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 to 80%C (158 to
176%F) on Subaru Select Monitor. <Ref. to 5AT(di-
ag)-16, READ CURRENT DATA, OPERATION,
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. Measure the ATF level
with engine idling for one or two minutes.

4) Make sure that ATF level is above the center be-
tween 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 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 to 80%C (158 to
176%F) on Subaru Select Monitor. <Ref. to 5AT(di-
ag)-16, READ CURRENT DATA, OPERATION,
Subaru Select Monitor.>
7) Check the ATF for leaks.
Visually check for leaks in the transmission. If there
are leaks, replace the gasket, oil seals, plugs or
other parts.
