For instance, Volvo’s I-Shift system, one of the most well-known in the industry, has become synonymous with automation in truck transmissions. It allows drivers to focus on steering and braking while the system manages the shifting process. According to a recent report, the global market for AMTs in trucks is expected to grow at a compound annual growth rate (CAGR) of over 7% through 2027.

Meanwhile, fully automated transmissions (ATs) are paving the way for self-driving trucks. Companies like Daimler Trucks and Tesla are experimenting with autonomous vehicle technology, which relies on automated transmissions to ensure smooth operation without human intervention. In these systems, the truck’s on-board computer system determines when to shift gears based on the vehicle’s speed, load, and driving conditions.

2. Electric and Hybrid Trucks Drive New Transmission Needs

The growing adoption of electric and hybrid trucks is another game-changing factor in the transmission system market. Traditionally, electric vehicles (EVs) have used single-speed gearboxes due to the nature of electric motors, which provide instant torque across a wide range of speeds. However, with the growing demand for higher performance and range in electric trucks, manufacturers are starting to explore the integration of multi-speed transmission systems to optimize power delivery and efficiency.

Electric truck transmissions are different from their internal combustion counterparts, requiring advanced gear reduction systems and specialized components. For instance, Tesla’s semi-truck, the Tesla Semi, uses a multi-speed transmission system designed to handle high torque at low speeds while also achieving high cruising speeds on highways. This development marks a shift in how electric trucks are designed and presents new opportunities for transmission manufacturers to innovate.

Similarly, hybrid trucks, which combine traditional combustion engines with electric motors, require transmission systems that can seamlessly manage the flow of power between the two sources. As hybrid technology continues to evolve, manufacturers are focusing on developing transmission solutions that can handle both electric and combustion engine power efficiently.
