The Super Shift transmission, also marketed as Twin-Stick, was a manual transaxle transmission developed by Mitsubishi Motors in the late 1970s and used in a limited number of the company's road cars, most of which were manufactured in the 1980s. It was unusual in that it had 8 forward speeds in a 4x2 arrangement. It essentially installed a "married" overdrive unit to its manual transmission, something rare in a production vehicle of this type.
