Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** your engine mounts have been replaced then it sounds like your transmission mount is the issue. First remove drive belt to verify you still have vibration if so remove the transmission mount and inspect for debris between the 2 halves of the mount next to the metal rod. Clean all debris and install a 5.5" piece of 3/4 heater hose to prevent foreign debris intrusion into the mount. Here is a bulletin GM released for problem, let me know if you have questions. Thanks.
