For SUVs produce "workshops", which contains everything necessary if overhaul is needed. Many elements can be ordered and reinforced. Tuned 340aya withstands engines, forced to 1000-2000 horsepower.

The XC90 automatic transmission filter is reusable with a metal grid, they change them during major repairs or if at least one friction escape burned down.

In the age-related XC90 cars, a hydrotransformer is always worn. His abnormal work displays the pump, its gland and the XC90 automatic transmission sleeve.

Recomplex for XC90 automatic transmission is included in the bushings, gaskets and glands. They are out of time and begin to skip the pressure. Sometimes plastic waders change together.

The braking tape on the XC90 automatic transmission is also subject to replacement, but sometimes they save on it and in principle, the box after such a "undersion" is completely reached to a well-deserved pension.

The electrical part is very reliable. Solenoids work out and fifteen years. For age cars, their replacement is shown. Rarely tired electric valve and pressure regulator.

Volvo S60 and S80 Transmission Transmission Repair

The Volvo S60 and S80 and S80 are equipped with six-speed AW55-50SN automatic transmissions made by Aysin. This transmission serves for front-wheel drive vehicles with a volume of up to four liters. The running of this transmission began in 2000 on VOLDO S60 and S80 cars. This transmission is found in car DEU., Chevrolet, Opel, Cadillac, Fiat, Nissan, Renault.

This automatic transmission is developed taking into account new technologies and trends in the production of automatic transmissions. Compared to past generation, automatic transmission in it is significantly improved. dynamic characteristics, Comfort and environmental friendliness of the car.

The S60 and S80 automatic transmission S60 and S80 uses linear solenoids for more smooth inclusion of gears, virtually no power loss. The second innovation is the mode of slipping the locking of the hydrotransformer and the manufacture of the cluster of the hydrotransformer from more durable graphite materials. The locking of the hydrotransformer in the S60 and S80 automatic transmission is activated by the second transmission, which increases the wear of the friction converter, but increases acid characteristics.

The filter of the S60 and S80 automatic transmission is two species with the edge of Lee without. With a rib has best featuresBut they are not interchangeable, "jar" will not work. Filter filling different for different modifications. There may be a felt, and a metal grid. After 2004, Toyota WS oil is suitable for this box and no other. The S60 and S80 S60 and S80 solenoid settings are too accurate and they are calculated on this oil.

Repair kits can not be taken original, they are produced sufficient quality.

In the first years of production of transmission, the main problem was the hit of antifreeze in transmission fluid. Fortunately, this lack eliminated and now this repair is not required. The first modifications of the hydraulic block were not very reliable, but since 2004 they are produced quite strong.

There were no more special problems with this transmission.

The innovation of the slippage mode has adversely affected the oil service life. It is rapidly contaminated by the spree of the friction tip of the hydrotransformer. In turn, dirty oil pollutes the hydraulicock, scores from the solenoids, valves and the slab itself. The S60 and S80 automatic transmission plugs are stuck in dirt and oil ceases to reach clutch packages, which leads to their burnout. This is the cause of most of the premature repairs (up to 200,000 kilometers) is automatic transmission.

The main symptom of the S60 and S80 automatic transmission problems is to switch between the second and third gear. They begin to delay or occur with the blow. From shocks when switching can suffer the brake tape.

Repair of the hydroelectric lines of five- and six-track automatic transmission is rarely produced. This is an absolutely unprofitable occupation, and and find a specialist can be very and very difficult. The only thing that is produced by cleaning the hydroblock and the replacement of solenoids. In other cases, it is a replacement of the hydraulic block.

Among the popular replacement for automatic transmission S60 and S80 - repair of the pump meter and pump cover sleeve. Typically, these problems are followed immediately for the ride on a worn outroth transformer when overhaul is made. If the repair of the hydrotransformer does not do, then it does not make sense to eliminate this problem. Repair the hydrotransformer is standing with every major repairs, since it is its friction pad and is the main cause of problems and breakdowns of this automatic transmission. Oil fasting from the garbage of the hydraulic unit is affected on the sleeves, they begin to skip the oil and the remaining mechanisms of the box are already suffering from this.

With the overhaul of the adult car, all the frictions are changed, steel discs and brake ribbon. They also suffer from dirty oil and friction wear of the hydrotransformer.

