Fluid type explained
The 2022 Subaru Forester is equipped with Subaru's continuously variable transmission (CVT), known as the Lineartronic CVT, specifically the TR580 model. Unlike traditional automatic transmissions that use a set of gears, a CVT uses a steel belt and a pair of variable-width pulleys to provide an infinite range of gear ratios. This design allows the engine to operate at its most efficient RPM for a given driving condition, leading to improved fuel economy and smoother acceleration.
Due to its unique design, the Lineartronic CVT requires a very specific type of transmission fluid. Subaru specifies Subaru CVTF-II for the 2022 Forester. It is critically important to use only this fluid or an approved equivalent that meets the Subaru CVTF-II specification. Using a conventional automatic transmission fluid (ATF) or an incorrect CVT fluid can lead to severe transmission damage, premature wear of the belt and pulleys, and costly repairs. The additives and friction modifiers in CVTF-II are specifically formulated to ensure proper belt grip, prevent slippage, and protect the internal components of the Lineartronic CVT.
Always check your owner's manual for the most up-to-date and accurate fluid specifications for your specific vehicle.
Service procedure
Servicing a CVT is different from servicing a conventional automatic transmission. For the 2022 Subaru Forester, a drain and fill is the most common service procedure. This involves draining the fluid from the transmission pan and refilling it with new fluid to the correct level. Given the complexity of the CVT and the specific fluid requirements, it's generally recommended that this service be performed by a qualified Subaru technician or a shop familiar with Lineartronic CVTs.
