VR Commodore Gearbox Issues
Phoenix Mechanical
Soaring

Code 68 - The VR automatic transmission has a common issue of setting code 68 PCM fault (transmission slip), due to oversensitive calibration of the memcal. Not all VR's received the revised memcal to eliminate this problem, only those that reported it as a problem. Revised memcal calibrations are available.

Gear Lever noise (manual) - Gear noise may be transfered to the gear lever while driving, or during gear changes. Revised gear levers were introduced which had a softer dampener.

Torque converter - VR 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.
