I am looking to convert a 2008 4WD trailblazer LT to 2WD. I have a transmission from 2008 2WD envoy with driveshaft. I already know what has to be removed and added. My question is do I have to reprogram the TCM/ ECM.

I have a preprogramed TCM from a 2WD 2009 TBSS. Can I use this TCM if needed?

Tks
