When driving the vehicle and going from 2rd to 3rd gear (approximately 20-30mph and 2000 rpm) the vehicle will shudder and shake. The problem is consistent. When driving the vehicle, the shakiness of the vehicle slows down acceleration and causes the car to swerve a little. No warning lights come on when this happens. The car has been checked by my mechanic who I have been using for over 30 years.
