The finest quality Auxiliary Transmissions offer the ultimate in horsepower and performance.
Most auxiliary transmissions are just dual ranges — low gear for towing and high gear for running empty. Gear Vendors Under/Overdrive is built for gear-splitting (giving you a progression of gears with half the drop in rpm) so you maintain power with close ratio performance. Gear Vendors is the only auxiliary transmission that permits shifting under any throttle condition. After it’s installed, your vehicle will have twice as many underdrive ratios plus 3rd-direct and an overdrive gear (3rd-over) for towing. Provides increased engine performance of more than 40 hp and 60 lb. ft. of torque without modification to the engine. The overdrive will pay for itself in fuel mileage alone. In addition, your engine slows down 22%, so the same rpms that currently take you 500 miles will take you 640 miles. Mfr. 2 year warranty for noncommercial use. USA. Special Order.

Excellent Product A Must Have

September 02, 2011
I had a 454 automatic Chevrolet Dully Crew Cab which I used to pull a 20,000# fully loaded farm trailer. I thought the 454 engine would be enough, however on hills it bogged down and used extra fuel. I personally installed a Gear Vendors O/U drive and the hills were no longer a problem. I did not have to down shift from High Gear anymore all I did was flip a switch and the Gear Vendors slipped my vehicle into under drive which is ½ down, not a full gear down when you need just a little more pull, slip the GV O/U down and you have a gear and ½, instead of dropping two full gears. It does all this within a blink of an eye and unlike other overdrives there is no grinding of gears, as it is an automatic. As an Overdrive it gives the vehicle better mpg when shifted into high!
