Transmission general data Jatco CVT RE0F05A (also known as NCVT) is commonly installed on small cars with engines having the capacity up to 1500 cm3. In terms of control, this transmission is fully hydraulic, i.e it includes the block of hydraulic valves like in standard automatic transmissions, but the transmission operation is performed thanks to movement of the main pulley. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type∞CVTFWD1353,23D Fluid N-CVT The main problem of this transmission lies in increase or decrease of the gear ratio, like an emergency mode (2-nd gear). The repair of this transmission should be performed by professionals on a special bench.

Transmission general data 6-speed automatic transmission DSI-6 \ M78LE (M96) was developed in 2008 by specialists of former BTR bureau with a new Chinese owner Geely under a new brand DSI. It is more advanced modification of 6-speed automatic transmission with a longitudinal positioning for 2-liter engines SsangYong Actyon. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATRWD/AWD9,54,5ATF 3292 Technical issues and repair guidelines In many cases vibrations from the worn-out torque converter lead to the damage of the oil pump bearing. The pump with the planetary gear is considered to be a soft spot of 6-speed М78. The planetary gear is damaged by increased torque and vibrations from the torque converter. With regard to electrics solenoids-electric controllers, shifters and solenoids-electric controllers M78 are replaced in this transmission.

Transmission general data The 4-speed automatic transmission BTR M74LE with a longitudinal positioning for RWD vehicles was designed in 1988 by BTR company on commission from a Korean automaker SsangYong for its flagship SUV Korando. In 1989, this RWD transmission was launched in mass-production. In most cases, the M74LE transmission was mated with 2-3-liter engines and found application in RWD SsangYong models - Rexton, Actyon, Korando etc. The 6-speed automatic transmission DSI-6 \ M78LE (M96) was developed in 2008 by specialists of former BTR bureau with a new Chinese owner Geely under a new brand DSI. It is more advanced modification of the 6-speed automatic transmission with a longitudinal positioning paired with the 2-liter engines SsangYong Actyon. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type4ATRWD93,5BTR M74LE Technical issues and repair guidelines In most cases, М74 and М78 transmission models require ATF change and filter replacement during the overhaul. In addition, specialists usually order the pan gasket. For reassembly of М78 (and М74) specialists order the repair kit of gaskets and seals /Overhaul kit and a complete kit of friction components. Brake bands (Intermediate (Direct, High/ Reverse) ) are also considered to be spare parts for this transmission. The rear brake band is replaced in case of burnt fluid and uneven wear-out and the band clearance, in order to exclude kicks in the process of gears shifting.

Transmission general data The 6-speed automatic transmission BTR М11 with east-west positioning was installed on New Actyon (Corando С) in 2010. This transmission was paired with the 2-liter diesel engine having the torque up to 380 Nm. In 2012, after implementation of some changes the М11 unit was modified with introduction of different improvements. This transmission is intended for FWD as well as AWD SUVs. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type6ATFWD/AWD3807,54SsangYong 0578-244021 Technical issues and repair guidelines Typical repair procedures for this transmission include reassembly and replacement of rings, seals, and gaskets (Overhaul kit). In many cases, the whole set of friction components is replaced by repair specialists. The wear-out of frictions leads to clearance increase in clutch packages. Abnormal (increased) clearances in clutch packages (and braking drums) lead to jolts and increase the risk of vibrations under load. Replacement of the brake band with a servo piston is performed in case of vibrations detection in the B1 (555) Drum or shifting with the kick or there is uneven wear-out of servo piston and brake clearance. The necessity to replace of the rear planetary gear in the М11 transmission lies in overloading caused by aggressive driving and neglect of the automatic transmission maintenance services. The oil pump is one of the most popular issues in the M11 unit. This pump breaks down in situations when the overhaul of the transmission and its torque converter is delayed for a long time, consequently leading to extreme vibrations in the torque converter, complicated by contaminated fluid. The piston of the В2 brake package is frequently replaced in this transmission. This piston gets out of order because of overheating and a long-term operation with vibrations. Solenoids are included in the list of commonly replaced spare parts. The M11 transmission design includes 6 VBS solenoids with different holders.

Transmission general data The 6F24 transmission model replaced not very successful M11 model in 2013. This transmission has been installed on Dodge Dart, Jeep Compass, Patriot MK since 2013. In terms of design, this transmission is a copy of the A6MF transmission. For integration of this transmission with SsangYong engines, engineers had to modify electrical part of this transmission, including solenoids and the software. Technical issues and repair guidelines This transmission has the same typical problems as A6MF1 and A6MF2 transmissions. The ATF change should be performed after 80 travelling thousand kilometers, but the fluid condition should be controlled every 20 thousand kilometers. In case of aggressive driving manner it may be necessary to change the fluid earlier. The filter for the 6F24 unit is replaced only with removal of the cover and repair/cleaning of the valve body. Specialists recommend to clean the valve body and replace the filter after 120-140 thousand kilometers (when detecting first signs of improper gears shifting) without waiting for wear-out of solenoids. Transmission specialists repair the torque converter if the fluid becomes very hot and gets rapidly contaminated. Engineers of SsangYong adjusted the valve body operation for 6F24 not very carefully, therefore the torque converter slipping (as in Hyundai) and aggressive driving behavior may lead to the lock-up clutch damage by the torque converter by the end of the car warranty period.

Transmission general data Mercedes in cooperation with Getrag had developed 7-speed DSG (7G-DCT) with a dual clutch by 2012. This transmission is intended for vehicles of А, B, CLA, GLA classes. Mercedes has taken into account the experience of VAG in this field and equipped its DCT with a wet clutch, which can operate withmore powerful engines. This transmission is equipped with an electric oil pump, which is engaged when a quick start is required or in case of the maximum load. Number of gearsTransmission TypeDriveTorque (Nm)ATF (full capacity) LATF (change) LATF type7DCTFWD3507,26236.21 Technical issues and repair guidelines The fluid quality monitoring is the only measure required during the first years of operation of this transmission. After 60-80 thousand kilometers, it is recommended to check the fluid state and change with the filter, if some contamination or smell is detected. Mercedes engineers delicately adjusted the mechanism of gears shifting in this transmission and ATF contamination can significantly change the performance capacity of the dual-clutch mechanism. Therefore 7-DCT has two fine mesh filters: 1. One filter is positioned In the pan – metal-plastic filter with a felt membrane. It is recommended to replace it and change fluid after 100 thousand kilometers. 2. The second filter is placed outside – the filter-cartridge. It should be replaced yearly or after travelling 30-40 thousand kilometers.
