This transmission has all modern security systems from overheating. Friction components are selected with steel discs for each type of engines, require correct positioning during installation (for efficient cooling),violation and get burnt in case of violation of operation rules. The friction lining wear-out increases clearances in the package and the transmission starts shifting gears improperly. Before replacement of friction components it is recommended to consult an authorized DSG BMW service, because it may be possible to adjust shifting with worn-out frictions with the use of software.

Transmission general data In 1987 Ford and Fiat started to produce the type of automatic transmission called CVT. This innovative system was designed on the basis of the Van Doome mechanism, which was installed in small cars (DAF) in 1955. The Ford CTX transmission operates on the principle of belt driving applied in Van Doome transmissions, but with some peculiarity, namely, usage of a single steel belt (operating in compression) instead of two rubber drive belts (operating in tension).

It is claimed, that this transmission is more economically viable solution in comparison with usual automatic gearboxes. This transmission has a smoothly shifting gear ratio over the entire speed range. Transmission of the torque from the engine to the main drive shaft is performed not via converter, but through the multi-plate clutch. The transmission control unit provides an optimal gear ratio for any driving mode with a maximum efficiency coefficient of the engine. There is a kick-down mode which facilitates to the speed increase in cases of overtaking or uphill movement. This mode is activated when the accelerator pedal is fully depressed and held in this state.

The clutch drum К1 Due to construction peculiarities of the 722.7 unit and its valve body (VB), at one of the phases of clogging and aging of the 722.7 electrics transmitted excessive pressure on this pack damages the metal of the drum with the piston or pulls out the closing ring, that leads to slipping and necessity for change of the entire clutch cover K1. Preventive measures include well-timed cleaning of the VB unit, or well-timed change of the TC lock-up clutch after gearbox travels 150-200 thousand kilometers. 2.Valve body electronic plate For proper diagnostics and repair estimation, it is necessary to obtain error codes. Change of the board sensors or wiring of solenoids demands classification of the specialist and programming capabilities for encoding the plate for VIN of the car. Mercedes electronic boards are sensitive to the water, temperature difference, metal chips in oil. Each time diagnostics detects various causes of abnormal operation. The minor repair helps to delay the preventive repair for several years by means of cleaning\washing of the VB unit, repair of the electric plate with broken sensors. Operation with overheated oil damages the electronic plate extremely fast.

Transmission general data TOYOTA K210 / XA-15LN Simultaneously with the first generation of CVTs (K110/K111/K112), the Japanese company Aisin designed a lightweight CVT version K210 intended for small cars (with engine capacity of 1.0-1.5 liters). The right-hand drive Toyota Vitz (engine capacity 1.3 liters) was the first car equipped with this CVT. This car was intended for sale on the domestic market of Japan. Toyota wanted to test this CVT in Japan and fix all possible issues. The first upgrade of K210 was implemented in 3 month after its launch – Aisin engineers changed the belt. This measure helped to improve the car performance reliability at idle speed. In 2004, CVTEC Co., Ltd started production of 30-millimeter CVT belts, which found application in K210 (before that, the K210 gearbox was equipped with the belt of the Dutch company VDT BV). Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type∞CVTFWD14585Aisin CVTF7004, Toyota 08886-02105 For the external market (car models not including Toyota), Aisin produced the modification of K210 named as XA-15LN. From 2007 to 2014, this CVT had been successfully used by the company Mazda in its cars (Mazda Demio and Mazda Axela). It should be noted that modifications of the K210 transmission are not interchangeable (or partly interchangeable). The range of K210/XA-15LN did not receive any continuation. CVTs of this series were installed on a limited number of models of Toyota and Mazda for the domestic market of Japan. These CVTs had been produced before the end of 2015. In 2004, Aisin developed a new range of CVTs (K410/K411) for Toyota cars with 1.3-1.5 liter engines. This series turned out to be quite successful. Typical problems: 1) CVTs of K210/XA-15LN series (as well as other CVTs produced by Aisin) are extremely sensitive to ATF quality. In this case, we are talking not only about the presence of metal shavings in ATF, but also about ATF overheating. Shavings in ATF are actually abrasive particles, which eventually (if ATF is not changed) damage Teflon rings in CVT. Then it leads to ATF pressure drops in the transmission itself. Severe wear of Teflon rings over time leads to damage of friction clutches and steel discs. 2) Overheating of the CVT K210/XA-15LN often leads to complete replacement of friction discs. If the driver continues using the transmission with burnt ATF for a long time, then ATF not only loses it qualities and cools the transmission insufficiently (often it leads to overheating and replacement of pistons), but also poorly lubricates cones (especially in winter mode). It leads to slipping of the belt in winter time. Early versions of K210-11A CVT modifications were equipped with belts of the company VDT BV. These belts are not interchangeable with later modifications of belts produced by “CVTEC Co., Ltd.”. 3) Shavings (if ATF is not changed) reach bearings on the input and/or output shaft of cones and eventually one of bearings starts “buzzing”. Bearings are not very expensive, but replacement of the “buzzing” bearing is possible only with removal and complete disassembly of CVT (this procedure is time-consuming). 4) Some drivers had to deal with the problem of seal leakages in K210. Replacement of seals is usually combined with ATF change Which cars run with this gearbox?BrandModelYearTypeEngineDaihatsuBOON10-16CVT FWDL4 1.3LDaihatsuBOON/BOON LUMINAS10-11CVT F/4WDL4 1.3LSubaruTREZIA10-16CVT FWDL4 1.3LSuzukiSPLASH08-11CVT FWDL4 1.2LSuzukiSWIFT07-11CVT FWDL4 1.2LToyotaPASSO10-16CVT FWDL4 1.3LToyotaRACTIS06-11CVT FWDL4 1.3LToyotaVITZ05-16CVT FWDL3 1.0L

