Gear Vendors, Inc., manufacturers of the popular UNDER/OVERDRIVE brand of auxiliary transmissions has announced the availability of their new T-10 Manual Transmission kits. Chosen at SEMA as one of the best new Street-Performance products (runner-up), the kits make it possible to adapt a Gear Vendors unit for use on the ever popular T-10 trans. The Gear Vendors UNDER/OVERDRIVE is a 2-speed planetary gearbox that bolts to the vehicle's existing transmission allowing the driver a direct drive (1:1) or overdrive (1:1.286) option in any gear, at any moment. With manual transmission applications such as the T-10, not only does the Gear Vendors add a fifth gear of overdrive to your classic muscle car transmission, its gear splitting capabilities enables you to make full throttle, clutchless shifts into overdrive. Kits are also available for Muncie M20/21/22, Ford Top Loader, and Mopar 833 four speed manual transmissions. If you are tired of being beaten by automatics, this is the solution. You can now have the thrill of driving your muscle car with its authentic, original manual transmission and the added ease and quickness of clutchless shifting as well as increased fuel economy and a more pleasurable highway cruising experience. A race proven winner in CORR, the Paris-Drakar Rally, Baja 1000, Bonneville, and NHRA, all Gear Vendors come with an unconditional 30 day money back guarantee and limited two year warranty for any non-commercial application regardless of horsepower, application, or race usage.
