WT: Are there any benefits/pros that a manual or AMT does still have over the automatic transmission?

MANUAL TRANSMISSION DRIVER

Additionally, power take-off (PTO) cannot be applied on the fly as it can be with an Allison automatic transmission.Īll of this can lead to driver frustration, abuse of the driveline components and reduced productivity. Vehicles with a manual transmission also have reduced maneuverability, difficulty on narrow roads, soft soil, steep grades, or backing into loading docks. While beneficial for the individual, this has an added benefit of addressing the driver shortage problem our industry is facing as well.Īnd, the added cost of the automatic transmission is often significantly less than the cost to the business to recruit, train, and retain a replacement driver.

MANUAL TRANSMISSION DRIVERS

Many drivers have indicated that their careers have been extended by transitioning from a manual to a fully automatic transmission. Fewer drivers are available today who have experience driving a manual transmission. It is also easier to recruit drivers to operate an automatic compared to increased training to drive a manual transmission. Smooth, seamless operation allows the driver to easily maneuver the vehicle so attention can be focused on the job at hand.

With reduced driver fatigue, automatics increase driver retention and provide a more controllable environment for the driver and vehicle. HARBIN: An automatic has the same benefits over manual transmissions in terms of uninterrupted power at every shift, without the physical toll on a driver who has to shift all day or the wear and tear on the manual clutch. WT: What benefits does an automatic transmission have over a fully manual transmission on driver productivity?

MANUAL TRANSMISSION FULL

In the case of a mixer truck, that lost downtime can be as much as $7,500 per truck per day.Īnd, that’s assuming that the barrel wasn’t full when the AMT clutch failure occurred, which would add additional repair cost to replace the barrel.

Many fleets have indicated they can operate a smaller fleet with automatic-equipped trucks, because each truck spends less time being repaired, whether proactively or worst case, reactively. This ensures maximum uptime and productivity for a fleet’s trucks. These interrupts result in more shifts and lower vehicle speeds, requiring more time to do the same job.Īs a second example, fully automatic transmissions eliminate the starting clutch, thereby eliminating truck downtime for required clutch replacements. They also require a reduction of engine throttle at each shift, causing torque interrupts. Unfortunately for those operating AMT-equipped trucks, this is when peak torque is most needed, to get a fully loaded vehicle moving from a stop.ĪMTs do not benefit from engine torque multiplication because they require torque to be controlled or limited at launch to extend the life of the starting clutch. Therefore, AMT-equipped trucks never utilize full engine torque at launch. The full-power shifts provide superior vehicle acceleration, allowing more work to be done in less time.īy comparison, AMTs must cut engine torque at launch to protect the clutch. Among the many advantages, automatics are more productive because they enable faster acceleration than AMTs.Īllison Transmission's torque converter smoothly multiplies engine torque at launch and keeps the transmission continuously connected to the engine's maximum available output during each shift, providing up to 14% faster acceleration. HARBIN: Automatics provide multiple productivity advantages over competitive AMTs. WT: What benefits does an automatic transmission have over an AMT on driver productivity? Without a torque converter, AMTs cannot deliver power to the wheels smoothly, creating more opportunities for inefficient and uncontrolled operation. Drivers can control vehicle speed to smoothly creep with precision, maneuver more easily and have more control on grades – all while protecting the driveline from shock and reducing vehicle wear and tear. A torque converter creates an infinitely variable gear ratio, allowing drivers to easily manage power to the wheels. By comparison, the automatic’s torque converter is not a wear component.īeyond the uptime advantage of the fully automatic transmission, the torque converter provides improved maneuverability in soft/loose soil or where drivers need more control.ĪMTs by comparison typically begin to overheat and will cut power to protect the transmission in soft/loose soil. These power interrupts cost drivers time and lead to higher maintenance costs due to wear and tear on the clutch.
