My car is a 93 Corvette. The shifter shaft seal is leaking very little, but enough to leave a puddle over time. I travel allot so it sits allot.
The exhaust, even if taken out would not allow one of the universal tools to fit to tap the new seal in.
Has anyone seen, have, a Kent Moore tool GM would give, recommend, their techs to use? There has to be a specific tool which allows this seal to be pressed in by means of turning a tool using the selector shaft as a holder.
Thanks in advance.

 

I replaced this seal into a stripped 4L60E case and believe me, it needs to be driven in. This little seal has a rather thick metal body compared to something like a extension housing or pump seal. It also needs to be started straight into the case or it will get damaged (don't ask how I know this).

If you can, drop the exhaust system and lower the back end of the trans to see if this will get you some hammer clearance.

 

I can lower exhaust, but not the transmission. Its a wierd set up on C4 Corvettes. It may be worth it to just find a shop to do it, as they will have that SPX/Kent Moore tool GM uses. I have seen one for Allison transmissions on ebay, and it has knurled handles, that allows you to press it on with the tool via turning it.
