Automatic Transmission Fluid: Inspection
CAUTION:
The level of ATF varies with fluid temperature. Pay attention to the ATF temperature when checking ATF level.
- 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 - 80°C (158 - 176°F) on Subaru Select Monitor. < Refer to READ CURRENT DATA , OPERATION, Subaru Select Monitor. >
- Make sure the vehicle is level.
- After selecting all positions (P, R, N, D), shift the select lever in "P" range. Idle the engine for 1 to 2 minutes.
- Remove the oil level gauge and wipe it clean.
- Reinsert the level gauge all the way. Make sure the level gauge is inserted correctly and in the proper orientation.
- Remove the oil level gauge again and make sure that the ATF level is between upper and lower marks of the "HOT" side.
- If the ATF level is below the lower mark, add recommended ATF until the fluid level is between upper and lower marks.CAUTION:
- Be careful not to exceed the upper level limit.
- If ATF is added to the upper limit mark on "HOT" side when the ATF temperature is less than 70°C (158°F), ATF will overfill and cause the oil to spill out.
- Check the ATF for leaks.
Check for leaks in the transmission. If there are leaks, it is necessary to repair or replace gaskets, oil seals, plugs or other parts.