Transmission general data The CVT VT2 transmission was released in 2009 and was offered to numerous carmakers (Brilliance/BYD/Chery/Geely Emgrand/Great Wall/Tengyi/Haima 3/Freema/Hyundai Avante HD hybrid/Huandong /Toyota Vitz). CVT transmissions VT1 and VT2 have a reliable design (with a significant safety margin of transmission components) with a push belt. For many years, maintenance and repair services for this CVT are limited to change of oil and filter, and later – replacement of the Bosch belt. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type∞CVTFWD18283,1EZL-799-A45 The software of VT1,2 is designed to spare expensive cones at low speeds, when the belt and surfaces of cones operate very intensively. The cones have wear-resistant coating of operating surfaces implemented with the help of space technologies. These cones cannot be rebuilt and are not supplied to repair markets. The valve body filter in the VT2 transmission is based on Jatco solutions. Rare overhauls accompanied by reassembly of spare parts, the wear of which leads to pressure losses on the friction clutches and their consequent wear, require the repair kit of gaskets and seals. Repair specialists prefer to use Precision repair kit. Experienced transmission repair specialists, who work with VT1 and VT2 transmissions, change the filter and ATF as often as possible, because it is extremely hard to find spare parts for these transmissions. While changing the filter and ATF specialists usually check the chain (belt) for wear of the protector and in case of any suspicion of wear – replace the belt. The 30-40% wear of the belt teeth increases the risk slippage (metal-on-metal), even with the common (not sports) acceleration to outrun the truck ahead. If the surfaces of cones have tears or "pits", then specialists advice to replace the CVT instead of its repair. Generally, the VT2 transmission is considered to be "invincible” under the condition of proper maintenance. Today, it is one of the best CVTs on the market.

Transmission general data 8-speed CVT 0AW (VL380) was produced by Audi in 2004 for 4WD Audi models (from А3 (Sportback) to А7 (Sportback)) with gasoline engines from 1.8 to 3 liters to replace the 6-speed transmission 01J. In 2007, the new modification of this transmission named VL381 was produced. This CVT inherited only few spare parts (friction elements, steel disc etc) and the operation principle from its predecessor 01J. Electric components and the valve body were significantly improved. This smart transmission can send a huge torque (for CVTs) - up to 400Nm. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type8CVTFWD/AWD4005.5-7G 052 516 A2 Technical issues and repair guidelines There is still some old peculiarity of this transmission, which is related to the pulling chain – if the car equipped with this transmission is used for towing, then the cones with the chain get damaged without a chance for repair. Parts for repair of the 0AW transmission (besides an internal filter) are quite rare and available on request. For example, one of the typical issues is burning of the clutch drum. The internal filter is the same as for VL380 and 381. Filters are produced for deep and small pans.The list of required spare parts also includes the belt, which should be replaced without waiting for the moment when very expensive cones may be damaged. The price of these cones is comparable with depreciation value of the vehicle itself. The pulling belt gets stretched pretty fast because of extreme loads. Automakers give different figures regarding the belt service life before it should be replaced, but all of these figures are much lower than 200 thousand kilometers, therefore the belt is included in every second order for the overhaul of the 0AW transmission. In rare cases, it is necessary to replace a very expensive TCM (control unit) – valve channels of this control unit can be damaged by contaminated ATF.

