Gears are multipliers of torque and our Ratio Splitting capability
allows you to shift to a gear with more mechanical advantage than the
next stock gear in automatic transmissions and wide ratio manuals. This
also means engine rpm drops about half what it did without the Gear
Vendors and so rpm is sustained - higher torque and rpm on shift = more
Horsepower. When shifted into overdrive final gear reducing both rpm
and torque to reduce the manufacture of HP when steady cruising to
improve fuel mileage and decreases wear on your engine. Two-year
warranty rated at 30,000 pounds applications for Motorhome,
most beneficial when used in commuters, tow vehicles, 5th wheels and
Motor homes. Our overdrive kits are very complete and are designed for
your specific vehicle, detailed installation instructions are included
in kit, and installation is also available.
Related to fuel economy, performance, and emissions — Gear Vendors
overdrive units include state of the art electronics circuits that keep
your vehicle in the optimum performing gear. Whether you are driving a
older non-computer controlled vehicle or a late model with all the
latest emissions computers our electronics provide the interface to
ensure maximum performance and correct rpm without lugging or over
revving in the wrong gear. The OE factory programming remains intact and
our processor just makes it aware of the actual ratio 1,000 of times
per second. In older vacuum or throttle linkage transmissions the stock
governor on the output shaft instantly slows down the moment the
overdrive shifts and so automatically moves the shift point in any
overdrive gear up by the correct 28.6%. So both electronic and
non-electronic automatic transmissions gain a group of features
including a passing gear or climbing gear that is automatically
available without driver intervention and is at the split between 2nd
and 3rd where you really want it. Need more information on how to save

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 VENDOR MOTORHOME APPLICATION GUIDE, FIND YOUR UNIT
Most Class A’s and Class C’s longer than 30ft have a driveline parking brake. To confirm, look at the rear of your transmission and you should see a drum for the brake shoes. If your vehicle does not have the transmission mounted park brake then your products will be listed in the GM/Dodge/Motorhome 2-wd section.
3-SPEED AUTOMATICS gain excellent performance through gears splitting and economy with overdrive. Motorhomes so greatly need overdrive just to cruise at today’s speeds that the product will pay for itself quite rapidly. The engine and all the engine driven accessories get to slow down 22% when in overdrive. Not only does this mean less wear but also these components (a/c compressor, alternator,transmission, etc.) will rob less power at the reduced rpm so you are simply moreefficient. Mileage improvements in the 20+ percent range are proven in all back to back mileage comparisons done by major magazines.
The Gear Vendors is the finest product for Motorhome performance and is the onlyperformance product ever used as standard equipment by the RV, Truck, and Car manufactures.From Fleetwood Limiteds to GM’s Callaway Corvette, manufacturers have used Gear Vendorsbecause of its performance and engineering reputation as the best in the industry.
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.)
