Automatic Transmission: General Description: Caution

Wear working clothing, including a cap, protective goggles, and protective shoes during operation.
Remove contamination including dirt and corrosion before removal, installation, and disassembly.
Keep the disassembled parts in order and protect them from dust or dirt.
Until the oil pan is installed, do not place with the oil pan inside facing up to prevent foreign matter from entering the valve body.
Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.
When disassembling the case and other light alloy parts, use a plastic hammer to open the case. Do not pry it apart with a screwdriver or other tool.
Be careful not to burn your hands, because each part on the vehicle is hot after running.
Use SUBARU genuine gear oil, grease etc. or the equivalent. Do not mix gear oil, grease etc. with that of another grade or from other manufacturers.
Be sure to tighten bolts and nuts to the specified torque.
Place shop jacks or safety stands at the specified points.
Apply appropriate gear oil or ATF onto sliding or revolving surfaces before installation.
Replace deformed or otherwise damaged snap rings with new ones.
Before installing O-rings or oil seals, apply sufficient amount of ATF fluid to avoid damage and deformation.
Be careful not to incorrectly install or fail to install O-rings, snap rings and other such parts.
Before securing a part on a vise, place cushioning material such as wood blocks, aluminum plate, or shop cloth between the part and the vise.
Avoid damaging the mating surface of the case.
Before applying sealant, completely remove the old seal.
