id
A: INSPECTION
NOTE:
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. <Ref. to
4AT-21, READ CURRENT DATA, OPERATION,
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 the 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.
NOTE:
When the transmission is hot, the level should be
above the center of upper and lower marks, and
when it is cold, the level should be found below the
center of these two marks.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the ATF level is found above the center be-
tween upper and lower marks.
CAUTION:
• Use care not to exceed the upper limit level.
• Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will result in 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) 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 with a new gasket, and then tighten the
ATF drain plug.
Tightening torque:
25 N·m (2.5 kgf-m, 18.1 ft-lb)
4) Lower the vehicle.
5) Pour ATF into the oil charge pipe.
Recommended fluid:
Dexron III type automatic transmission fluid
Capacity:
Fill the same amount of ATF drained from
drain plug hole.
