    2014 Silverado 1500 4.3 V6 Manual swap questions

    Long time lurker, first time poster! lol. Just did a T56 swap on a 2014. Thought we had beat the system by keeping the trans computer plugged in. Truck starts up and drives fine...up to 4k rpms. Assuming this is what the limit for the computer thinking it is in park. Tried switching the ecu over to manual transmission in the tune file, same thing. Anyone have ideas to try next?

    Reprogram the ecm outside of HPT (AC Delco TDS) for a manual transmission vehicle.
