Well just a little while ago I was driving and tranny done all sorts of noise and then check eng light. Got home no reverse. Ran the codes only got a P0700 code. P0700 (Trans Control System Malfunction) Ok so what does this actually mean?

Does my NSBU need replacing and will it fix it?

Do you have anything to clear the codes? If so check all your connections to the TCM (Drivers side mounted to the fan shroud) and connection on the drivers side on the trans where the main connector connects to the trans from the TCM. Then start it and see if the codes come back and if you have reverse. I had VERY similar conditions once and it was simply a bad connection to the trans. Might want to spray it with electrical cleaner as well.

Might not be your issue but I always start with the simple stuff when trouble shooting to save a big bill from the dealer. :)

I got the codes cleared. It drove fine yesterday evening. Didnt go very far but fine. Guess that it just went into limp mode.
