A904 has reverse no foward

It's replaceable but I've never found new ones listed. I have several old valve bodies that I've gone through saving good parts from. I can send you one if you need it.

Just so you know, this is just my guess as what the problem could be by the description you gave. No guarantee it'll fix it but by your description of how it acts it's what I'd check first.

Does it matter then if it come out of a non lock up, I know that the v-bodies are different between the two, as I believe that the lock-up has a extra valve( seen the difference on u-tube) I do have an old one that was with the slant-6 I believe is a non lock up, wonder if I can swap spring's, plus I have a 727( I know I should have used but I have got some money in this A-904 now I am slightly regretting it) are the v-bodies interchangeable? also I do not get mad at folks for suggestions, I realize that its hard to type sounds and descriptions over the internet, or even over the phone for that matter, I have guessed myself and even had others help and not have been right, hell last year I had an overheating problem that I spent some money trying to fix, in the end it was the water pump(go figure)plus all the time I have spent pulling and re-installing this trans.I really just appreciate the help and advice this sight gives, I only hope I can help folks as I get a little better myself.
