My wifes grand cherokee thru a dtc and I scanned it, it was U0404. Invalid data from control module gear shift. Does anyone know exactly what this means? Is there a different scan tool for the transmission control unit that I can buy? Or does anyone know of a site that lists codes and solutions? My scanner is th Actron Cp9145.


Thanks

depending on your mileage, it may be under warranty

So im told the Grand needs a new shifter bezel assembly, and its not covered under my warranty. Quoted $369 parts and labor. The warranty says it covers "Transmission: (Automatic and Manual) All internal componets,. The following parts are also covered: tourque converter, electronic control units, oil cooler, tranmission mounts, seals and gaskets. Note: transmission case housing, and oil pans are only covered if damaged by the failure of an internal transmission part." Is a shifter bezel not a electronic control unit or a part thereof? What do i exactly have to do to fix this?

Thanks

If you have a binding or broken upper bezel, or a concern with the electronic shifter module (ESM), It is no longer necessary to replace the complete transmission shifter as an assembly. Please refer to Service Bulletin 21-016-06 issued July 2006 that provides a serviceable top PRND bezel part numbers for the shifter assembly. The ESM comes with this bezel assembly. as per the tsb....
