Maybe it's the age thing
I was a week from swapping out the tranny and transfer when I found the gov. was bad in my TH350. I was having some pressure problems in third gear. It would just go into neutral like mode while cruising down the road in third. I was stumped as to what the problem was. Someone on this site mentioned the gov. along with the modulator, and a host of other idea's.
For that, I'm forever grateful as I still have the rebuilt tranny siting on the floor collecting dust!
I was planing to try the engine hoist through the passenger door thing through the hump on the floor. I remember lifting it out of the truck when I bought it and it seemed to have a close balance with a strap around the tranny tail and the transfer.
