With an Allison Automatic, you can achieve an optimum level of fuel economy and performance. Our transmissions select the optimum shift points based on load and terrain to automatically enhance fuel savings or add more power when needed. In economy mode, the transmission shifts at lower engine speeds to provide fuel savings and upshifts at higher speeds for greater acceleration when required by the vehicle load and road conditions.

Allison’s Continuous Power Technology™ allows our fully automatic transmissions to simply and smoothly deliver uninterrupted engine power to the wheels, letting the driver focus on handling and maneuvering the vehicle. With an Allison Automatic, there are no hesitations or jerks during gearshifts. The smooth acceleration allows vehicle operation to be easy and stress free while keeping your load protected. The ease of operating your vehicle and the increased safety will be evident – inching will be simple, and rollbacks a distant memory.

Tractor_Slider_Reliability

Allison fully automatic transmissions have a global reputation for quality, reliability and durability because we engineer and build them to last. That’s why Allison Automatic-equipped vehicles have been shown to cost less to operate than comparable competitively-equipped vehicles.

Tractor_Slider_Maintenance_UK

Allison makes transmission care easy and less costly. Since Allison Automatics don’t have a starting clutch, you won’t have routine clutch damage or need replacements – a major cost and downtime concern with manual and automated manual transmissions (AMTs). And with an Allison Automatic, you’ll experience reduced brake wear as a result of the integral retarder.

Routine oil and filter changes are the only regular maintenance required with an Allison Automatic. And if ever needed, our global network of authorized service locations will provide you with the Allison service you expect.
