the main / KPP

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 their own vOLVO cars Uses the automatic transmission of famous manufacturers firms by exposing their 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.

XC90 automatic transmission filter with a metal grid, change them when overhaul Or if at least one friction escape burned.

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.


AW55-50SN automatic transmission on Volvo S60 and S80

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 vOLVO owners XC70 faced with the failure of the front transmission frictions the box is 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.

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 Executive Class Sedan

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 of the electronic engine control unit. 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.

Video: Volvo S80 - 2008. Review (interior, exterior, engine).

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.

With all reliability automatic box transmissions Volvo, the moment occurs when it has to produce its capital or maintenance. The reasons for the failure of individual nodes or transmissions are actually several, and the type of breakage, often depends on the car model and the "character" driving.

What are the most frequent causes of failure of Volvo automatic transmission? Basically, these are non-accurate switching of positions and sharp jumps of engine speeds, during which friction discs burn. This happens also because the operation of the oil pump is violated Volvo gear pump. The consequence is the challenge of the car, since the transmission simply does not have time to restore the pressure required to connect the clutch discs.

The most common automatic transmission of Volvo includes the following models: TF80SC, AW55-50SN, AW50-42LE, 4T65E and TF80SC.

The main problem of automation TF80SC, which is installed on the Volvo S80 and XC-90, is a hydraulic knob. Most often, after contacting this problem in Tower Center Volvo, the owner receives a proposal to replace the transmission to a new or used. The inconvenience is that the expectation of a branded new spare part can delay almost two months. Therefore, many owners of Crossover Volvo XC-90 make a decision to establish a unit in use, at least until the time that the new one comes.

The most problematic part of the Volvo Automatic Box is the valve control unit. There are two exit from this situation: either the inspection of Volvo with the replacement of the block is new, or repair. The latter will definitely cost much cheaper. However, there is a pretty good "but". If you have not applied to the Volvo technical center, and repaired in a non-core repair workshop, there is always a risk of an automatic transmission failure, even after repair activities. Therefore, many experienced professionals are recommended when breakdown to fully replace the valve control unit, in order to avoid new breakdowns and further unjustified costs.

The five-speed AW 55-50 / 51SN transmission is installed on the Volvo S60, S70, XC-70. If there is a breakdown of this automatic transmission, then most often required full replacement Pasters, seals, friction and steel discs, bushings and filters. In some cases, only the planetary transmission bushing is subject to replacement. It is important that one or another repair in the service center is performed according to the instructions of the manufacturer, in which highlights are painted. maintenance Volvo.

Modern technical center will help you solve all the problems regarding the diagnosis, repair or installation of the automatic transmission. Thus, the transmission of your car will be in the safe hands of experienced specialists who will be able to guarantee the quality of the work of each installed spare part.

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 C. electronic block Control, 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 a breakdown of the electronic part, the automatic transmission passes into the so-called emergency mode Transmission saving, the box no longer responds to switching the lever, one transmission is turned on to ensure the transportation 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 state 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.

The 4-speed automatic transmission was developed by GM in 1991 for the VOLVO front-wheel drive vehicles with 2 to 4 liters. 4T60E (installed on Cadillac'i) after a modification in 1997 was replaced by 4T65E. This box has proven itself quite comfortable and quite maintainable.

On the rivally running boxes, the first repairs are mainly in the repair of the hydrotransformer with a worn blocking, prophylactic repair of hydroblock and solenoids, which can lead to loss of pressure in packages and shocks in speeds. Hydrocks do not like superheated and dirty oil.

On running boxes (with runs for 200-250 tons. Weak place is a package of the 2nd speed, where the burned drum changes. If necessary, the preventive repair of differential (by repair kit) is made.

The resource of the repaired box is high enough if you monitor the oil level and do not overheat it.

The 5-step automatic transmission AW55-50SN was designed by AISIN engineers in the late 90s of the century for for front-wheel drive third-party manufacturers (different from Toyota / Lexus / Scion) with a volume engine from 2 to 3-liters. Calculated for torque up to 330 n / m.

