dozer Posted November 17, 2008 Report Share Posted November 17, 2008 (edited) Just off the top of my head you will need a input shaft for the AWD transfer case if AWD, run 2 wires from pin 22 and 23 from the pcm to the tanny for the 2nd speed sensor, 80e flywheel off a 6.0 and re-pin the main tranny harness 65e plug to the 80e plug. I would also flash a drive by wire 6.0 80e tune rather than a segment swap from HPT.

silverado_ss_04 Posted November 17, 2008 Author Report Share Posted November 17, 2008 (edited) so i will need to run 2 wires from pin 22 and 23 for the 2nd speed sensor. re-pin the plug for a 4l80e.

silverado_ss_04 Posted November 18, 2008 Author Report Share Posted November 18, 2008 (edited) just wondering if anyone knows, for hooking up the second speed sensor do i splice into pin 22&23 wires or do i cut them off and hook strait into the pcm with them.
