2. Automatic Transmission Fluid
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.
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-
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.
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.
Transmission Fluid.>
4) Tighten the ATF drain plug.
NOTE:
Use a new gasket.
Tightening torque:
20 N·m (2.0 kgf-m, 14.8 ft-lb)
5) Lower the vehicle.
6) Pour ATF from the oil charge pipe.
Specified fluid:
SUBARU ATF (Part No. K0140Y0700)
Recommended fluid:
IDEMITSU ATF HP
CASTROL TRANSMAX J
PENNZOIL QUAKERSTATE • PENNZOIL ATF-
J
NOTE:
Use of the recommended fluid is permitted only in
regions where the specified fluid is not available.
Capacity:
Fill with the same amount of ATF as drained.
Capacity when transmission is overhauled:
9.6 — 10.0 2 ( 1 0 . 1 — 1 0 . 6 U S q t , 8 . 4 — 8 . 8 I m p
qt)
7) Check the level and leaks of ATF.
