Hello,
I need to swap the transmission segments to convert over from a 4L80E to a 4L60E.
Thea reason for this swap is that I couldnt make the ETC work with the original ECM and tried differents TACs, pedals and TBs... none worked.
So, since I am in a hurry, I am just going to use another ECM that came with the original TAC and pedal and works, the problem is the first one was from an 03 Escalade and had a 4L60E tranny and the new one is from an 06 Sierra with the 80E tranny.
How are these segments changed?
Can I just write the calibrtation from the Escalade onto the Sierra?
If I do so, can I still use the TAC and pedal from the Sierra?
I have a couple credits that I just purchased for this, but I do not want to use them if it will not help my issue.
Thanks
Rat Chevelle
