my problem: A transmission cooler line broke,dumping atf all over the highway.... had it replaced...drove my truck for a few weeks...diablo tuner says my tranny is slipping.. now it wont shift to 3rd. It just revs and doesn't shift. I need to replace it for sure.

Is replacing a transmission just a matter of unbolting the old one and bolting on the new one?

I would like to attempt this myself because 1. I just want the experience. 2. tired of paying other people to fix my truck only to have if break again.

details:
2000, 5.3, long bed, tow/haul button, auto

Will I need to worry about a torque converter?

Are there any "fun" go fast parts I should consider that are related to the tranny?
