Hello, I'm new to the forums here and I have an 01 half ton silverado that I want to swap a 4l80e into in the future. I know a stand alone tcm isn't needed to do the swap but my question is, does anyone make a tcm that would let you choose between a full manual or automatic shift mode like the newer 6speed autos in cars? its just a pipe dream I had but I think it would be sweet to have something like that in a truck if its possible.
