The gear vendor overdrive is an auxiliary transmission that works in conjunction with your present automatic transmission. It is built to handle up to 1200 horsepower. It gives you a progression of gears with1/2 the drop in rpm of the stock vehicle so that you stay in the power with close ratio performance. G.M. Callaway Twin Turbo Corvettes with automatics came with a Turbo 400 and a gear vendor overdrive instead of a 700r4 which is the base Corvette transmission.

It has a dashswitch that allows both manual and automatic operation. Most vehicles will experience a mileage increase of 22-28%. The gas it took you to go 500 miles will now get you 640 miles. It pays for itself in fuel savings alone. Most importantly you are getting this horsepower and torque without modification in any way to the engine. No single change to your vehicle can increase mileage and reduce engine wear as effectively, which is why all vehicles today come from the factory with overdrive.

It also lowers exhaust gas and transmission temperatures extending it's life. Can tow up to 30,000lbs. Gear Vendor has been in business for almost 35 years. Over 2 million new vehicles have come factory equipped a gear vendor overdrive. These manufactures include Allegro, Fleetwood, Monaco, Executive and Rexhall motorhomes.

Volvo passenger cars and Ford Diesel Transit vehicles that average  200,000 miles per year. S.E.M.A. awarded it the (Best Engineered Product Award). Just remove the transmission extension housing and bolt on the Gear Vendor replacement housing. See www.gearvendors.com for more information specific to your vehicle. It weighs about 46 lbs. The original cost was $2695.00 plus tax and shipping.   Brand new unit been sitting on the shelf for several years.  Thanks for looking!
