Replacement of Seals In Car

NOTE: Special tools 5069, 5075, 5117, 5118, 5149, 5241, 5244.

Inspect for leaks. First, check that leakage is not due to high fluid level, i.e. that fluid is being discharged through the vent at top of torque converter housing. Also check oil cooler connections and pressure tapping plugs, which are other possible leakage points.

Transmission Vent:

In event of other leakage: Clean transmission and determine whether or not leakage can be corrected with unit in position.

Torque Converter Housing:

Check leakage from welded joint on torque converter. Insert a piece of paper in opening in bottom of torque converter housing. Idle engine for a few minutes. Examine paper for spots of fluid. No spotting should be present.
