THM200/THM200C 3spd Tech

[MADMIKE]

I believe once upon a time dana @ pro-built offered to put together a performance rebuild(for the 200c) kit for me.

Thanks. I'll look them up. I just recall a website that had bits and pieces for improving the longevity of the 200.

I have yet to se a benfit of any of those trans

It's in the car. It's behind ~140HP of RAW 307 Oldsmobile fury. That and did TH350s have a proper combination of drive/driven speedo gears for a 2.14:1 FD? Without an added reducer/multiplier adapter? I prefer the TV cable adjustment that the TH200 series allows verses the vac modulator. Can get hot/tedious trying to tune the modulator that's under the car and next to the exhaust.



It's not going to be behind a warmed over 455. Just need the trans to work correctly.
