1957 was also Chevrolet's first offering of a turbine transmission, known as the Turboglide. However, due to its complexity, most automatic tranmissions buyers shunned the Turboglide in favor of the two-speed Powerglide that had been offered since 1950. Manual transmissions were limited to three-speed, column shifted units, though there are rumors that a handful of 1957 Chevrolets left the factory with Corvette 4-speed, floor-shifting transmissions. No concrete documentation exists to back this claim up.
From a numbers standpoint, the '57 Chevy wasn't as popular as General Motors had hoped. Despite its popularity, rival Ford outsold Chevrolet for the 1957 model year for the first time in three decades. However, the 1957 Ford - with the exception of the rare retractible hardtop model - is not nearly as prized by collectors today as the 1957 Chevrolet.
