This just started happening today, when cruising at highway speed it will continually jerk under light throttle as if the torque converter keeps locking/unlocking, transmission shows no signs of issues when accelerating or if I hold the throttle alittle heavier over 2000RPM. It hasn't thrown any codes yet and the transmission fluid is still clean. Not sure if it's related but it started happening after I had used cruise control for about 5 miles, first time I have used cruise control on the car for over a year.
edit: Oh, forgot to mention it's with my daily driver GTP which is mostly stock except the normal boltons.
