um........i wouldn't make it out to be that easy. most guys don't have press, vice, variety of snapring pliers, bearing spliters, vblocks, large bench space, let alone the understanding/knowledege needed to do a successful rebuild. jusk like if some noob goes to rebuild a engine with out any experience. there are many details that if over looked the engine will fail. many that aren't layed out it the tsrm. for instance properly cleaning the bores with motor oil and paper towels till its just clean oil on the bores without any metal dust from honing. the same goes with transmissions.
to the op do some local research. what do other shops have to say about said tranny shops. find one thats busy.
