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.

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.

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.

NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the ATF 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) Park the vehicle on a level surface.
3) After selecting all positions (P, R, N, D), set the
select lever in “P” range. Idle the engine for 1 or 2
minutes, and measure the ATF level.
4) Make sure that the ATF level is between upper
and lower marks of the HOT side.
5) If the ATF level is below the lower mark, add rec-
ommended ATF until the fluid level is between up-
per and lower marks.
CAUTION:
•Be careful not to exceed the upper level.
•When the transmission is cold, be careful not
to add ATF to the upper level on HOT side.
Overfilling of ATF may cause oil splashing.
6) 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-

7) Check the ATF for leaks.
Visually check for leaks in the transmission. If there
are leaks, replace the gasket, oil seal, plug or other
parts.
B: REPLACEMENT
1) Lift-up the vehicle.
2) Remove the ATF drain plug to drain ATF.
CAUTION:
Directly after the vehicle has been running or
the engine has been long idle running, the ATF
is hot. Be careful not to burn yourself.
3) Check the condition of ATF.

6. Time Lag Test
A: INSPECTION
NOTE:
When the select lever is shifted while the engine is
idling, there will be a certain time elapse or lag be-
fore shock is felt. Using this, check the condition of
forward brake, reverse brake, 1st one-way clutch,
forward one-way clutch and 3rd one-way clutch.
•Perform the test at normal operation fluid tem-
perature of 70 — 80°C (158 — 176°F).
•Be sure to allow a one minute interval between
tests.
•Make three measurements and take the average
value.
1) Fully apply the parking brake.
2) Start the engine.
Check the idle speed (A/C OFF).
3) Shift the select lever from “N” to “D” range. Using
a stop watch, measure the time-lag from shifting
the lever until the shock is felt.
Time-lag
Specification: 1.2 sec. or less
If “N” → “D” time-lag is longer than specification:
•Line pressure too low
•Forward brake worn
•One–way clutch not operating properly
4) In the same manner, measure the time lag of “N”
→ “R”.
Time-lag
Specification: 1.5 sec. or less
If “N” → “R” time lag is longer than specification:
•Line pressure too low
•Reverse brake worn
