I have replaced my tranny slip seal 2 times with aheavyOEM seal and still can't get the darn thing to quit leaking around the u-joint slip shaft. There is no damage to the tail housing of the tranny. No wear on the driveline slip shaft. If it was worn then I would know that that is the problem and replace it. Is there a seal somewhere else in the tranny tail housing that is letting to much oil get to the slip seal? Any help out there?[:@]

 

Do you have a lift?
