The RPO MN6 manual transmission no-cost option for 1989 was a new six-speed designed jointly by Zahnradfabrik Friedrichshafen (ZF) and Chevrolet and built by ZF in Germany. A computer-aided gear selection (CAGS) feature bypassed second and third gears (and locked out fifth and sixth) for improved fuel economy in specific non-performance conditions. The new transmission senses the position of the throttle and only allowed shiftrs from first to second if the throttle was minimal, it would block second gear and only allow a shift to fourth. This was one of the ways that were used tog et fuel economy higher.
The Corvette Challenge race series terminated at the end of the 1989 season. For 1989, the Corvette assembly plant at Bowling Green built sixty Challenge cars with standard engines. Meanwhile, CPC Flint Engine built special, higher horsepower engines that were whipped to the Milford Proving Grounds for storage, then to Specialized Vehicles Inc. (SVI), Troy, Michigan, where they were equalized for power output and sealed. Bowling Green sent thirty cars to Powell Development America, Wixom, Michigan, where the roll cages and safety equipment were installed and the engines from SVO were switched with the original engines. At the end of the season, Chevrolet returned the original numbers-matching engines to each racer.
