I just flushed out my fluid for the second time within 1000 miles, as a shop used original Mercon viii instead of mercon v, and i had the accumulator spring changed and reflushed with mercon V and the fluid was burnt already. It shifts perfect and i can't make it slip, but i'm looking to put money aside and either buy a 98 tranny and rebuild it with even better internals, or if mine shits to rebuild this one with a high performance tranny kit. I really would like to have a bulletproof 4r70w built up, and then work on the engine after the summer. Anyone here work on transmissions or have a good connection? Depending on what happens here, i might be willing to travel for a week or so.. Theres a ton of ghetto places in miami, but i'd rather pay someone privately with more experience if possible.
