The GM 2-Speed That Became a Drag Racing Legend

In today’s video we look at The GM 2-Speed That Became a Drag Racing Legend — the Chevrolet Powerglide transmission. What started as a mild automatic for grandma’s car in the 1950s went on to dominate drag strips around the world. The Powerglide was simple, tough, and easy to live with. But when racers discovered its consistency and bulletproof design, it became the go-to transmission for bracket racing, Pro Mods, and high-horsepower builds.

Keep watching to see how the GM Powerglide 2-speed transmission went from grocery-getter duty to handling over 2,000 horsepower at the drag strip. We’ll cover the history, the aluminum case upgrade, why racers love the 1.82 and 1.76 gear sets, and how this transmission outlived rivals like the TH400, C6, and Torqueflite 727.
