97' AW4 Starting in 4th gear... have code.

Here's what I have found so far...

66No message from the Transmission Control Module (TCM) to the Powertrain Control Module (PCM)

It drives great when I shift it manually. Oh ya, the backup lights don't work which I have read in other posts has something to do with the NSS. However, fixing that did not fix the shifting problem in previously read posts. Any help?

That means the TCU in not running so it's a fuse or the TCU is bad.

I took the glove box cover off, and found a multi colred wire assembly with a clear connector in the middle of it... ohther than that, I have no idea where the TCU fuse is located and what else needs to be removed to get to it. :dunno:
