Hi fellow JK'ers. Just recently upgraded our JK and absolutely love it! We still have future plans for it but for now we'll keep it as is. Only problem Im having now is after installing the lift kit and 35" tires, the transmission shifts horribly on the highway. Feels like the motor and transmission have a mind of their own. My speedometer is way off too. Anyway, just wondering if anyone has a module or programmer that could help me out with that. I looked into getting one but its sorta out of the budget right now. If anyone can help, I'll supply the brews!
