Leaking tranny fluid, what seal do I need?

**steiger99** · 10-05-2009, 10:38 AM

I have a 1995 LT1 z28, stock manual transmission 6-speed and I upgraded to the ls1 aluminum driveshaft. I have a pretty good leak coming out of the tranny right where the drive shaft and tranny meet up.

What seal or gasket do I need to replace to stop the leak? If you have a part number and website to buy the seal/gasket, that would be great. Also how difficult would this be to do myself? If there is a site that has a guide to walk me through it, that would be ideal. Thanks for your help as always.

It is just the tailshaft seal. In my haynes manual they call it the extension housing seal.It just pops out with the driveshaft out. It probably got torn when putting in the new driveshaft. You should be able to get it at any auto parts store. When you reinstall the driveshaft just lube it up so you don't damage the seal again.

Also check the shaft (tranny side) for the collar spring from the old seal. Just to make sure it's not still around the shaft. The spring may have popped off causing it to leak. Do'nt wanna leave that in there if it did pop off the old seal..
