I took my Lightning to a local tranny shop about 2 weeks ago to get the convertor out my 99 installed in my 01. While doing that I had them firm up the shifts (accumulator, etc.) and install the 4x4 tranny pan. It's been back there 4 times since for a leak in the tranny where the driveshaft inserts! I brought it home the third time this afternoon, which it looked dry..AGAIN...parked it in the garage. I checked it a few hours later and it's dripping on my pipes again. I had it back there by 5pm. The replaced the driveshaft seal, spring thingy, etc. already This is so frustrating! I don't know what else it could be unless they scarred the end of the driveshaft. Thanks for reading.

 

Eric, you need to have the tailshaft bushing replaced. I used to see this at the dealer all the time. Leaking rear seal? Replace the seal. Except the seals usually leak from the bushing being worn out, or knocked out of posistion from an inproper shaft install. Once the bushing is damaged, the seal will leak every time you replace it. Hope this helps.

 

Thanks for the info Sal, I bet that's what it is. I will call them in the morning.
