Automatic Transmission Fluid
2. Automatic Transmission Flu-
id
A: INSPECTION
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.
TION, Subaru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D, 3, 2, 1),
set 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 level and lower level at HOT side.
If the ATF level is below the lower level, check for
leaks in the transmission. If there are leaks, it is
necessary to repair or replace gasket, oil seals,
plugs or other parts.
5) If the ATF level is below the center between up-
per level and lower level, add the recommended
ATF until the fluid level is found above the center
between upper level and lower level marks.
CAUTION:
Use care not to exceed the upper level.
Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will overfilling of ATF, causing a transmission
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.
B: REPLACEMENT
1) Lift-up the vehicle.2) Drain the ATF completely.
CAUTION:
Directly after the engine has been running, the
ATF is hot. Be careful not to burn yourself.
3) Replace the gasket with new one, and then tight-
en the drain plug (ATF).
Tightening torque:
25 N
⋅m (2.5 kgf-m, 18.1 ft-lb)
4) Lower the vehicle.
5) Pour ATF from the ATF charge pipe.
Recommended fluid:
DEXRON III type automatic transmission flu-
id
Capacity:
Fill the same amount of ATF drained from
drain plug hole.

Time Lag Test
6. Time Lag Test
A: INSPECTION
NOTE:
If the select lever is shifted while the engine is
idling, there will be a certain time elapse or lag be-
fore the shock can be felt. This is used for checking
the condition of the low clutch, reverse clutch, low &
reverse brake and one-way clutch.
Perform the test at normal operation fluid tem-
perature 70 — 80°C (158 — 176°F).
Be sure to allow a one minute interval between
tests.
Perform measurement for three times and take
the average value.
1) Fully apply the parking brake.
2) Start the engine.
Check the idling speed (A/C OFF).
3) Shift the select lever from “N” to “D” range.
Using a stop watch, measure the time it takes from
shifting the lever until the shock is felt.
Time lag: Less than 1.2 seconds
If “N” → “D” time lag is longer than specified:
Line pressure too low
Low clutch worn
One-way clutch not operating properly
D-ring worn
4) In the same manner, measure the time lag for
“N” → “R”.
Time lag: Less than 1.5 seconds
If “N” → “R” time lag is longer than specified:
Line pressure too low
Reverse clutch worn
Low & reverse brake worn
D-ring worn
