TH125C rebuild (Page 2/2)

Ok, I'm stuck trying to install the shift correction kit. The instructions say to remove the pressure regulator from the valve body, but doesn't tell you how.

I have the Superior brand shift kit, maybe the TransGo has better instructions? Anyone have those? Google didn't help me.

I found out another thing about my trans, it's not the original one, it's a 1987 or later trans and the Fiero is a 1985.

EDIT: Nevermind, I got it... had to remove a roll pin.

UPDATE: Today, I got the bottom pan and side pan sanded and painted. I finished the shift correction kit installation. I took the clutch packs back apart. I found out you're supposed to soak the friction discs beforehand and I didn't. While they were apart I found out you can use thinner steels, so I was able to add another friction to the direct and forward drums. I still need to replace the torque converter seal, but it's going back together.

UPDATE: I have the transmission reassembled. I took last weekend off and went camping. That was part of the delay. This trans rebuild was harder than I thought it would be and took longer than I expected. But, it's done now and I feel confident that it's ready. I replaced the drive chain, intermediate band, sprag, clutch discs, steels, seals, gaskets, pump parts, TV cable, etc. I installed a shift correction kit and put an extra friction disc in the direct clutch pack. Next, I'll mate the engine and trans together on the cradle and get it ready to reinstall.



The old chain had 3/4" of slack and the new chain has 1/4" of slack.
