Subaru Outback: 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 engine to raise ATF temperature to 70 - 80ºC (158 - 176ºF) on Subaru Select Monitor. <Ref. to 5AT(diag)-18, Read Current Data.>

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 to 2 minutes.

4) Remove the oil level gauge and wipe it clean.

5) Reinsert the level gauge all the way. Make sure the level gauge is inserted correctly and in the proper orientation.

6) Remove the oil level gauge again and make sure that the ATF level is between upper and lower marks of the HOT side.

7) If the ATF level is below the lower mark, add recommended ATF until the fluid level is between upper and lower marks.

CAUTION:

8) 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:

3) Check the ATF condition. <Ref. to 5AT-30, CONDITION CHECK, Automatic 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)

6) Pour ATF from the oil charge pipe.

Recommended fluid: <Ref. to 5AT-3, HYDRAULIC CONTROL AND LUBRICATION, SPECIFICATION, General Description.>

CAUTION: Be sure to use the recommended or equivalent ATF. Using material except recommended one or substitute would cause trouble.

Capacity: Fill with the same amount of ATF as drained.

Capacity when transmission is overhauled: 9.6 - 10.0 2 (10.1 - 10.6 US qt, 8.4 - 8.8 Imp qt)

7) Check the level and leaks of ATF. <Ref. to 5AT- 29, INSPECTION, Automatic Transmission Fluid.>
