Smarter than your average gearbox
No heavy clutch. And no lever to wrestle. I-Shift is also available on all Volvo FMX models with a driven front axle. And has been reinforced for the most challenging terrain. So now you can tackle rough and hilly terrain with the comfort and fuel-efficiency of our most popular transmission.
I-Shift makes driving easier, safer and more comfortable. There’s no heavy clutch, and no stick to wrestle with. Every gear change is perfectly timed. The simplicity of the system reduces driver fatigue, helping you to focus on the road and the traffic around you. And if you do want to change gear manually, the button on the gearstick gives you direct control of the shift.
Save on fuel
I-Shift is designed to save fuel. The internal energy losses are low – lower than on manual gearboxes. But it’s the electronics that really make the difference. If you drive in Economy mode, every gear change is timed precisely, ensuring the engine works at the most efficient rpm.
How it works
I-Shift is based on a "classic" unsynchronised manual gearbox – hence its compact design and low internal losses. The magic happens in the electronic control unit that manages the clutch and shifts. By evaluating information about speed, weight, road grade and torque demand, it applies extreme precision to every shift. The system also communicates with the engine, allowing it to adjust the revs and brakes for best performance.
Reinforced for severe duty applications
If you drive in extremely tough conditions, you will appreciate the reinforced I-Shift. It has been designed exclusively for extremely tough environments and is a standard option in the Australian market. This means that I-Shift is now available for conditions where a manual gearbox or the automatic Powertronic used to be the only options.
Crawl slow, run lean
Can I-Shift with crawler gears really help boost your fuel economy? Sure. Because previously, you often had to be willing to sacrifice fuel economy for startability. But thanks to the crawler gears, we can now specify your truck with a faster rear axle ratio, allowing you to stay on cruising speed at much lower revs when you’re driving on decent roads. This lowers your fuel consumption by up to a couple of percent.
Perfect control in any direction
Low-speed manoeuvring is one of the most challenging aspects of the job. Thanks to a transmission ratio of up to 32:1 (and up to 37:1 in reverse), I-Shift with crawler gears let’s you drive at speeds as low as 0.5-2 km/h. You always have total control, making it easy to park with precision when you’re about to load or unload your cargo, and to avoid accidents that can ruin your day and your productivity.
Say yes to more jobs.
I-Shift with crawler gears adds to the versatility of the truck, letting you use the same truck for a host of different driving conditions and assignments. Drive both on-road and off-road? Need to transport extreme loads? Work at high altitudes? Special low-speed applications? No problem.
The crawler gear module only adds 120 mm to the length and 48 kg to the weight of I-Shift.
