need info on 03 47re
 

Looking at 500 hp goal. See my trans wasnt a 48re but a 47re my trucks an early 2003. Now is there any difference between my old 96 47 i had fully built n this 47? :humm:

The insides should be the same for the most part. I think the main difference is the electronics are all different on the trans itself.

So id have to do a full build on it like i did before? Great. I thought it had 48 but i was wrong:argh:

Can i change out the 47 for a 48 or do i have to get a new computer and harness?
