how hard is it to change the front seal on the transmission?
(1) Answer
Front seals usually are signs of other problems. After pulling the transmission, a trained tranmission Mechanic can remove the pump, clean it up & have put back together in about an hour. Make sure to replace the pump bushing & check all the rest of the parts also. Recomend rebuilding the transmission while you have it out. Could save you pulling it out a second time.
