Default Seal leak and a question

Hey guys. I have a t56 input shaft seal leak. Anyone have any pointers for me? The tranny is out of the car. Also if anyone has the P/N for the seal that would be great. thanks

I don't know what is most commonly replaced, but here are the other seals I see in the parts list:

12523293 - Seal, Reverse Lockout Solenoid (O Ring)

12523301 - Seal, Reverse Lockout (O Ring)

10117848 - Seal, Main Shaft (Double Lip) or

i recond these trans all the time. when doing this repair it would be adviseable to get the right installers. the front seal is a bitch to install without a installer. i got mine straight from "kent moore" its a "j" tool the dealers use. call this # and check and see if they will sell it to you. shouldnt be much either....800-468-6657 ask them for j39433 (it will also do the mm12 vette trans seals,front and rear)
while your in the trans,check all the teeth on all the syncros and blocker rings with a magnifing glass. look for any burrs ect. teeth should be kind of sharp. rounded corners are not good. and you should install a new steel shift fork...3-4 while your in there. when putting the unit back together,be sure to use a good sealer..g.m. sells it. g.m.s. its called. when cleaning the surfaces,make damm sure you use brake clean! any small amount of grease and it will leak.
good luck

The installer places the seal in the correct position. Without the tool you may be doing the job several times. The seal installs on the inside of the front adapter.

Front adapter? I assume you are talking about the plate with the 8 or so boltsin it, on the front of the t56?

Are there any other gaskets i need to order after i remove the front adapter?

Thanks!
