What Is Tow Haul Mode and How Does It Work?

Tow haul mode is a special setting found in many trucks and SUVs. It changes how your vehicle’s transmission works. When you’re towing a trailer or carrying a heavy load, this mode is designed to help. It adjusts the shift points of your transmission, keeping the engine in a power band where it can better manage the extra weight. This usually involves holding lower gears longer, which can boost torque and prevent the transmission from constantly shifting up and down while going up hills. It also helps with engine braking to improve the vehicle’s stopping distance.

Knowing the basics of tow haul mode is like learning the rules of a new sport. It’s about knowing how the mode is intended to work. Understanding this gives you a starting point. We’ll then examine how the mode can impact things like your fuel economy. This knowledge will set you up to make smart choices when it comes to towing. You’ll then be able to assess whether or not your use impacts fuel consumption.

Transmission Shift Points: The Engine’s Best Friend

The core function of tow haul mode revolves around modifying transmission shift points. A vehicle’s transmission has a set of gears that change depending on the vehicle’s speed and load. When not towing, the transmission will shift up to higher gears quickly to save fuel. Tow haul mode keeps the transmission in lower gears for longer. This is because lower gears offer more torque. This extra torque assists when carrying a trailer or a heavy load. It also enables better acceleration and helps the engine. The engine braking is enhanced, which helps with control when going down hills.

Enhanced Torque: By holding lower gears, tow haul mode provides more torque, which is the twisting force that helps move the load. This prevents the transmission from constantly shifting, which can be inefficient when towing.
Improved Engine Braking: This mode uses engine braking more effectively. Engine braking happens when the engine helps slow down the vehicle without using the brakes as much.
Preventing Gear Hunting: Tow haul mode stops the transmission from “hunting” for the right gear. Gear hunting is when the transmission constantly shifts up and down.
Better Acceleration: With more power available, acceleration is smoother, especially when merging onto highways or climbing hills.
Reduced Transmission Wear: By reducing the frequency of shifts, this mode helps lessen the wear and tear on the transmission components.

Engine Braking Explained: A Downhill Helper

Engine braking is a very useful feature, especially when carrying a heavy load. It uses the engine to slow down the vehicle. When you take your foot off the accelerator, the engine works against the wheels, providing a braking effect. Tow haul mode enhances engine braking by keeping the transmission in a lower gear. This lets the engine slow the vehicle more effectively without relying heavily on the brakes. This is especially useful when going downhill because it lessens brake fade and keeps the vehicle under control.

How It Works: Engine braking uses the engine’s compression and friction to slow the vehicle. This is distinct from using the brakes, which use friction between brake pads and rotors.
Benefits: Engine braking helps reduce wear on the brakes, improves control when descending, and can prevent brake overheating, which can lead to brake fade.
Tow Haul Mode Integration: Tow haul mode is designed to make engine braking more effective. It does this by keeping the transmission in a lower gear.
Situational Use: Engine braking is most useful when driving downhill or when carrying heavy loads.
Safety: Engine braking helps make driving safer by maintaining control, especially on steep grades.
