I have a spare transmission for my truck sitting in my shop. I like to tinker, learn things, and work on my own stuff. I've been thinking about rebuilding this trans with new clutches, shift kit, and a gogo solenoid. I've never rebuilt an automatic before but consider myself pretty handy. Money isn't really the problem, I just want to learn how to do it. If I take my time and not get in a hurry, is it a good idea to attempt this myself?