From electricians to the automatic transmission S60 and S80 often change solenoids and a speed sensor.

By the gland, the box is very reliable. For extreme riders, sometimes ordered rear planetary row and some drums. The drums are wearing teflon rings and seats. Sometimes the problem is intensified from the brake tape tired. The consequence of these problems may be a bummer of teeth of the solar gear.

For age automatic transmission of this model, the installation of an external filter is shown. thin cleaningwhich will significantly increase the life of the box.

Recent modifications of these boxes with a calm ride and timely replacement Oils and filters are practically not broken. But the aggressive and inattentive driver can drive them less than 15,000,000 kilometers.

VOLVO XC70 car transmission repair

Volvo XC70 cars are equipped with six-speed TF80SC transmissions from Aysin. Works in a pair with motors of up to 4 liters for cars with front-wheel drive. This transmission is actively used in many brands of cars: Ford, Mazda, Fiat, Peugeot, Opel, Renault, Citroen, Saab and others.

Automatic transmission TF80SC on Volvo XC70

The history of this automaton in Volvo cars began in 2001. Aysin engineers set themselves the task of making the most technologically advanced and modern transmission. They increased overclocking characteristics, fuel efficiency and switching comfort. At the same time, the development remained at the level of "unhappy" Toyotovsky automatic transmission. And all this managed to put in the open space, taking place in size with mechanical box Transmissions. Practically 100% efficiency, softness and efficiency made this transmission direct competitor robotic boxes Transmissions. Overlooking them for comfort and reliability. The Volvo XC70 transmission practically returned hydraulic transmissions to the market, again by making them competitive. It is in the literal word of the masterpiece of engineering thought.

The electronic unit management Volvo. XC70 will not allow the driver to overload or overlay the box. Many elements and mechanisms of Volvo XC70 automatic transmission are made of modern materials and have a huge resource.

Diseases of this automatic transmission are not related to her constructive features. Usually they arise with the correction of the customer's engineers in their cars and incorrect configuration. So, for each car model they are different. Some cars with this automatic transmission are very reliable, some not very.

Volvo XC70 with TF80SC automatic transmission

The main headache of the owners of the Volvo XC70 is the wear of the hydrotransformer. And this is normal for five- and six-speed automatic transmission. The Volvo XC70 automatic transmission includes a friction pad and this is the only irreplaceable solution. The remaining manufacturers have long used bearings.

Sometimes the owners of Volvo XC70 are faced with the failure of the Friction of the front transmission box very sensitive to the burner and dirty oil. When exposed to dirty oil on automatic transmission for some time, it is worth paying attention to the state of the hydroblock, solenoids, friction, sleeves. By hardware, this automatic transmission is very reliable.

Volvo transmissions repair do it yourself

Modern transmissions are very complicated and in case of their failure to deal with the way without the help of professionals can be very difficult. And such a decision may not save money, but only make it worse.

Good day! I have a Volvo S80, automatic transmission. All solenoids are going too weak, after they are replaced, the error remains the same, the wiring was sounded, everything is in order. Tell me, please, what could be the problem? (MUSA)

Why does the automatic transmission operates in emergency mode?

The reasons for which "automatic" can go mode, maybe several:

1. First of all, it may be due to a lack or oversight transmission Oil. The incorrect level is the cause of failures in the operation of the control unit, which will force it to turn on the accident.
2. Problems may result from malfunction of the mechanics of the unit or hydraulics. In particular, it can be directly defects of the CPT housing itself or a malfunction in the work of the friction group. It is necessary to dismantle the pallet and inspect it - if the traces of the metal chips are visible or removed, then you will have to check each component of the aggregate. In computer diagnostics, such problems do not always pop up.
3. Another reason is malfunction in the management of the control system. In particular, the temperature control sensor could fail. You need to change the element. In addition, we will recommend you to diagnose the camshaft regulators, throttle valve, Air flow sensor and ABS.
4. Perhaps the problem lies in the devices of rotation of the input or output pulleys. Either a malfunction and at all lies in the operation of the control unit.

Are you sure that you have done a qualitative diagnosis? Perhaps it makes sense to contact other specialists for help? Sometimes the fact that some people cannot make, it is easily obtained from other masters. If our recommendations did not help you, we advise you to distribute your car yourself with the help of a tester and a laptop. Or entrust this is the work of professionals.

