Removing And Installing Inner Oil Tube: Removal

Defective toroidal sealing rings at inner oil tube let ATF enter the differential, which becomes overfilled, and oil emerges from the vent of the differential.

In general, a removed oil tube should be replaced.

The oil tube must be inserted only with special tool 3381. Otherwise there is a danger of leakage due to bending of the oil tube.

1. Remove hydraulic control unit.
2. Lever out oil tube with a screwdriver.
