Being a 2wd I feel like it would be a simple physical swap for sure. But the tuning is the only issue I worry about. In theory them both being 6 speeds with the exact same hydraulic function it should work if we could suppress the ratio error codes or properly code the new ratios into the tune. I wish it were as simple as selecting 66RFE from the drop down and copying the gear ratios over in those tables. I know I want to give it a try one of these days, I have a customer with a 2012 1500 that just called me interested in giving it a shot today, so we may see sooner rather than later.
Update, the customer's truck is running the 66RFE without ratio error codes. Selected 66RFE in the drop down and changed the ratio parameters to match the 66RFE. A simple slip yoke and conversion u-joint had him moving.
