I have a 2000 z71 1500 with the 4l60e tranny autotrac transfer case and wanting to convert to a 4l80e can i get the nv263 electric shift t-case out of a 2500HD silv to bolt up to the 4l80e along with what needs to be converted to make the non autotrac case work work in my truck?

 

As far as I know, you just need the harness, TCCM, and switch. Swap it all out together and you should be fine.

 

Is the harness pigtail connector different on the 263 transfer case vs. the autotrac case?
