1990 GMC Rally Wagon 2500 Q&A
1990 GMC Rally Wagon 2500 Question: Where and how to replace transmission pump seal?
its more than just the seal. if it is leaking, you will need to replace the seal, the bushing inside the front pump, which made the seal leak, and possibily the converter if it is scored. USED PARTS WILL NOT WORK. you need to do it right. Roy - mastertech6371
