"jerks"?

One classic symptom is when coming to a stop the engine/transmission is still engaged and is still driving the car forward as you brake- then the transmission disengages abruptly causing a pronounced 'stop' since you've been braking hard to counter the forward drive. This kind of jerk is a symptom of the trans not releasing- an issue with the lock up torque converter, or associated sensors actuators.

Being able to PRECISELY describe the 'jerk' would be of benefit when asking here or taking it to a mechanic....
