C: INSPECTION
Check all disassembled parts for wear, damage or other problems. Repair or replace the defective parts as
necessary.
CAUTION:
Although the surface layer materials of rubber hoses have excellent weathering resistance, heat re-
sistance and resistance for low temperature brittleness, they are likely to be damaged chemically by
brake fluid, battery electrolyte, engine oil and automatic transmission fluid and their service lives are
to be very shortened. Wipe off hoses immediately if any of these come into contact with the hoses.
Since resistances for heat or low temperature brittleness are gradually declining according to time
accumulation of hot or cold conditions for the hoses and their service lives are shortening accord-
ingly, it is necessary to perform careful inspection frequently when the vehicle is used in hot weather
areas, cold weather areas and a driving condition in which many steering operations are required in
short time.
Particularly continuous work of relief valve over 5 seconds causes to reduce service lives of the hos-
es, the oil pump, the fluid, etc. due to over heat.

A: INSPECTION
CAUTION:
The level of ATF varies with fluid temperature.
Pay attention to the fluid temperature when
checking ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor. 5AT(diag)-15, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D), shift the
select lever in “P” range. Measure the ATF level
with engine idling for one or two minutes.
4) Make sure that ATF level is above the center of
upper and lower marks at “HOT” side.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the fluid level is found above the center be-
tween upper and lower marks.
CAUTION:
•Use care not to exceed the upper limit level.
•Adding ATF to the upper limit mark on “HOT”
side when the ATF temperature is below 70°C
(158°F) will overfilling of ATF, causing a trans-
mission failure.
6) Check ATF level after raising ATF temperature
to 70 — 80°C (158 — 176°F) by running the vehicle
or by idling the engine again.
7) Check the ATF for leaks.
Check for leaks in the transmission. If there are
leaks, it is necessary to repair or replace gasket, oil
seals, plugs or other parts.
B: REPLACEMENT
1. AUTOMATIC TRANSMISSION FLUID
1) Drain the ATF by removing drain plug.
NOTE:
Before starting work, cool off the ATF well.
2) Replace the gasket with new one, and then tight-
en the drain plug to specified torque.
Tightening torque:
20 N·m (2.0 kgf-m, 4.5 ft-lb)
3) Pour in the ATF using the oil charge pipe.
Recommended ATF:
Refer to “RM” section. RECOMMENDED MATERIALS, Recommend-
ed Materials.>
Capacity:
Fill the same amount of ATF when drained.
4) Check the ATF level. TION, Automatic Transmission Fluid.>

2. ATF FILTER
NOTE:
Basically, the ATF filter is maintenance free, but
when it is rusted or physically damaged or leaking,
the ATF filter needs to be replaced.
For the replacement procedure of ATF filter, refer
