This 1951 Chevrolet promotional film THE VELVET GLOVE, promotes the new PowerGlide automatic transmission, first introduced in 1950. The automatic transmission, which removes the friction clutch from the driver's hands, is thoroughly explained through the use of models and a "mechanical hand" in a "velvet glove." The Powerglide is a two-speed automatic transmission designed by General Motors. It was available primarily on Chevrolet from January 1950 through 1973, although some Pontiac models also used this automatic transmission after the fire at the Hydra-Matic factory in 1953. Powerglides were used extensively on Pontiacs produced for the Canadian market with Chevrolet powertrains. When introduced on upper-level Chevrolet models in 1950, the Powerglide represented the first automatic transmission offered in a low-priced automobile; in contrast, Ford did not offer their automatic transmission until 1951, while Plymouth car buyers had to wait until 1954. The transmission was simple and very durable, which satisfied customers.

The 1950, 1951, and 1952 Powerglide transmissions did not automatically shift between low and high (direct drive) which made for very sluggish take-offs and many drivers started in "Low" and shifted to "Drive" at about 30–40 mph (48–64 km/h), which was hard on the transmission. The 1953 and later units when in "Drive" started in low and automatically up shifted to high at a speed determined by the throttle opening. By the mid-1950s, more than half of all new Chevrolets were sold with Powerglide.

This film was made by the Jam Handy Corp., makers of some of the most famous industrial films of the 20th Century.
