Broke it. I put a corvette servo in it. Idle, warm up, no leaks. Drive it through the neighborhood, no problems. Get on the main road, all is good. 2 miles out, I get up to a place where I can get to 4th, there is no 4th. So I go to turn around, then find out now I don't have 2nd. Pull over, look underneath, it's pissing fluid. SO yay me. I'm hoping 4th is a fluid pressure issue from something not sealing and not something else I fuckered up.

What do you think happened? Could you see where it was leaking from? Hopefully it's OK.

Looks like I didn't have the snap ring for the servo cover fully seated. Cover was jammed at an angle and pissing fluid.

The seal for the 4th apply piston was pretty messed up. Not sure if it was during assembly or or when the cover went cockeyed under pressure. That explains why I didn't have 4th. I'm assuming loss of 2nd was due to fluid loss since it worked at first.

Don't rush things, take your time. I tried to shave a few minutes off and get things done quickly.
