Semi truck automatic transmissions are essentially manual transmissions with a computer that controls when to shift them, unlike regular automatic automobile gearboxes.
MANUAL VS. AUTOMATIC
While many seasoned truck drivers have a strong preference for manual transmissions, particularly because earlier automatic models often struggled with shifting at the right times, the latest generation of automatic transmissions has significantly improved and is now becoming the standard. These modern automatic transmissions surpass their predecessors in performance due to several key advantages over manual transmissions:
Ease of Use: Training new truck drivers becomes much more straightforward when they learn on an automatic semi-truck. The elimination of manual gear shifting reduces the complexity of driving, allowing new drivers to focus more on road awareness and vehicle handling.
Enhanced Safety: Although manual shifting can give drivers a sense of control, automatic transmissions enhance safety by allowing the vehicle to react more promptly to changing conditions and situations. The onboard computer continuously evaluates factors such as speed, engine torque, and vehicle angle, ensuring optimal shifting and reducing the likelihood of human error.
Increased Efficiency: While highly skilled truckers might achieve remarkable fuel efficiency with manual transmissions, automatic transmissions generally offer superior efficiency across the board. The precision of automatic systems in selecting the optimal gear for various driving conditions often results in better fuel economy and reduced wear on the vehicle.
These advancements in automatic transmission technology not only make driving easier and safer but also contribute to more efficient and cost-effective operations for trucking companies.
Why does veteran drivers want to stay with the manual ?
Many veteran truck drivers prefer manual transmissions because they believe it provides them with better control over their vehicle. They feel more confident selecting the gears themselves rather than relying on a computer to make those decisions.
This preference is especially pronounced in challenging conditions, such as icy roads or muddy terrains commonly found at job sites, where they trust their own judgment over that of an automatic system.
However, it is important to note that modern automatic transmissions have significantly advanced. In our experience running a high percentage of automatic trucks in our flatbed carrier fleet, which frequently operates on job sites, we have found these trucks to be highly reliable.
We rarely receive calls for tows due to our automatic trucks getting stuck. This demonstrates that contemporary automatic transmissions are not only capable of handling tough conditions but also provide efficiency and convenience without compromising performance
