2007 GMC Yukon Stabilitrack error P1825

I got this error message on my 2007 Yukon and was told by the shop that the "transmission solenoid" needed to be replace at a cost of $1300. When I picked up the car, I asked for the part and was given the attached. (Photo included) My invoice stated that they replace a "24238968 Valve assembly". After I got home it occurred to me that there was no way the part given to me (photo attached) was a $600 part and I called to question the repair shop. They said that the part given to me was a mistake and that it really belonged to a 1992 GMC 2500 pickup and that my part had to be turned back in for a "core credit". The part does not look 20 years old and when I researched the issue online regarding 2007 Yukons and stabilitrack errors, I found that a common cause is from what is called an IMS or Internal mode switch, which is part of a wiring harness. When I looked for a photo of the harness, it is nearly identical to the part they gave me. The numbers on the harness given to me are Delphi PA66 with 1530 4835 on one side and 1530 4836 on the other. The round connector is a 13 pin. Obviously, I'm thinking that maybe I was ripped off. Can someone please tell me whether the photo of the attached part is also used in a 1992 GMC 2500 pickup? Is there an easy way to see if that part did come from my car? I need help... Thank you.



Steve Says,

Thanks for using my website. From all of the details that you have given it seems like something is amiss. There are several things that might have happened.

If you give the shop the benefit of the doubt it is possible that they replaced the solenoid as well as the wiring harness and just gave you the harness back. But it doesn't make sense that they would have told you that the harness is from a different vehicle.

Most solenoids are round and have some coils of wire in them. Sometimes they are inside a plastic cover. Most of the time there is no core charge for them because they usually are not worth rebuilding, but it is possible that there was a core charge for it.

Just going by the look of it I don't think that part is from an old pickup. Most wiring harnesses back then did not have the plastic surrounding them. They usually used a round plastic protector for wiring and not the square molded pieces. I think this part is probably off of your vehicle, or possible just something that they had laying around.

I hope that you didn't get ripped off, but this story definitely seems "fishy" to me. If I were you I would contact the manager and talk with him about it. If he is good at what he does he will listen and work things out with you. If he does not then you can come back to this website and ask a lawyer about your question. You can do that on this page:
