Ok to get my truck to function properly with the 4l80e I need a file from a truck with the 5.7 and the 4l80e. The 2500, 3500 were both available with this. I got the tranny out of a 3500 dualy with a 350 but the computer was already gone. Might even find this in a tahoe or suburban but im not shure. Help please! Thanks alot!
