Hi all, in the ,middle of a trans swap for my shop silverado LS1 turbo, from 4l60 to 4l80. the truck has been run for years with the tune but keeps eating transmissions so i have changed harness to 4l80 and fitted 4l80 trans but cannot find a 4l80 file to do a segment swap on. worst case i guess i will have to hand edit every table across to another file . but im stuggling to find a 12225074 4l80 stock file
anyone have a ls1 4l80 base file i can swap injector data, ve tables etc across to ?
