2003 545RFE 4x4 5.7 Transmission Interchangeability?

[Ramzman53]

Hello, does anyone know if my 03 545rfe 4x4 from my 1500 5.7 is interchangeable with other years? I know the 2003 was different compared to 04-05, also would it work with a 4.7, thanks.

It's only different in controlling electronics. The RFE itself is pretty much the same from 1999 to 2010. That includes two and four wheel drive, just a matter of swapping t-case adapter for tailshaft.
