Finally got around to rebuilding the transmission on my Suburban Tow rig.
1987 3/4t 2wd TBI 454/TH400 HD 41 case.
The Transmission was fine and had been regularly serviced, and only had one issue...
No L2, or engine braking in 2 as you came down to a stop. If you selected L2 on a hill for engine braking, it just ran away, like you selected neutral.
Scary.
I threw another TH400 I had in a couple of years back, but now that one is bad... Time to rebuild the original and swap it back in.
Ok, so I got a rebuild kit and threw it up on the bench...
Pump and shaft has a little surface rust on...
