has trouble at shift points, when you release the gas, you should feel no engine brake because it is coasting at 40m/h. if your car equips 5 forward speed A/T, it should be engaged at 4th gear or 5th gear after the pedal released. the gear engaged at the time depends on how much the opening of the throttle valve before you release the gas pedal. you feel a jerk at 30m/h when coasting and engine brake indicate the PCM needs to be reprogrammed. I believe that the actual gear is lower than it requires that makes you feel 拖滯.
