I know the trans line adapters are different, what else has to be changed for the 04 trans to work in an 01? Thanks in advance for your input.

My 02' has a tranny out of a 04' with the g-solenoid valve body in it. I didn't have to do anything different to put it in my truck besides the tranny line fittings.:thumb:

Swap out 01 bell housing and harness,Some 01 bell housings have oddball bolt patterns.just built a 04 trans for my 01 and used the 04 vb with the g syl but the internal harness is different so will have the use the original harness with the newer vb.Swap Works flawless.
