I have a 2011 Chevy Malibu, with a little over 100k miles on it. A couple weeks ago it started acting a little funny when I would shift into reverse after starting it after sitting for a while. I thought it might have been due to temperature as it didn’t do it after the car had warmed up or when it was warmer out.
Yesterday it started acting up really bad, will not shift out of first gear, and will not shift into reverse, and the check engine light came on. I was able to get it up to O’Reilly’s to get the codes. It came back with 2 separate codes.
P0700 - Transmission Control Module (TCM) Requested MIL Illumination
P0776 - Clutch Pressure Control (PC) Solenoid - Stuck Off
The guy there seemed to think that the second code was probably caused by the first one, and most likely the TCM needs replaced. It makes sense to me, but before I head down this path I want to get some input, as it is a little over $300 for the part.
Any help is greatly appreciated!
