does anyone know if the TH350C lock up torque converter will work on the THM200r4? :?:

IIRC, the only TC that will swap is the early 700R4. after a couple of years they upgraded the number of splines.

answering my own question, no they don't. The lockup TC for the TH350C has a different sized opening or neck on it (200r4 is smaller and weaker) and the input shaft is about half inch too short on the 200r4.
Also I don't know about everyone else's but my th350 came with a smaller diameter flywheel and TC. :idea:

so...to shorten this long educational lesson, always remember what TC goes with what transmission when your throwing it all in a parts pile. Look at it, study it, maybe even take your picture with it.
