Im recent recipient of rebuilt tranny and 4:10 drive from a owner here in MN. Rebuilt about +5 years ago, but maybe only 5000 miles on it. been on a shelf in garage for a few years. Its all in one nice and tide piece so figured just swap it all in one shot
Is there any bench inspection or testing process that should be done prior to swapping it or is that just wasted money. My 73 has about 91k on it an it shifts pretty good well, but pukes up fluid after use, as I understand that may be from the TC.
another question I pose is when the tranny is off are there any seals I can replace while we have access. I seem to leak a little oil from every direction, so its process of elimination to get it removed from the rolling superfund site list
any and all input is appreciated. Does there exist a GMC friendly shop here Minnesota. I wouldn't mind sending them some business.
thanks

Erich,
Do you tow something heavy? I am thinking that 4.10s are pretty low gears. JimK's FD chart shows 3000 RPMs at 60.

I do not know the name, or have any experience with it. But in discussions, someone did mention there is a tranny shop in the twin cities that has rebuilt a few gmc motorhomes trannys. Now I do not know if they installed them, or just rebuilt them on the bench, but having a tranny looked over at a shop and resealed, is not usually that expensive. You just have to find a place willing to do that work, and not be worried about you coming back and blaming them if the tranny is bad after you install it.
I will check around and get the name of that shop.
