There used to be info on Sloppy Mechanics Wiki on how to do that with a 4L80E but I don't see it there since Google changed everything. I know it can be done but you will have to have something like HP tuners to be able to make any changes. If you but an aftermarket trans controller you don't have to have tuning software.
