I was at the scrap yard yesterday, and picked one up for $20, and THOUGHT it was a TH400. I am OBVIOUSLY not very familiar with GM transmissions. I planned to use the junkyard special for mock up, and then rebuild it when I'm ready to fire up the car. I was just wondering if anyone has used these. I guess they were used in GM rear wheel drive cars with the 3.8 V6, 305 & 350 Olds and 301 pontiac from 1981 to 1989. This is a 4 speed, overdrive unit.
I plan to run it behind a 292 Ford Y Block, in a 'glass 32 roadster, 4.11:1 gearsw/ mini spool in a Ford 8 inch (D/STR). Thanks.