Transmission general data The 8-speed 0С8 (or TR-80SD according to Aisin) is a new generation of Aisin RWD transmissions. It was designed in 2006 for VAG (Volkswagen-Audi) as an alternative to DSG, which still can not function reliably with powerful engines. This transmission was installed on Audi Q7 equipped with diesel engines V6-V8 from 3 liter capacity, and the torque capacity over 700 Nm. The same trasnmission design adapted for off-road Lexus cars has been used since 2007 under the name AA80E\F. In the winter of 2010, this 8-speed transmission fully entered the foreign market, where it replaced its 6-speed predecessor TR-60SN on Porsche Cayenne (2010 - 2014) and on Tuareс (2010 - 2014) in different sub-versions for TDI diesel engines with the capacity from 3.0 up to 3.6 liters (Audi -TFSI). This transmission was used by American automakers for Cadillac CTS VSport in 2014 under the name TL-80SD. The competitive model for above mentioned gearbox is ZF 8HP70. This transmission was designed with usage of successful TR60-SN elements, but the valve body and the overall construction of transmission components and electrics were significantly modified. Most of the parts are not interchangeable with the predecessor. It is the most powerful of modern RWD Aisin transmission capable of transmitting the torque up to 800 Nm. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type8ATRWD/AWD85010,58Toyota ATF WS Technical issues and repair guidelines This gearbox as all Aisin RWD transmissions is considered to be “invincible” and maintainable, designed to travel up to one million kilometers with minimum number of overhauls. The repair kit of gaskets and seals is ordered for reassembly in order to restore leak resistance of jointing edges by replacement of rings and gaskets that helps to the valve body in regulation of gear shifting by the oil pressure. The whole kit of friction elements is replaced when some components get burned. At the same time, it is recommended to change the torque converter frictions in case of burned ATF. For this transmission automakers used a new torque convertor with a multi-disc lockup clutch in order to guarantee a prolonged service life of torque converter frictions (over 200 thousand kilometers) and at the same time allow the driver to accelerate with the help of forced blocking of the torque converter lock-up clutch in "slippery mode". It significantly increases the transmission efficiency, improves acceleration characteristics, but wears out hard-working frictions of the lock-up. The valve body of this transmission differs from its predecessors TR-60 and TF-60. This valve body will get clogged if it is used with contaminated ATF for several years. Aisin solenoids in contrast to ZF solenoids can withstand much more open-close cycles.

Transmission general data The constantly variable transmission (CVT) JF009E (RE0F08A) is constructed for the class "mini" and can be paired with engines up to 1800 cm3. In 2002, the RE0F08A unit replaced not very popular RE0F21A modification. The JF009E transmission found application in various Nissan models, (1.8L Nissan Serena, March, Cube 2000-09, Micra 03-09. FIAT Punto, Palo, Uno 03-09...), but became more popular in Nissan Cube, Tiida and Wingroad. In terms of design, this CVT is similar to neighboring Jatco variators and comes between highly-demanded JF011E (for the middle class) and JF015E (for the class mini/micro). Many spare parts from the RE0F21A unit are interchangeable.

This CVT is sensitive to contaminated and cold transmission fluid. But in general, components of this CVT have an immense reserve for aggregated engines, serving for a long period of time even with contaminated fluid and clogged filters. The main coarse filter (made of metal with a mesh) is located in the pan and operates for a long period of time. This CVT also has an external fine filter, which is usually changed every 50-60 thousand kilometers. The reassembly includes spare parts replacement (Repair kit of gaskets and seals). The design of this CVT family is developed for engines with a higher torque and has such a solid reserve of CVT components, that it gets in repair services when the car itself exhausts its resource, therefore repair procedures in these CVTs are so rare.

