VN Commodore Gearbox Issues

Torque converter - VN automatics use a lockup torque converter which acts like a 5th gear (overdrive). Through heat or excessive strain, these converters can distort, which causes driveline vibrations at between 1500 and 1800 rpm. Excessive strain and heat can be caused by heavy towing without a transmission cooler, or by lack of transmission servicing. Replacement is the most common method of repair.

Mount - The gearbox rubber mount is bolted to the transmission housing by 2 Allen head bolts. These bolts work loose, which allows the transmission to move independently of the mount, which can result in driveline vibrations during acceleration. Replacement bolts should be torqued and loctited in place to reduce the chance of recurrence.
