    Just got done converting my truck from a 48re to a NV5600 and after reprogramming the ECM to a manual configuration the truck shows a P2127 code that will not reset. The truck was running just before with the automatic setup with the NV5600 in place an no codes. I have put in a new APPS setting the voltage on pin 3 at .554 volts no change. truck runs and drives great nothing wrong the the throttle. The cruise control is doesn't work, guessing its due to the APPS code.
    Any ideas?
    Thanks

    Yes, have an idea, the manuals use a dedicated different APPS then the Auto Trans. With I guess a different range or ohms. Now that your ECM is converted to Manual it looks for a manual APPS and isn't happy with the values from the Auto.

    That's my guess.

    anyone know where to find the specs on a manual trans TPS?
    or how to program the MM3 so it will work with the automatic TPS?

    I seem to recall that in a conversion to a manual ECM you need to convert to a manual APPS, since that is what the manual program needs to work properly.

    ok, anyone know the pinouts from a automatic trans TPS connector to a manual trans TPS connector? both have 6 pin connectors. Also how does the cruise control work on a manual trans truck?
    thanks
