MOTORHOME APPLICATION GUIDE
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/Ford 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 more
efficient. 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 only
performance 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 Vendors
because of its performance and engineering reputation as the best in the industry.
Gear Splitting is that ability to give you a gear between
each of your forward gears sequentially. Study the Final Drive Ratio chart for your
transmission (in the 2-wheel drive section of this catalog) and notice how you will
now have 4 underdrive gears, one direct drive gear and one overdrive gear for a total
of 6 forward ratios. Notice also how the close ratios keep your engine in the power
from 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 manufacturer
and 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 means
they are intended to just give you three lower gears or three taller gears but you
still 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 of
this 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 or
answer any questions you have. There is simply no good reason not to own a Gear Vendors
in these vehicles.
4-SPEED AUTOMATIC equipped motorhomes cannot
get better benefit out of a performance device than the Gear VendorsS 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 powerplant 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.)
