General Description
AUTOMATIC TRANSMISSION
C: CAUTION
•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Until the oil pan is removed, do not place with the oil pan side facing up to prevent foreign matter from en-
tering the valve body.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, dis-
assembly and replacement.
•When disassembling the case and other light alloy parts, disassemble them by slightly tapping with a plas-
tic hammer. Do not pry apart with screwdrivers or other tools.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Use SUBARU genuine gear oil, grease or the equivalent. Do not mix them with that of another grade or
from other manufacturers.
•Be sure to tighten bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Apply gear oil onto sliding or revolution surfaces before installation.
•Replace deformed or damaged snap rings with new parts.
•Before installing O-rings or oil seals, apply sufficient amount of ATF fluid to avoid damage and deforma-
tion.
•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 cloth
between the part and the vise.
•Avoid damaging the mating surface of the case.
•Before applying liquid gasket, completely remove the old seal.

ning or after idling for a long time, the differen-
tial gear oil will be hot. Be careful not to burn
yourself.
•Be careful not to spill the differential gear oil

C: INSPECTION
Repair or replace any faulty hoses, pipes, clips,
and washers found in the inspection below.
1) Check for ATF leaks in joints between the trans-
mission, radiator, pipes, and hoses.
2) Check clips for deformation.
3) Lightly bend the hose and check for cracks in the
surface or other damages.
4) Pinch the hose with your fingers and check for
poor elasticity. Also check for poor elasticity in the
parts where the clip was installed by pressing with
your fingernail.
