a th 350 is a lot different than a c4...i know, because i have a c4 in my 66 mustang. all tricks and possibilities aside, we now know that the tranny has to be rebuilt. Theres 300 ways to skin a cat, but which one do you prefer? Theres no debates needed about ways to do it, because I think all of you are right, its just a matter of what works on what model. Thank all of you for the info, and my next tranny question will be about my c4, when the 66 is on the road again, as she likes to slip out of gear at the worst times. Thanks again everyone, and I'll keep everyone posted as we tear into it and see whats what in there, lol, truth be told, I will end up frustrated beyond words with it, and have plenty of questions.
