Q: Motor mount replacement

asked by on

I changed my motor mounts and transmission mount with new ones now my car is vibrating very loud when my car is stopped. Do you know what could be the problem?

My car has 202000 miles.
My car has an automatic transmission.

When motor mounts are installed on some vehicles they will need to be neutralized after installation. They may be in a bind and need to be loosened and then engine rocked back and forth to neutralize the mounts from being bound up and then re-tightened.
