In the 1990s, GM Powerglide transmission cases were becoming scarcer and it was becoming apparent that the stock GM cases were starting to be overpowered by the larger engines being built. Dennis consulted with many racers and racing transmission companies and ended up redesigning the Powerglide to be much stronger and better performing. The new case ended up being called the "Superglide" and 2 years later the tooling was completed and production started. It was an instant success and in classes where the Superglide was allowed, virtually every world championship since its introduction has been won by a racer using the case.
