I replaced all the friction parts except for B2, and the vacuum modulator, all seals , O rings etc. The B2 band almost never needs to be replaced. It is tuff as nails (so the experts say). I purchased a manual from ATSG and a I also used the info from transonline.com and a little advice from a rebuilder near houston. Only needed a 30mm deepwell socket to get the driveshaft nut off. No other special tools were needed. I did use an arbor press a couple of times. After I was done, I took it to Jaggi Import Export
www.jie.com to have it dyno tested ($80). I wanted to be sure that I did it right before putting it back in the car. He said that is worked great, so I was a happy man. He adjusted the modulator pressure and did whatever other adjustments were necessary. He is a real nice guy.
Cost = parts $200, dyno $80, = total of about $300.
I have to say that the feeling of accomplishment is very rewarding and makes it all worth while to me. I had plenty of time and wanted to learn how the automatics work.
