After over three years of the Chevelle not running and the guys at Crest not being motivated to help I decided to go pick up all my trans stuff from them and try to put it together myself. Lucky for me I had a spare TH400 with 16,000 miles on it that just needed a new output shaft to work in the Chevelle. So I picked up the spare and my old trans which the old one was in pieces and have started to swap out the output shaft.
I have new clutches and steels but there is no wear on the ones in the spare trans so I don't have to replace them. I'm also installing a new transbrake on it so it will take me a little while to do since I have never worked on an auto trans before and I know nothing about how they work. I do a have a book on the TH400 so hopefully I will be able to complete this on my own.
Here's where it's at right now.
