Finished the TH200 to TH350C swap on Wednesday. After a few short test drives, drove it to work on Thu& Fri. It is a far better driving /shifting trans. I went with a TransGo shift kit and it's great. I have had TH350's in the past that were too harsh on the 1-2 shift, but this one is just crisp enough. The TH200 had a 8-26-92 date on top of it in grease pencil, so I assume it has been out before, still shifted like crap. Very easy swap, I had to reshape the cooler lines a little and fab a 1/4" vacuum line for the modulator($7 at Oreilly's vs $30-ish for a pre-bent from Summit). Kickdown cable fit, but had to be adjusted for function of course. Used the TH350 torque converter bolts. Adjusted column shifter in Neutral-OK.. Speedo cable -OK. Crossmember with Energy Suspension trans mount-OK. I didn't have a flexplate/torque converter cover but found one on a V6-700R4 from an Astro van that fit after I cleared it for the starter.
