TF690 Transmission parts, repair guidelines, problems, manuals
Transmission general data
| Number of gears | Transmission Type | Drive | Torque (Nm) | ATF (full capacity) L | ATF (change) L | ATF type |
|---|---|---|---|---|---|---|
| ∞ | CVT | AWD | 350 | 12,5 | 5,6 | SUBARU CVT Oil Lineartronic II |
The CVT transmission version named TF690 (Lineartronic) was designed in 2008 for Subaru Outback with the engine capacity equal to 2.5 liters. The second generation was named as TR580. In 2010, this CVT was tested on Impreza with the engine capacity from 1.6 to 2.0 liters. Starting from 2012, this transmission also found application on other Subaru models. The design of middle class CVTs includes a chain instead of a push belt. This CVT is quite sensitive to the fluid state, its cleanness and temperature. There is a special type of oil for this CVT named as SUBARU CVT Oil Lineartronic II (K0425Y0710).

Technical issues and repair guidelines
The repair kit of gaskets and seals is used to replace rings and gaskets. Rubber rings are replaced when the CVT unit is overheated or if it operates with contaminated fluid (including chips) for a long time. In case when frictions burn to the glue layer, the filter with the mesh is also replaced in the process of the TF690 reassembly. Burnt frictions and Forward steel discs are the first to be replaced. Next on the popularity of the replacement are the metal frictions of the Starter package. The starter pack is responsible for turning the cones on and off when stopping and shifting the lever to the neutral position. Transfer frictions also appear in replacement operations. They are responsible for distribution of torque on rear\front wheel drive.
The TR580 unit has problems with the valve body and a set of solenoids. In previous models these components caused the failure of electrics when the transmission operated with contaminated oil for a long time or under extreme loads and temperatures. When the wear-out of the belt and cones is neglected, then it is necessary to replace the cones. A typical problem with CVT cones in Subaru is related to the input shaft bearing, pressed in the transmission body. This bearing is cranked by vibrations at maximum speeds, and then it breaks.