Transmission general data The 4-speed automatic transmission A174 (TW-40) belonging to the "micro" class with a rear drive was designed by Aisin in 1998 on the basis of 3-speed predecessor А172. After testing and update, this transmission was installed on Suzuki Jimni, Escudo, Avery (Landy) with engines from 0.7 up to 1.3 liters. This automatic transmission is considered to be a modern, economical and “invincible” unit for the minimum torque (up to 120 Nm).

Transmission experts assume that it is necessary to replace all friction clutches (soaked with oil combustion products) in transmissions operating with burnt oil. The valve body design of this transmission includes "On-Off" solenoids (responsible for gear shifting and the torque converter lock-up operation), and a big EPC solenoid. Solenoids are adjusted quite accurately and ensure the torque converter actuation without a hard slippage. Therefore the torque converter does not overheat or smudge solenoids too much, allowing solenoids to operate for quite a long time. Sometimes problems occur in wiring of solenoids.

Transmission general data TOYOTA ECVT P110 / P111 / P112 / P210 / P310 / P311 / P312 / P314 / P410 / P510 CVT-type automatic transmissions are produced by Aisin for hybrid cars Toyota and Lexus. These transmissions have an initial prefix “P” (it means that these transmissions belong to the planetary type). Some people mistakenly believe that the planetary gearbox cannot be a CVT, but it’s wrong. Planetary gearboxes (not all) have a metal chain (analog of a belt in CVT). Even Toyota considers these planetary gearboxes as CVTs and name them as eCVTs. Undoubtedly, the planetary gearbox differs from standard CVTs (on the global scale the planetary gearbox is not so complicated as CVT), but it is still CVT with its problems and repair peculiarities. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type∞ECVTFWDTOYOTA CVT FLUID FE The first CVT of the planetary type eCVT (model P110) was manufactured in 1997 and was installed on the first generation of Toyota Prius for the domestic Japanese market. In 2000, this CVT was upgraded for Prius and was named as P111. Toyota Prius equipped with the P111 transmission was sold not only in Japan, but also in the US. The new planetary CVT P112 was designed in 2001. This gearbox was intended for more powerful (2,4 liter engines) and heavyweight cars (Toyota Estima Hybrid and Toyota Alphard Hybrid). The planetary CVT transmission P112 found application in Toyota Prius, which was sold in Europe, Canada, and USA. The P112 actually became one of the most popular CVTs of planetary type. The planetary CVT P310/Q211 (named as Q211 for Lexus) was manufactured in 2005. This transmission was specially developed for SUVs with FWD and 3.3-3.5 liter engines. This transmission was installed on hybrid cars Lexus RX400H, Toyota Kluger Hybrid. The planetary CVT P311 was released in February 2006. It was intended for FWD cars with 2.4 liter engines. In comparison with P112, this gearbox is noted for reduced fuel consumption when the engine has high RPM rates. In the same year, Aisin started production of the transmission P312 which was designed on the basis of P311. This transmission was supplied to Nissan Motor Company Co., Ltd (for application in Nissan Altima Hybrid in the US market. It was also installed on Toyota Harrier Hybrid 3,3 for the domestic market of Japan. The eCVT P410 was launched in production in 2009. This transmission was developed for FWD cars equipped with 1.8 liter engines. Peculiarities of this transmission include transfer gear case assembly and possibility of smooth reduction of the engine speed at high RPM rates. This eCVT as well as P112 found application at a global scale, because it was installed on Toyota Prius, which had been sold from 2009 to 2015 all over the world. In addition, the P410 transmission was used for a new range of cars ( Toyota Prius Alpha, Toyota Prius V, and Lexus CT200H. In July 2009, Aisin released a new modification of eCVT named as P311-03A. This transmission had an upgraded oil pump and engine cooling system. In 2010, Aisin started production of the P410 planetary CVT for plug-in hybrid vehicles. In August 2011, Aisin started production of a new planetary CVT named P314 for 2,5 liter engines (for FWD and AWD). This transmission was equipped with a new oil pump, which ensured lower fuel consumption. According to Toyota plans, this transmission also should find a global scale application, because cars equipped with this transmission are sold all over the world (Toyota Camry Hybrid (for markets of the US and Japan), Lexus NX300H (for European market), and Toyota Rav4 Hybrid (for all global markets). The P314 eCVT is considered to be quite “new” and it is rarely found in repair services. In November 2011, Aisin released a new eCVT transmission named as P510. This gearbox has a new design and operates with an NZ-series engines (engine capacity = 1.5 liters). The list of cars which use this transmission includes Toyota Corolla Hybrid, Toyota Yaris Hybrid, Toyota Prius C. The P510 transmission in noted for its light weight, small dimensions, and increased efficiency. In January 2016, Aisin released a new eCVT P610. This gearbox was intended for application in a new generation of Toyota Prius. Problems and repair procedures Abrasive particles often damage oil pump of eCVT , in case of ill-timed ATF change. 1) The planetary gear set wear is often caused by abundance of metal shavings. It is especially common for planetary type CVTs P112 installed on Toyota Prius (produced in the 2003-2008 timeframe). 2) Repair services for eCVTs often include replacement of gaskets and seals (Overhaul kits), pump seal, axle shaft oil seal.

