Th200 to th350

[Champ2014]

I'm going to be swapping out my weak, old, tired th200 to the th350. This transmission just feels so sloppy and built for the elderly. I originally wanted to put in a 200-4r but ion think this transmission will hold till I can find one and what it takes to do the swap. So I will be putting in a th350 and my biggest 2 questions are what kinda line do I use for the vacuum? And will I notice a difference compared to the th200?

I used 3/16" steel brake line from Oreilly and bent it to follow the frame and a short rubber line at each end for the connections.

Cant help you on the difference in feel. I put mine in with the new V8 so everything changed. Then went to a 700R4 for the extra gear and OD.

Everything was a straight hookup for me in my 87 cutlass. The th350 feels firmer and stronger.
