Hey all just thinking out loud, my th350 in my lemans is giving up the ghost I think. I can drive it for about 10-15 min it shifts a little hard but it hits all three gears, once its warmed up it however the fun begins, it stays in first till it i lift on the throttle then it catches second. third gear is a crap shoot but I don't expect it to find the gear, once it cools off for the day same story with the shifting. Needless to say its deadlined until resolved. The question, has anyone had success with trans oil additives? if so is it worth a shot just to say i did it before blowing it apart to rebuild? History of the trans is been sitting for a few years, as far as i know its never been messed with, exception of me swapping out the vacuum modulator, fluid is red but a little dark. think snake oil can bandage it till I can get it to a shop?
