6.0 swap question

i have an 03 1500 rwd silverado 196k, trans is starting to slip very bad. i can get a 6.0 2500 engine and trans fairly cheap would this be a direct replacement or is it gonna require rewiring?

I'm sure your aware the 2500 has a 4L80 tranny ...your 1500 has the 4L60 ......

if you have some time perhaps a member that has done this swap can help you with this ..


find out what the replacement yr is also ..that can be a factor as well ..

yes i thought i could get the engine/trans together w/ drive shaft and it would bolt up to my rear diff

You need to get your hands on the wiring harnesses and computers.
