You could use a 1999-2002 PCM from a 6.0L equipped truck with 4L80E =
trans and retune from there. Let me know if you need some help...sounds =
like a wild project.

  Subject: [Diy_efi] 4L80E Questions

  Hello All, This is my first post, I have a 2001 4L80E that is in great =
shape, but we are going to build it up anyways to handle more power. I =
am going to install this in my '98 Trans Am in place of my 6 speed =
manual that is in it now, I have reservations about the 6 speed holding =
up to 800 hp/trq from my twin turbo 400 cu in(6.0L iron block based) LS1 =
motor, I have a couple of options to make this work and need some help. =
Option #1) I do have a TCM and wiring harness from a 92 Chevy Diesel - =
SRVC # 16147609 w/ matching wiring harness - I don't have a clue who =
could nail the chip burn on this for me and modify the harness to only =
use what I need, so if anyone knows who can do all this let me know. =
Option #2 Not the most refined but for sure the easiest way is to put a =
manual valve body in it and shift it manually but I would lose the lock =
up feature and might not be as streetable when off the race track. =
Option #3 Sell this TCM and harness and buy an aftermarket TCI trans =
controller, the only down side is the higher $$, so let me know what you =
think I'de welcome all suggestions and input, Thanks Dave=20
