I have a spare 6l80e transmission I am wanting to use in my Ultra4 rig. I currently run an LS3 and 6l80e combo. I pulled the trans and motor after King of the Hammers for a rebuild and now I want to get my spare transmission setup to work with the same e38 ECM that is in the car.
I didn't get a chance to pull the working 6l80e TCM info. But here is the OS info for the spare trans and the E38 ECM.
e38 12617631
t43 24261871
I guess what I am trying to figure out is, can I use the HPT tools to re-write the OS in the T43 to match the E38, or is this process more extensive and requires the TCM to be pulled/sent out?
