MALFUNCTION

TEST OR INSPECTION

CORRECTIVE ACTION

1. Loss of fluid from converter.

Step 1.

Inspect for leaky pipe connections.

Check all lines and connections. Be sure no rubbing or excessive vibration

is present. Have system under pressure when looking for leaks by

operating converter at partial speed.

Step 2.

Inspect for leaky converter.

Check all bolts and nuts clamping gasketed joints while system is under

pressure.

Step 3.

Inspect for leakage around output shaft or into lube oil chamber.

This may be caused by a mis-located seal gasket which will not allow the

seal drain to function. The fluid drain holes in the seal assembly and seal

gasket must line up with the drain hole in the housing.

Step 4.

Inspect for leaking fluid into lube oil chamber. This indicates worn charging

pump seal, allowing fluid to leak into the lube oil chamber along the

charging pump shaft.

Step 5.

Inspect for excessive leakage past seals.

This may be indicated by low oil pressure.

a. Low oil pressure may also indicate that filter is clogged.

Replace filter.
