I am looking a picking up a 2WD 5.3 Colorado (a 2010 or 2011), and I want to swap to a T56 (I have one).
I am certain I can disable any trouble codes related to the removal of the auto, and should be able to correct any idle difference and speedometer calibration without issue...but I'm unsure how to run the reverse lockout. Obviously I don't want to run a 1-4 skip shift solenoid...and I COULD run a relay off the brake light wires for the reverse lockout...but I'd prefer to control it in the PCM based on MPH like it should be.
I'm sure there will also be some DFCO differences...but thats no big deal, and I should be able to figure it out.
Does anyone know if this is possible with HPTuners?
I am alright with writing in a different file from a different vehicle, but I HAVE to be able to keep the Colorado's original VIN number in the PCM for inspection.
