Transmission roughly jerks itself into 2nd-3rd gear. When the car has come to a stop and is then accelerated, engine stalls for a few seconds, then slams itself into 2nd or 3rd gear. This poses as a rear-end threat, as the car is forcefully put into gear, causing the car to jerk forward suddenly. For me this only occurs at lower speeds (10-30 mph). I have researched this problem and many others have come across the same thing.
