    LS3 6L80E Tap shifter not working

    Hello, I am currently having a problem with the TUTD and it sound familiar to some of the problems you guys are having. I have a LS3 with a 6L80E with a lokar shifter. I believe i have everything correct, resistance is good, TUTD settings are correct with Range Active at D6, when i put into drive it reads D6, but when I put it into sport mode the TUTD setting will not pop up in the PRND column. Below I have posted the Tune if you guys could look at it and see if there is maybe something Im missing. I also have a computer out of a stock 2015 Camaro that had tapshift and I unlocked it and that didn't work either.53 truck good idle.hpt
