Your source
for RV, heavy duty off-road and overdrive transmissions
-
The
transmissions in most motorhomes, particularly older units, are just not up to the job they
are being asked to do.
-
The
same transmission that was designed for a 3,000# passenger car or pickup is now being asked
to pull a 9,000# to 25,000# motorhome and being used for heavy duty towing applications.
This just doesn't make sense. Something has to give and it is usually the transmission which
is then replaced by one of the same. There are better alternatives.
-
Motorhomes in particular often have restricted cooling in conjunction with the additional
load and heat produced in heavy duty applications. Heat is the biggest enemy of your
transmission.
-
One
way some motorhome manufacturers try to `lighten the load' is with gearing. That
unfortunately leads to excess RPM at cruise speed, increased fuel usage, and increased
engine wear. Think about it. If you could cut your cruise RPM by 1/3 you would see increased
fuel mileage, engine life, and accessory life. A 1/3 decrease in RPM means you go 50%
further for the same number of engine revolutions. Your engine, alternator, power steering,
etc will last up to 50% longer.
This is a work in progress so please bear with us while
we do the research and keep the site up to date.
We ask that you double check the information with other
sources to insure accuracy.
