Any issues? New motor old PCM I'm swapping my 250k+ mi 5.3 out of my truck, My dad's got an LM7 out of an '06 Avalanche with less than 100k on it. Would I have any issues running this motor with my 4896 PCM? Would I need to swap all of the sensors and could, etc. over to the new motor? Or how would it work, (if possible)? Would My 4896 PCM have to be unlocked for any VIN? This is my first time doing this so any help is appreciated!
if the motor coming out is a 00 5.3 and the new one is an 06 then no your going to have to deal with converting from a 58 (new engine) to a 24 (old engine/ current pcm) reluctor.

or you can use this. Might I suggest swapping the cam as well since the LM7 had the weakest cam ever put in an LS.

No 06 was a transition yr. Thats why some tbss ls2 in 06 are 24 tooth. In 07 everything was 58.
Just look at the crank sensor color. If its black its a 24. Grey is 58. Your ecm shouldnt have any issues running it. The knock sensors may be on the side of the block tho. If it is thin u can buy a converion harness. Also limgenfelter sells a 58 to 24 conversion box. So it can be done either way if u want.
