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. <Ref. to
4AT(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.
• Be wary of the ATF level when filling. If the
ATF is filled to the upper level while the trans-
mission is cold, it is in an overfilled condition
and the oil will overflow.
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. <Ref. to
4AT(diag)-15, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>
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.
