2009 swap ECM - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1 have a couple of trucks that are equipped the same. 2009 1500wt with 5.3l engines. one of the trucks has the speed limiter adjusted to 89 kph (55mph) and it is getting to be a problem as at that speed the truck won't shift into a higher gear.

I would like to swap the ECM's between the trucks and I'm having problems identifying the procedures for 2007+ trucks.

I would appreciate any assistance on this.