A year later (in 2011) the K110 transmission was installed on sedans Toyota Alion/Toyota Premio and minivans Toyota Voxy/Toyota Noah/Toyota Estima, etc. All these right-hand drive cars were originally intended for sale at the domestic market of Japan as well as in some Asian countries. For 4 years of production, Toyota managed to fix some standard issues related to this CVT. In 2004, Toyota released an improved version of K110 which was named as K111/K111F (prefix “F” means that this CVT is intended for all-wheel drive vehicles). The K111 transmission was designed on the basis of K110, and these two transmissions are very similar in terms of technical solutions. The K111 transmission (in contrast with K110) has a new belt as well as linear control over the N gear and acceleration. It has a positive impact on fuel efficiency and transmission performance characteristics. For some time, Toyota was actually “catching up” with other Japanese companies in terms of CVT application. Therefore, Aisin (which produced CVTs for Toyota) had to use spare parts of different manufacturers for assembly of K110 and K111. Moreover, Aisin heavily depended on third-party suppliers and on quality of supplied spare parts. For example, belts for Aisin CVTs were produced by the German company Bosch. Toyota didn’t want to put up with such state of affairs. The Japanese auto giant wanted (via its subsidiary Aisin) not only to fully control the whole process of transmission production, but also to develop and introduce new CVT technologies. Thus, in 2002, Aisin jointly with Bosch established a joint company Shivutech Co., Ltd. (trade mark CVTEC). The purpose of this company was the development and production of components for CVTs. Three years later in 2005, CVTEC developed the belt for a new type of CVT. According to the original technology, this new push belt consists of thin steel sheets with high-precision gaps (equal to several microns). This solution ensures high strength of belt elements. In addition, the durability of this belt was enhanced by the sandblasting procedure. These measures made it possible to launch in production a new series of CVTs K112/K112F in October of 2005. These CVTs with higher torque transmission capacity were initially intended for coupling with 2,4-liter engines. The first car equipped with the K112/K112F transmission was Toyota Rav4. Later this CVT was applied in Toyota Estima, Toyota Blade, Toyota Vellfire and many other cars. Typical problems in K110/K111/K112 Transmission specialists often have to deal damage of bearings on the input shaft of K111 and K112. This problem may be caused by production defects or contaminated ATF with metal shavings. These metal shavings reach the bearing via a small hole in the gearwheel. As a result, balls in the bearing become cemented leading to its wear. Over time, the “dying” bearing damages the gear-wheel itself If K110 / K111 / K112 transmissions get overheated (ATF has a “burning” smell), then it may lead to replacement of the complete set of friction clutches. In this case, transmission specialists also replace gaskets, rings, and seals (the reason is simple – rubber hardens affected by temperature and becomes less flexible; eventually, it leads to oil leakages. Long-term usage of the car with worn friction clutches and rings leads to overheating of pistons and their consequent replacement. Acceleration from rest with the cold CVT (in winter time) leads to curving of the CVT belt on cones (on minimum radius). At the same time, the belt touches cones on the minimum area. It often leads to the belt slippage (with cold ATF). In this case, the belt wears down and scratches cones. With time surfaces of cones will have tears. The belt slippage also will have a negative impact on solenoid-operated valves.
