I had four transmissions put in within 3 months time. Three of them were rebuild by so called local transmission professional shop and all failed within a week. The fourth and last one were done by a different shop and found the third transmission with defective and wrong parts in it. Luckily I had help in removing and installing those first three transmissions but not counting the tools and transmission fluids and labor. From my experiences through this nightmare, shops do not completely rebuilds transmission 100% unless we are talking into the 3000 -4500 price range. Those 700-1200.00 cash and carry units lucky 40% or less of parts are replaced as long as they don't show wear on the used parts they'll put them back in even without cleaning especially on the hard parts like direct, forward, reverse drums, fluid pump, center support seals, thrust washers and etc (found this out the hard way). Most of them will replace only the bands, couple of seals and that's about it. I actually saw one mechanic did a rebuild with the corner of my eyes and he uses 20% of parts from a rebuild kit and tossed the almost full package to the only of his shop into a barrel. They do not even disassemble drums to check sprags or springs at all like Glacier does on his diary, it hardly exist and they don't have the tools to do it on these low end shops. Are you sure you don't want to rebuild it yourself?
