OVERDRIVE SWAP

摘要

Overdrive transmissions were developed early on in the history of the automobile, and were commonplace add-ons to transmissions by the 1930s and 1940s. For some reason, however, during the height of the muscle car era overdrive transmissions were nowhere to be found. We can only speculate cheap fuel had something to do with it,but there are oh so many more benefits than just drastically increased fuel economy, the foremost of which is decreased engine and driveline wear.
