CONDITION:
Some owners may experience an oil leak that is diagnosed as a right axle oil seal leak at the axle tripot shank.
CAUSE:
This condition may be caused by inadequate seal contact to the axle tripot shank.
CORRECTION:
A revised Right Axle Oil Seal was implemented in production to reduce the potential for axle oil seal leaks and is available for service. The revised
Right Axle Oil Seal extends over the axle tripot shank an additional 2 mm (refer to Figure 1).

When Right Axle Oil Seal replacement is required on any 1992-1994 Hydra-Matic 3T40, 4T60 or 4T60-E transaxle, install the revised Right Axle Oil
Seal listed under "Service Parts Information". The previous Right Axle Oil Seal was blue in color. The revised Right Axle Oil Seal is green.
