What Does the Tow Haul Button Do on a Truck?

Tow haul mode is a feature in many modern trucks that allows the driver to shift the transmission into a special gear. This mode can help a truck driver save fuel and provide better stability when towing or hauling heavy loads.

It also reduces wear on the drivetrain of the truck, increasing its lifespan.

When activated, tow haul mode will cause the transmission to shift gears at lower speeds than it normally would. This helps reduce engine RPMs, which in turn reduces fuel consumption and puts less strain on the drivetrain.

It also improves stability when carrying heavy loads by allowing for smoother acceleration and deceleration.

The tow haul button is usually located on the dashboard of a truck and can be easily accessed by the driver. When pressed, it will activate tow haul mode and cause the transmission to shift gears at lower speeds than it normally would.

How Does Tow Haul Mode Work?

Tow haul mode works by changing several parameters within the transmission system of a truck, including:

  • Gear shifting pattern – When activated, tow haul mode causes the transmission to shift gears at lower speeds than usual.
  • Engine RPMs – Tow haul mode will reduce engine RPMs, which in turn reduces fuel consumption.
  • Drivetrain wear – By reducing engine RPMs, tow haul mode helps reduce wear on the drivetrain of a truck, increasing its lifespan.

Benefits of Using Tow Haul Mode

  • Reduced fuel consumption – Tow Haul Mode helps save fuel by reducing engine RPMs.
  • Improved stability when hauling/towing heavy loads – By causing the transmission to shift gears at lower speeds than usual, tow haul mode provides better stability when carrying heavy loads.

Conclusion

Tow haul mode is an invaluable feature for any truck driver who regularly hauls or tows heavy loads. By providing improved stability when carrying heavy loads as well as reduced fuel consumption, it can help make any trip more efficient and cost-effective. Activating this feature is easy with just one press of a button located on most trucks’ dashboards.
