Then I turned my attention to the transmission. Now, i should say that I eventually will be using a 700R4 but for right now (or if i really like it) im going w/ a TH400. It was cheap to get the trans at a bone yard, and they are alot tougher than a TH350 and built for towing and alot of abuse. I completely rebuilt the 400 w/ TCI parts: pump, clutches-steels, bands, friction plates, valve improver kit, the whole works. I also changed out my output shaft from a 32 spline that comes on the t400 to a 27 spline that normally came on the 350. I got this part as well as an output shaft housing-to- transfer case plate from Raptor transmissions (CA) and this is the finished trans...now i also have a complete disassembly through pics of this trans.
