4l80 segment swap for '05 Escalade
My neighbor is trying to find out what we need to change in the computer for a 4l80 swap in his 05 escalade. He has HPtuners model year licensing for the 05 escalade, and 03 and 04 silverado/sierra. I just can seem to find out if any of those other OS's are compatible, or if it is possible to just do the segment swap on the '05 file. Any input is appreciated.

You'll need a conversion harness to correct the different pin locations and to add a second serial cable from the transmission to the PCM.You need to modify the crossmember to clear the pan and position the mount higher and further back.You'll the shift cable for a 4L80E to have enough travel to engage all the gears and park.Then a different segment file.

Different model year may be a different pin out.
