 The transmission shifts jerky at low speed. Slow down to 8-10 mph (like at a yield) and press the gas normal and the car will jerk hard as it downshifts from second to first. Think of a young kid learning to drive a clutch. That is the best way to describe this. The bigger problem comes when passing on the freeway. You see a gap and floor it but nothing happens for 3-5 seconds. I think this is because there is no longer a cable from the gas pedal to the engine... it's all done by computer now.  My 99 Camry with 160,000 miles had better throttle response and shifted smoother than this car does!