Video "Box machine in emergency mode"

How the "Automatic" works in emergency mode - look at the video.

Volvo 4T65E, TF80-SC, 55-51SN, 55-50SN is a reliable mechanism, but during operation, it takes place of parts, it often occurs from an automobile owner.

This often leads to a decrease in service life and automatic transmission.

Signs of the breakage of the box automatic on Volvo - when must VOLVO be given to the service for diagnostics?

Main errors of motorists, leading to the battery breakdown, is a sharp overclocking, riding with slip, non-compliance with the technical intervals.

Regarding what kind of Volvo you have - S80, XC90, S60 or XC70, and which automatic transmission - whether it is 4-speed 4T65E for Volvo Cross. Country, or 5-speed for Volvo S60, if you want it to serve you for a long time and reliably, it is necessary to make a diagnosis .

We also draw your attention to the fact that every car owner has its own way to drive. Most do not even suspect that it is fraught with the consequences for automatic transmission, therefore, purchasing cars on secondary market, Be sure to diagnose automatic transmission.

Below are given signs of misappropriate operationsIf there is even one of them, it is necessary to diagnose in a specialized location.

• Box stacks.
• Dips in the dynamics of a speed set ("slows down").
• Speed \u200b\u200bswitches jerks.
• When switching the lever, a jerk occurs (the box "kicks").
• When you click on the accelerator pedal, the box "thinks", "freezes".
• Car vibrations worth checking automatic transmission.
• Foreign noises and knocks.
• The check on the dashboard caught fire.

Typical vehicle breakdowns Machine on Volvo - How is the inspection and repair of automatic transmission on Volvo?

During the operation of the automatic transmission for Volvo, various sorts of breakage may occur, and for various reasons. If the automatic transmission with an electronic control unit, then breakdowns are divided into two groups.

1. First group - These are breakdowns associated with electronics control of automatic transmission.
2. Second group - It is a breakdown of the hydro-mechanical part of the automatic transmission.

Fault electronic system Management:

Basically, when breakdown, the automatic transmission passes into the so-called emergency transmission mode, the box no longer responds to switching the lever, one transmission is turned on to ensure the transportability of the car to the nearest service.

Diagnosis of these types of breakdowns are produced by a special computer scanner. It is very important to determine these breakdowns at the diagnostic stage, as the repair of the ECU is produced without a meal

Malfunctions of the hydro-mechanical part of the Volvo automatic transmission:

If a vehicle When you turn on the gear does not respond to commands, in the box foreign noiseIf it moves with slipping into the automatic transmission, the breakdown is associated with friction discs, planetary transmissions, a pump, a torque converter, wear of the sleeves and bearings, due to the damaged brake tape.

The diagnosis of the hydro-mechanical part without inspection at a stationary point cannot be made, as it implies the parsing of the automatic transmission Volvo. Some of the listed breakdowns of the automatic transmission are detected using the scanner, but the repair without parsing is no longer possible.

Examination of the automatic transmission for defects occurs in stages:

• Check automatic transmission Volvo computer scanner for the performance of all systems.

In Volvo, all car control systems are connected, so if there are problems of functioning, admit to ABS, it is also reflected in the work of all other systems, including in the automatic transmission.

• Visual inspection on the signboard.

The oil level and condition is checked:

The oil level in the Volvo automatic transmission is checked only with the engine, if on the cold, then the oil should be at the bottom of the mark, if it is hot on the top of the probe. Removal, as well as overflow fraught with the consequences for automatic transmission, the lack leads to overheating and increased wear of the Details of the automatic transmission. The state of the oil is indicative indicative of the status of the box, the frictions are damaged. And it will soon be repaired.

Visual inspection for leaks. Cooling radiators condition:

The presence of leaks from the Pallet of the automatic transmission of Volvo shows that it is necessary to check the oil level and replace the laying of the box pallet. The contaminated radiator cooling the automatic transmission leads to increased heating of the oil, and since the box creates already high pressure And the temperature (\u003e 120 degrees), this leads to an increased load on the pressure regulator and the oil pump.

