A904 has reverse no foward

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.

The springs are interchangeable from any 904/727 valve body so the one from the slant VB will work. The only thing is it might be a weaker spring and not do you any good. You could compare them and see. You could also compare the one from the 727 VB and see which is longer and use the longest one. The 727 valve body is interchangeable except for one thing. The spacer plate dividing the two halves of the valve body needs opened up where the mounting hole is elongated. The lower main valve body half is already open. I don't know why ma Mopar couldn't have also elongated the spacer plate unless it was a ploy to make sure the assemblers didn't get 904 and 727 bodies mixed up.
