My car will move in drive but not in reverse.

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. If your Liberty is moving in drive but not reverse, you may be dealing with an internal transmission problem. The whining sound is likely caused by a broken component, gear, or linkage that is no longer attached. You may also be dealing with a valve body issue, but that is less likely. I recommend not driving the vehicle until you can get it checked out by a trusted shop to prevent further damage. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