This 55-50SN has applied many new technologies to improve the dynamic characteristics, comfort and ecology of the car. One of them is the use of linear solenoids (Solenoid Linear) for soft gear shift. It is this solenoid (SL) that makes switching imperceptible and practically without loss of power flow. Another innovation is the slipping mode of the torque converter blocking, which uses new materials from graphite. The locking of the hydrotransformer began to be turned on with a SLU linear solenoid already with a second speed (in mode gas in floor), without waiting for slow acceleration with the help of turbine wheels. As a result, it leads to a rapid wear of the friction lining of the hydrotransformer and problems with a hydraulic block appear along the chain (pinks, shocks, hangs, etc.).

In 2003, Aisin has developed a modification with AW 55-51SN code with an advanced hydraulic block for all-wheel drive cars.

Repair of the hydroblock with cleaning is better to produce as early as possible in order to prevent the typical and unreasonable problem - wear of the valve block housing. Depending on the state, a decision is made on the feasibility of recovery or replacement to the new one. In this hydraulic block, plungers are made of teflon and practically not wear out. Wear is the hull itself, besides, several valves are critically worn, which significantly complicates the diagnosis and repair.

The mechanical part is quite reliable, but if there are any problems with it, then planetary rows are followed by replacement, C1 / C2 drum, glazes, sleeves and less often Sunny gear, mandatory repair of the hydrotransformer.

Generally reliable boxIf not frying on it regularly, if you run 200 tons. km and it does not kick, it can be concluded in general that they did not fly on the car.

Since 2004, AISIN WARNER has begins to release a 6-speed TF80-SC automatic transmission for Ford, Mazda, Land Rover., PEUGEOT, CITROEN, OPEL, SAAB and VOLVO. A series of boxes TF-80SC is calculated for torque from 100 N / m LJ 420 N / m, mainly used for vehicles with an engine capacity up to 3 liters, and only on S80 and XC90 is installed its strengthened engine from 4 liters. The main differences in the mechanical part, sizes of packages and housing.

Also, AISIN has released a similar TF81-SC gearbox, which digested torque up to 450 n / m and is installed on Ford, Mazda and Land Rover. It differs in the number of solenoids, sizes of packages (as well as stories and frictions in them).

The main task of standing in front of the designers, in addition to increasing the number of transmissions, was an increase in the dynamics of overclocking and efficiency, reduced fuel consumption and have a compact layout (dimensions should be like mechanics). In this unit, the Aysin first applied an innovation: switch quality solenoids that work only during speeds, equalizing the values \u200b\u200bof the shafts and making the switching imperceptible (without jolts). Almost almost that predatory gearbox. The weight of the unit also decreased (compared to 5-speed).

The most modern graphite materials are selected for the friction converter friction pads, the programs in the automatic transmission control unit were adjusted by manufacturers in such a way as not to allow the driver to overheating the automatic transmission to the driver and at the same time to quickly accelerate the car, etc. In the early years after release, these programs were constantly updated, eliminating the "childhood diseases" of the first years of release.

As with the previous automatic transmission, the headache is the operation of the hydrotransformer - the main heat generator in the gearbox. The torque converter uses only one friction overlay for blocking the coupling, then when Jatco, ZF, etc. Already a long time ago, a basket of 2-3 full-fledged friction discs does not save space and increasing reliability have been put on such aggregates.

The program of the automatic transmission control unit allows the driver to extremally load the transmission, forcing the surveillance of the clutch of the hydrotransformer and starting the third transmission to transmit torque from the engine and switch to neutral at each other case to save the fuel and not overheat ATF.

The usual repairs are to repair the hydrotransformer (required), hydroblock (or replacing it in a particularly neglected case), all gaskets, pistons, friction, steels and filter with butter.

In TF-80SC, the oil of a new generation and the manufacturer declares that it does not change. But this is as usual marketing stroke, it is definitely better than the ATF of the previous generation. But the new super oil to derive suspension from the frictions and steels can still not, therefore, as a result, an oil starvation occurs after the channels of the valves of the valve block, which leads to the destruction of the mechanics (oil pump for example fails one of the first, drum director 4-5-6 speeds, package package with reference bearing, brake tape, etc.).

Also, after about 100 thousand km, it is necessary to pay attention to the subject of oils of oil (seals). Launching the level, you can get the box at times. These are not the condemned 4-rigs of the mid-90s.
