A-904 Performance Rebuild Kit

That is the basic rebuild kit for the 904 trans. so you will have to purchase the shift improver kit seperately. I would suggest a Trans-go kit. They cost a little more and are a little more time consuming to install but are far supperior to all the rest.

As far as all the little parts. That basic kit has far fewer parts than I usually use in a normal rebuild. I also replace all the thrust washers and bushings. If you haven't ever rebuilt a auto trans. I would suggest getting a factory service manual or good transmission manual before even disassembling it. You can get a basic manual cheap from www.bulkpart.com or possibly www.amazon.com or a real good manual that really goes in deep on the Torqueflte transmission is written by Carl Munroe. It's also available from Amazon. Probably find them on E-bay too if you do the E-bay thing.
