The 10 speed transmission in our car shudders and vibrates badly and gets stuck in very high gears. The problem happens most often between 17-23 miles per hour, and is most noticeable on inclines. instead of downshifting to a lower gear at lowers speeds, the car is stuck in 6-7-8 gear. This causes a long hesitation where we are worried we could get rear ended or hit at an intersection. We have been shifting the car manually with the paddle shifters to drop into a lower gear, but this also takes time and causes a delay. We have been to the dealer at least 5 times for this issue and no luck on a repair. the problem has been ongoing for over a year now. Thank You.
