(TH-400) Can you change the shift-linkage seal...
...without dropping the pan? I removed my exhaust today and got a close look at the area surrounding the shift linkage. It appears the seal around the shift shaft is leaking. Don't want to drop the pan (again). Can the seal be accessed/replaced from outside?

Bummer...especially after I poured in a dozen quarts of TrickShift!

We have a small tool at the shop that will remove the shaft seal without dropping the pan. I think it will do 400's. Most tool jobbers (Snap-on, Matco, etc.) carry them on the truck. Better auto parts stores may also have them. G/L

Is it a GM "special tool" or a generic thing that works on different seals?

Probably not worth it to purchase the tool vs. taking it to a shop and having it done.
But, you're right. One can never have enough tools!

I don't have a part number for you, but I can vouch for the tool working. Try an internet search for TH400 shaft seal tool or something along those lines. It should be roughly 35-45 bucks.
