FORD 3-Speed Automatic Truck/Motorhome
With the GEAR VENDORS dashswitch in “auto” you will have automatic overdrive just like the vehicle came with a factory system. 28% faster cruising gear nets a typical 22-28% improvement in fuel mileage. The GEAR VENDORS will shift on and off without attention of the driver and can be used while towing up to combined weights of 30,000 lbs. An interactive floorswitch is positioned for the left foot (just like a headlight dimmer) to give manual control at any moment so that you can turn the overdrive on/off for performance gear-splitting on grades. A red and green light in the dashswitch indicates the overdrive operation.
Performance while accelerating or climbing grades is greatly improved by the availability of 6 forward ratios (see Final Drive Ratios). With approximately Â½ the drop in engine rpm on each gear change and the ability to downshift at Â½ gear intervals much sooner than with the stock only transmission performance gains of over 40+ horsepower and 50lb ft of torque are typically minimum, see Horsepower and Torque curves.
Most importantly you are getting this horsepower and torque without modification in any way to the engine. Any other way of increasing power (chips, induction, exhaust, fuel) all put stresses beyond the original equipment. With the GEAR VENDORS UNDER/OVERDRIVE™ you get this power because gears are multipliers of torque, plus the engine can be kept in a narrower (better performing) rpm range when power is needed. For this reason if you do have performance modifications the GEAR VENDORS also helps them work to their maximum potential. Not only do you get performance without engine modification but the overdrive will pay for itself in fuel mileage alone. Add to this the reduced wear you get from slowing the engine down so that the same rpms that currently take you only 500 miles will now take you 640 miles.
Most vehicles will experience a mileage increase greater than 22 percent if driven at the same top speed as they are without the GEAR VENDORS. Increased mileage and reduced engine wear is why all vehicles today come factory with overdrive.
The GEAR VENDORS UNDER/OVERDRIVE™ will do more for this vehicle than any Underdrive or Overdrive on the market. You will get all the features normally associated with an underdrive except a gear below first, plus all the economy of overdrive because GEAR VENDORS is the only product you can shift under any throttle condition. The GEAR VENDORS comes with the best warranties in the industry (2 years for noncommercial use) including a 30 day money back guarantee (see Warranty for details) so you know you will be happy with everything about how the GEAR VENDORS installs, drives, and operates. There is no room here to discuss the numerous benefits and situations that arise where additional gears and torque multiplication make dramatic improvements, so call us about your application. From endurance and championship off road racing to factory fitments by quality manufacturers like Oshkosh and Fleetwood, the C6/Gear Vendors is a proven winner and the best auxiliary transmission you can buy.
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.
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.
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 2year unlimited mileage, unlimited horsepower, unlimited abuse warranty plus a 30 days money back guarantee so you know you will be happy about everything from how it installs, performs, and drives.
Fords installs of our product are the easiest there is to define. Virtually every Ford car 1964 and newer you simply bolt us on without any mods to the tunnel etc. Calls us for all the details. The Gear Vendors is not just the best overdrive you can put in your Ford muscle car or restoration – it represents a tremendous gain in performance, mileage, and fun factor, with higher hp handling than any other overdrive available and installs in just a Saturday morning with regular hand tools.
FORD FINAL DRIVE RATIOS
Find your transmission and rear gear multiplier below. The Final Drive Ratio shows you how many times the engine turns for one complete turn of the tires. This Final Drive number is also your torque multiplier when in that gear. GEAR VENDORS reputation for being the best is because of its sophisticated planetary construction. This means GEAR VENDORS is the only auxiliary intended as a GearSplitter behind automatics and the nicest to work behind both automatics and manuals. You are able to shift half gears that keep the engine in the power. Any auxiliary that requires you to lift off the accelerator or is not intended to shift frequently is not going to give you this performance.
There is not room here to cover all the details so call the factory to discuss the full benefits demonstrated on these charts.
