Gear Vendors Under/Overdrive FORD 3-Speed Automatic - Muscle Car / Street Rod / Restoration

The Ford C4 and C6 transmissions are two of the best performing, most durable transmission ever built. By adding a Gear Vendors Under/Overdrive to these transmissions you have an unbeatable package far superior to any factory overdrive automatic and with 6 close ratio gears for performance.

With a 28.6% faster cruising gear your 4.10 rear gears will give you the same net rpm as a set of 3.20s (3.55s will cruise like 2.77s - see Final Drive Ratios. Your engine will turn the same revs it does now in 500 miles but take you 640 miles. Fuel economy will jump 22-28% on a normally aspirated engine and even greater on forced induction powerplants.

Ford Under/Overdrive With our dash-switch set on "auto" the car will act just like it came factory with the overdrive (like Gms Callaway Corvettes that came factory with the Th400 Gear Vendors). The unit will shift into overdrive without attention of the driver and you can let the wife or whomever drive the vehicle. When you are behind the wheel and want to experience increased performance you will set the dash-switch to manual. This allows you to turn the overdrive on/off at any moment. Leave the line with our red light displayed in AutoLaunch and the vehicle will shift to 1st-over as the engine revs giving you a torque multiplier much stouter than 2nd ie - a3.55 cars 1st-over ratio of 1.92 and a final drive of 6.81 is more torque than a 4.56 rear gear car has in 2nd. Regardless of your rear gear you have never felt this much bark in your car.

Jim White's, 37 Ford After you are revved up in 1st-over move your shifter to 2nd and hit our button on your shifter (we shift out instantly) and you are in 2nd. After you have revved up hit the button for 2nd over (this again is a much closer ratio than 3rd - higher than 4.00 with a 3.55 rear). The close ratio performance, sound and manual like interaction is an absolute blast to drive but most important you are getting this performance from the most reliable, race proven, overdrive on the planet.

The Gear Vendors comes with a 2 year unlimited mileage, unlimited horsepower, unlimited abuse warranty plus a 30 day money back guarantee so you know you will be happy about everything from how it installs, performs, and drives.
