I have a 2015 f150 coyote and 6r80 trans swapped into a 70 f100. Ive got it running and driving but it shifts terribly. First thing I've noticed is the vehicle speed is not reading it always says 0. I checked the the harness and connectors they are fine. My question is.. Is there a setting I can change with hp tuners to get that working. I would think that has to be reading to shift properly.
