What was Chevrolet's 1968 semi-automatic version of Powerglide called?

Chevrolet’s 1968 semi-automatic version of Powerglide was called Torque-Drive.

Torque-Drive was essentially a Powerglide adapted so the driver manually selected its two forward ratios. Unlike a fully automatic Powerglide, it did not use a vacuum modulator to command the shift. The driver started in Low and moved the selector to High when appropriate, but there was no clutch pedal.

Chevrolet introduced Torque-Drive for the 1968 model year in low-powered versions of the Camaro and Nova. Applications included the Nova’s four-cylinder engine and six-cylinder engines in both the Camaro and Nova. Its low introductory price was intended to make it attractive to buyers who wanted simpler operation than a manual transmission.

The arrangement proved unpopular because it required an extra manual shift while offering little price advantage over a conventional Powerglide. Chevrolet canceled Torque-Drive after 1971. Powerglide itself continued into the early 1970s, while newer three-speed Turbo-Hydramatic transmissions increasingly replaced two-speed automatics.
