I bought a 2000 4l60e for my 2003 z71. I was just going to put my valve body on it since my shift kit was already in it. But the wiring connectors were different on the EPC and Pressure switch, so I just switched those to my valve body. My question is will this be ok, or do I need to switch to my 2003 harness and switch and EPC. I don't know if it is programmed different or if they are all the same. thanks for any help.

And the tcc from the 00 is still in there.

Thanks

 

It will be fine any way you do it. You just need to make sure that you have a matching epc and harness. Your computer will not know the difference. Vince

 

Thanks Vince.
