Plug a scanner that can read all modules/codes into the car's OBD2 port and see if any codes are logged.

That’s exactly what it does. I can shift down with the peddles or the stick itself and it’ll almost instantly start shifting up as high as it can go. If it can hit fifth it’ll shift back into drive by itself as wellSounds like the upshift paddle or the stich sensor is stuck on. Will it downshift wit the paddles? then go right back up?
So I disabled the paddles with the TaZer in the hopes that maybe the paddle was stuck and that’s why it kept up shifting but it still does it despite the paddles being nothing more then fidget toys currently, I think maybe something is wrong with the shifter itselfSounds like the upshift paddle or the stich sensor is stuck on. Will it downshift wit the paddles? then go right back up?
