The following information was provided by Allison Transmission.
Allison Transmission is the world’s largest manufacturer of fully-automatic transmissions for medium- and heavy-duty commercial vehicles. Allison transmissions are used in a variety of applications including on-highway trucks (distribution, refuse, construction, fire and emergency), buses (primarily school and transit), motor homes, off-highway vehicles and equipment (primarily energy and mining) and military vehicles (wheeled and tracked). Founded in 1915, the Allison business is headquartered in Indianapolis, IN. Regional headquarters with dedicated support staff are located in China, The Netherlands, Brazil, India and Japan. With a global presence in 80 countries, Allison has approximately 1,400 independent distributor and dealer locations.
Allison fully automatic transmissions fit operating requirements better than other transmissions because they’ve been engineered specifically for the way you work. They utilize Allison’s patented Continuous Power Technology™ to deliver smooth, seamless, full-power shifts, superior acceleration and startability.
Allison 5th Generation Electronic Controls
Allison's 5th Generation controls feature enhanced programming and a brand new bump lever selector design. Embedded in the 5th Generation control module is a new inclinometer, which enhances vehicle productivity and efficiency in stop-start operations. The inclinometer’s precision and responsiveness improve Load Based Shift Scheduling performance as the automatic selection between economy and performance shift schedules is faster and more accurate, resulting in further reductions in fuel consumption.
Allison H 3000 Hybrid for Commercial Vehicles
The new Allison Hybrid H 3000 offers all the inherent benefits of an Allison Automatic, plus the latest in hybrid propulsion technology.
The Allison Hybrid H 3000 features parallel hybrid architecture that supplies blended power from a conventional diesel engine and stored energy from batteries, along with a regenerative braking kinetic energy recovery system. This advanced propulsion package achieves the highest energy efficiency and makes it perfectly suited for vocations with frequent stops and starts.
Fuel savings are projected to be up to 25% depending on vocation and duty cycle. Additionally, because of the H 3000 regenerative braking kinetic energy recovery system, the greater the frequency of starting and stopping, the greater the opportunity to capture energy and save even more fuel. Actual fuel economy for any vehicle on a given duty cycle depends on many factors including terrain and driving style.
Allison Automatics - the Preferred Choice for Natural Gas
Allison Automatics are perfectly suited for natural gas powered vehicles in a wide range of applications because of the inherent benefits of Allison’s patented torque converter technology and full power shifts.
A natural gas engine behaves differently than a diesel. Engine speeds can’t be controlled as quickly and easily as they can on a diesel. When you lift off the throttle, the engine speed takes a finite time to respond, and this response time is longer than that with a diesel.
Allison Automatics, with their full power shift advantages, provide smooth, seamless shifts, which do not require the driver to go to zero throttle, so the slower response time-to-throttle cycles are not an issue. Manuals and automated manuals require the engine to be at zero throttle to shift.
A natural gas engine has a lower level of clutch engagement torque, which means the engine speed must be increased to provide an equivalent clutch engagement torque as a diesel at vehicle launch. An increase in clutch engagement engine speed at launch causes additional clutch slip with a manual or automated manual transmission. This can be tricky for drivers and tough on clutches.
