I feel my issue may have more to do with the fuel injection system. I’ve noticed the following: while stopped at a red light with car in drive and brake pedal applied, the car gently rocks front to back from engine rpm pulsating; more noticeable when car is cold, a/c is on and especially when slowly releasing the brake pedal. During this stationary time, the transmission is not suspect. It does very lightly buck and hesitate 0 to 20 mph when accelerating though. Annoying!
