2nd Gen Non-Engine/Transmission Mechanics Advise Needed

[radar doctor]

I have a 99 Diesel. I am wondering if a 03 Engine and a RE48 Automatic transmission can be installed in the 99 and made to work in that Body? If so What would be the hardest thing to do to make it work???? Would the electronics in the 99 work or would something else have to be done?? Is there anyone out there that could tackle this???Oo. Oo.

I would think you would need the electronics from a 2003. The injection system is totally different on the 2003's. So there wouldn't be any way for the older computer to tell it what to do.

I would guess the engine trans would be a bolt in. The dash would probably be a problem, as the electronics would have to be switched over as well.

I think the transmission would be a problem too because of the electronics. If it has any new tricks like down shifting on cruise to slow down like our LHS does, it would not work correctly with the '99 computer.

Frame ??? I would think you are going to have to modify the fame base on how the 03's are put together.