Most of our car enthusiasts still believe that it must be German. And even those who are looking for themselves, are still primarily focused on products from Germany. But there are still a lot of interesting options, which also look much more attractive for the price. Volvo S80 second generation - just one of these options. Swedish sedan looks still stylish, pleases with a spacious interior, spacious trunk and a sufficiently large number of power units. But can the Swedish car be able to argue with his German competitors in terms of reliability? Now find out.

VOLVO S80 II Body Problems

But with chrome details, which for 3-4 years lose their gloss, more complicated. Menten them is expensive, so most owners just do nothing with them. Also before buying, be sure to check the integrity of the washer tank. On many cars he crashed. It is possible that along with it will also have to change the hoses of the headlights. They also tend to crack over time.

Possible interconnect problems

There is no complaints to the salon of the Swedish car. All materials used in it are very high-quality, so you should not hear any squeaks of salon plastic. But checking the electronics to share a little longer. Start by checking the health of the heating system of seats and climatic installation. Due to the faulty temperature sensor, which is inside the car, climatic installation Can serve exclusively hot air into the cabin. It is possible that, together with the sensor, you will have to change the stove motor, which after a run of 150 thousand kilometers begins to a freshly creap. To the same mower, many VOLVO S80 owners will have to change the bearing of the generator clutch.

Problems with Volvo S80 II

Powerful 4.4 liter gasoline engine

When choosing a motor, it is best to give preference petrol aggregate volume of 3.2 liters. It is considered the most reliable. Yes, and the chain used in this engine In the mechanism of gas distribution, will save from excess headaches. In a more powerful gasoline engine with a volume of 4.4 in the gas distribution mechanism, a chain is also used, but a constructively, this unit is much more complicated, so you can buy a car with it only if you firmly have decided that you are not going to save on service.

But most often in our market there are cars with gasoline engine 2,5t. In this force aggregate Every 90,000 kilometers will have to change the belt in the mechanism of gas distribution. Also be prepared for the fact that it is necessary to change the oil level sensor, and after a run 150-170 thousand kilometers may require replacement of seals of camshafts and crankshafts, which by this time begin to "hinl".

Among other problems that are characteristic of engines installed in the Swedish sedan can be noted the failure of the ignition coils. And with their replacement, it is better not to delay, since the operation of the car with damaged coils will very soon lead to the failure of the microcircuit electronic block Engine control. We will have to buy a new module, and it is very expensive. Also not be lazy to periodically pay attention to the condition of the cooling system fan. After a run of 180 thousand kilometers, he may fail.

VOLVO S80 gearbox work

Automatic gearbox, and most of the Volvo S80 II generation will be with it, after 50 thousand kilometers, it starts to get enough to buzz on the first gear. But the manufacturer assures that this is not a malfunction, but a feature of work. And it looks like the truth, because then the "automatic" works without any particular problems. And only after a run of 200 thousand kilometers, he begins to switch transmissions with noticeable jerks. You have to change the guide bushings in solenoids. And if you are not lucky, you will also go to the replacement and friction with hydroyodul. And in this case, the repairs will cost really expensive. So before buying, especially if you have at least the slightest suspicions, the automatic gearbox is better to properly digitize. And after buying a car, we immediately change the oil in the "automatic". This will increase its service life.

Suspension and steering

The Volvo S80 suspension of the second generation is quite reliable. Only after 100 thousand kilometers she. First you have to change the front shock absorbers and support bearings. Then there will be a series of silent blocks and balls. After run 150-170 thousand kilometers of replacement will require hub bearings. And note that on some Volvo S80 II, a suspension is installed with shock absorbers adjustable. Her "consumables" will be more expensive.

With the steering control of the Swedish car there should be no special problems. After 100 thousand kilometers on some cars, the hoses in the hydraulic steering amplifier begin to leak, but this problem did not become the mass. From time to time the owners of Volvo S80 II complain about steering rack. But she, if you compare its resource with that on competitors' cars, it is quite reliable.

So is it worth afraid of the Volvo S80 of the second generation with mileage? Unlikely. If you compare the level of reliability of the Swedish car with competitors, and they are BMW Fifth Series, Audi A6 and Mercedes Bens E, the "Swede" looks even preferable. But it is important to understand that the service and repair of the representative class car can not be cheap by definition. So that possible repair In any case, it will require very serious costs. Ready for this? Then forward in search of a worthy car.
