I’m wondering if anyone has any advice. I have a 2008 Range Rover Sport and haven’t had it long. Had no service history so thought I’d get a service done. It went to a Garage for a full service and a gear oil change and filter change. Since I’ve had it back the car doesn’t feel well. She’s shuddering, seems to struggle to change gear, there is a whirring noise whilst trying to change gear. I don’t feel confident driving it. Would anyone have any suggestions on what could have happened would be gratefully received.
