The average transmission mount replacement cost is between $110 and $500, depending on the car model and labor costs. A transmission mount costs $10 to $250, while labor costs $100 to $250. The good news is that a new transmission mount is often pretty cheap, ranging anywhere from $10 to $100. The bad news is that unless you have a transmission
4th symptom of engine mount failure: Excessive noise. One of the clearest symptoms of engine mount failure or any car problem in general isexcessive engine compartment noise. Whether it's worn out or completely broken, a malfunctioning engine mount creates loud vibrations and noise that even the least experienced driver would recognize.
Vibrations of the Steering Wheel. This is one of the most apparent symptoms of a bad control arm. What happens is that the worn control arm bushings often generate wheel shimmy. The wheel’s vibrations often get more intense when you step on the accelerator but ease out at cruise control speed.

on n57 535d f10. suspect engine mounts need replacing at 97,000. Suggestion above to run smooth running control is not a bad one. You might have a vacuum leak, especially if it’s rough at idle. The 535d mounts are just like the m57 335d mounts and are vacuum actuated. They change their stiffness depending on rpm.
