Whats the difference between a 13 speed and 18 speed?

A 13 speed has a splitter function which is only active in the high range. You could call it 6a, 6b, 7a 7b etc. An 18 speed also allows you to split the 5 lower gears giving you the original 9 gears times 2. You would very rarely use all 18 gears in every day usage.

What is the advantage of an 18 speed transmission?

It increases the fun factor, increases hill climbing ability at low speeds, can slightly increase mpg in city driving ( stop & go traffic ), you will gain extra reverse gears for a total of 4 vs 3 for an 13spd or 2 for a 10spd, and it will increase the resale value of the truck.

What kind of transmission do 18 wheelers have?

Class eight trucks are typically equipped with 10-, 13-, and 18-speed manual transmissions. Now, I say manual because they do require a clutch and manual shifting, but much like high-performance racing engines, the clutch is only used to get rolling from a standing start.

Why do semi trucks have 18 gears?

18-wheelers can have up to 18 gears These gears are necessary for slowing down and speeding up when hauling heavy weight on different inclines and terrains.

Is a 13 speed transmission better than a 10 speed?

Depends on what your hauling,terrain engine and distance on the fuel mileage. A 10 properly set up will get every bit as good of fuel mileage and pull as fast as a 13. We have both and very seldom split the top side on 13’s. New 13’s usually have a shorter warranty than 10’s do.

How does an 18 speed transmission work?

The 18 speed transmission is laid out in an ‘H’ pattern. The easiest way to become familiar with the 18 speed is to practice shifting in an H pattern. The driver uses second, third, fourth, and fifth, then splits up into high range and then shift the H pattern again for sixth, seventh, eighth and ninth gear.

What kind of transmissions do trucks have?

There are currently three types of commonly available transmissions for Class 6 to 8 trucks: manual, automated manual (AMT) and automatic.

Why do trucks have manual transmissions?

Simply because manual transmissions are still more reliable than Automatic transmissions. Most of the big trucks and heavy vehicles use MT because they have a job to transport and deliver power all the time , they cannot be under loss for using an AT which often requires more maintenance.

Is a 13 speed good for heavy haul?

Hey Danny that thirteen speed is a wonderful transmission, especially when hauling a really heavy load up and down some hills. Don’t let it stress you too badly though. You can actually drive it much like you do a regular ten speed.
