My 2006 Vibe AUTO gears down when braking on steep hill. The rpms jump a few hundred and you can feel the car making the extra gear down. I used to do this when I had manual cars - never on an automatic.
Here's the REALLY weird part - I recently changed motor mounts (which i believe are defective - car still vibrating a lot and will be redoing them soon) and the the gearing down on steep hills only started AFTER the motor mounts were replaced.
Is this normal? Could the motor mounts be affecting things? (only 2 top mounts were changed).
Thanks!
