Gear Vendors Save Gas or Diesel Fuel Extend Motorhome Mileage, Extend Engine Life, Start Saving Money Today!

Does your Motorhome RV need more power to climb hills or tow with heavy loads, plus at the touch of a button taller gearing for cruising down the highway with the lower engine RPM's and improved fuel mileage. Our Gear Vendor overdrive for your Motorhome are available, Our overdrive transmission provides 500 to 600 less RPM's plus 20% increase in fuel economy. You need an auxiliary overdrive transmission capable of gear splitting behind your transmission lower engine RPM means longer engine life. The toughest built best performing auxiliary overdrive transmission you can buy is the Gear Vendor overdrive from Drivetrain Specialist.

Gear Vendor's Complete Kits Ensure a Smooth Installation in Your Motorhome

Gear Vendor overdrive Kits are Complete with Adapters Our Gear Vendors overdrives are supplies with specific adaptation kits for each model of transmission model, the kits are completed. By supplying specific extension housings to each model/brand transfer case GEAR VENDORS is able to have a better product with increased engineering benefit to the final installation. Fact is, when you are in 4X4 there is very little desire to use GearSplitting and overdrive unless you are racing (and we do make the in-between kit for that purpose), it's 2wd where the benefits of overdrive and additional gears are most needed, see YOUTUBE video for more information.  All our kits bolt directly to the rear of the transmission, you can manually control the unit or we suggest you flip switch when leaving city limits sign and turn it off when you get to next city limit sign. No additional crossmembers are required and you retain the factory ground clearance instead of moving the transfer case rearward which puts it at or nearer the middle of the wheelbase where ground clearance is most critical.

Gear Splitting is that ability to give you a gear betweeneach of your forward gears sequentially. Study the Final Drive Ratio chart for yourtransmission (in the 2-wheel drive section of this catalog) and notice how you willnow have 4 underdrive gears, one direct drive gear and one overdrive gear for a totalof 6 forward ratios. Notice also how the close ratios keep your engine in the powerfrom one gear to the next.

This is where the trademark UNDER/OVERDRIVE stems from because the Gear Vendors will give you more performance than any underdrive or overdrive on the market. In fact you could purchase both an underdrive and an overdrive by any other manufacturerand still not have the performance of a Gear Vendors. The only thing an underdrive could do is get you a gear below first, which Gear Vendors cannot, but you gladly trade that for all the performance and engineering of a Gear Vendors.

All other underdrive or overdrives on the market are simply Dual Ranges. This meansthey are intended to just give you three lower gears or three taller gears but youstill have the same space between each gear you have now. This is because all competing units are small manual transmissions whereas the Gear Vendors is designed like your automatic. With other products you could actually go slower than you do now. The Gear Vendors is the only product actually intended to shift through the gears when you need power, under any throttle condition, including full throttle.

Now you will always have the right gear for power and economy. Plus, the Gear Vendors gives you many automatic features with our AUTODRIVE tm control system,which is standard and turns the overdrive on and off automatically just like your vehicle came factory equipped with the system.

Read also the section concerning your transmission in the 2-wheel drive portion ofthis catalog and study the Horsepower and Torque curves in that section as well.Then, simply call us and we will arrange an installation at your local dealer oranswer any questions you have. There is simply no good reason not to own a Gear Vendorsin these vehicles.

4-SPEED AUTOMATIC equipped motorhomes cannot get better benefit out of a performance device than the Gear Vendors UNDER/OVERDRIVE.  When the first of the 4-speed automatic equipped chassis’ debuted in 1990, Fleetwood decided that there was a decided that there was a decided performance advantage to staying with the 3-speed Oshkosh/John Deere chassis and adding the Gear Vendors. So all of the later Fleetwood Limiteds came factory with the Gear Vendors. The performance advantage is because the 4-speed automatics were designed under CAFÉ (Corporate Average Fuel Economy) legislation for the pickup trucks that carried EPA mileage ratings. Because the whole basis of the design was fuel economy of an empty pickup truck not performance of a motorhome, the Torque Converter has a clutch that applies in all gears but 1st. This robs the chassis of the variable ratio and torque multiplication achieved with the earlier fluid coupling designs in the 3-speeds. So, though today’s engines produce far more power you have no doubt noticed that they really do not seem to perform any better on grades and loads.

By installing the Gear Vendors you will really wake up the potential of the engine. Plus you’ll be getting this performance through the best means by attacking the root cause of the problem which is the limited ratios and torque multiplication of the transmission. The Gear Vendors will give you twice as many forward gears that you can shift to under any throttle condition. Unlike any other auxiliary transmission you will be able to go sequentially to gears right between the existing ratios. Study the Final Drive Ratios and Horsepower /Torque curves in the 2-Wheel Drive section for your chassis make. You will have substantial gains in both Horsepower 50+ and Torque 60+ without modification to the engine or transmission.

Since motorhomes are always loaded aerodynamically as well as laden weight, the Gear Vendors is the best way to reasonable power enhancement. Any modifications you do directly to the power plant simply make everything work harder against your continuous load. A Gear Vendors lets you tap into the power of running the engine at the proper rpm with approximately 1/2 the drop from one gear to the next. Plus, since gears are multipliers of torque you now have this better running engine getting its torque multiplied to make it easier on the entire chassis. Because of this, if you have already installed some sort of engine modification the Gear Vendors will help you get the most from it.

Besides climbing grades, when you are towing you will now run in Gear Vendors overdrive ratio with your factory transmission in direct drive 3rd. This gives you much better torque multiplication and lowers your transmission temperatures by as much as 100 degrees on hot days. Also, since the torque multiplication is higher there will be fewer times you need to shift out of overdrive so there is some potential for increased mileage and certainly no cost in mileage. Some chassis’ are equipped with 5.13 or higher rear ends. These chassis’ can make use of double overdrive when conditions are right for even more mileage benefit. The Gear Vendors will also not hunt as some chassis’ are prone to (unlocking and locking under slight throttle changes) when in factory overdrive, as the UNDER/OVERDRIVE communicates with the vehicle control processor so that you get consistent performance.

For people who care about performance and having things work right, the Gear Vendors is just the right product. (you will also find useful information under your brand and transmission in the 2-wheel drive section.)
