    I have a code P0880 on my 2010 that the local dealer had for a week then told me they should not be looking at it because it's to old. I have been unable to find any troubleshooting for this code online. I understand it's a power problem to the TCM. I have checked the fuses and tried another relay but have no change. Transmission still stuck in 3rd gear (limp home mode I guess) Can anyone help me with the location of the TCM? Is it incorporated with the ECM in the engine compartment or is it incorporated with the PCM? If anyone can guide me to troubleshooting or wiring diagrams I would really appreciate it.

    A higher level scanner, a digital volt ohm meter DVOM,
    and a vehicle manual are some of the tools
    that will be needed to troubleshoot a P0880.
    A P0880 will cause the vehicle to go into limp home mode.

    Can be caused by a faulty TCM or ECM
    A start is to check all fuses and relays under load.
    Check schematics to be able to check 12 volts going to TCM

    Sorry, that is all I know.
