Tran error codes

jim j · October 28, 2003

New to this forum so I hope my question is acceptable. I've had trucks all my driving life but a few years ago I fianly bought a four door sedan. I can't find another forum like this one so I am posting my question here. Don't mean to offend but if my question is way out of the ballpark for this forum, just say so.

My car suddenly stopped up shifting. Fluid is clean filters were not dirty. I am getting two selenoid error messages on the internal diagnostics of the northstar system

PO29 and PO94. Can this be researched further without tearing into the tranaxle?

Going to need more information to help you out. What year, make, and model is this car? Also, where did you get those codes from? I've looked through the codes and can't find those.

Copdodger,

It is a 95 Cadillac Seville. The codes were for the two shift selenoids inside the tranny. They are handled as a kit by GM so they must have a coomon failure point. I've had them replaced and wilol pick the car up later today.
