I'm getting the Code: U0404 "Invalid Data Received from Gear Shift Control Module" on my 2007 Jeep Grand Cherokee. I read the link here on how to remove it HOW TO: Change out PRND Bezel/Gear Shift
but I had a question.
If a new gear shift module has to be replaced, does it have to be reprogrammed/re-flashed
after it is installed?
I took my jeep to a dealer and had the code read and they quoted me this enormous price for the part/labor and said that I could not buy the part off the internet because it had to be reprogrammed after it was installed. They said I would have to have the jeep hauled in if I installed the Gear shift module myself and have it programed.
My question is, does anyone know if this is true. I can save a ton of money by buying the part and installing the module myself.
Thanks for helping
