6.0 to 4.8 Swap
I want to put a 4.8 out of an 01 1500 2wd into a 99 2500 4wd. They both have throttle cables, so I dont see that being any problem. What about the ECM. Can it be reflashed to work. Will there be any difference in the trans bolt pattern. Just trying to see what problems I might run into.

They are basically the same block, should fit without any trouble.
The 4.8 uses a 4L60 trans, the 6.0 probably uses the 4L80 trans. I think the bolt patterns are the same, but not positive.
If you can, grab the PCM that was with the 4.8Ray
