Construction
Traveling to and from jobsites in the timeliest manner is critical in the construction industry. Maneuvering in tight spaces is equally important. Mixers, dumps and other construction vehicles deliver on all accounts when equipped with Allison Rugged Duty Series fully automatic transmissions.

Load-Based Shift Scheduling (LBSS)
To optimize fuel economy and maintain superior Allison Automatic performance, Allison LBSS automatically selects between Economy and Performance shift schedules based on the vehicle's actual payload and the grade on which it is operating. It has proven to increase fuel economy by up to 5%*.

Prognostics
Allison prognostics allow you to quickly monitor oil life, filter life and transmission health. Prognostics take the guesswork and hassle out of scheduling routine vehicle maintenance to save you time and money while providing maximum protection for the transmission. That means less downtime, lower life-cycle costs and, best of all, greater productivity for your fleet.
Shift Energy Management/Low Range Torque Protection (SEM/LRTP)
SEM/LRTP provides better engine/transmission integration to optimize the entire driveline system. The result is faster, smoother, more consistent shift quality, increased powertrain durability, improved performance and an overall more efficient vehicle operation leading to greater fuel economy. This sophisticated communication between the engine and transmission serves as the foundation for other features.

Power Takeoff
The Allison Rugged Duty Series is equipped with a standard continuous operation power takeoff provision. The 1000/2000 models offer turbine drive openings in the 3 and 9 o’clock position. The 3000/4000 models offer engine driven PTOs. The 3000 openings are side/side in the 4 and 8 o’clock position; top/side in the 1 and 8 o’clock position. The 4000 model openings are in the 1 and 8 o’clock position.
Customer Testimonial
U.S. Concrete operates over 1,500 mixers with a total production capacity of 9 million cubic yards of concrete per year. Allison Automatic is the standard specification for all new trucks. “We call it virtually bulletproof. We just haven’t had any problems, any issues. It has been one of those components that fits our industry very well.”
– Terry Green, U.S. Concrete senior vice president of operations
Startability
Startability is a vehicle's capability to launch and pull a load. Simply put, it's the 'grunt' or 'get-up-and-go' of a truck. Often only 1st gear ratio is used to judge a vehicle's startability. The truth is, one has to consider the engine torque at the required launch rpm and the torque multiplication of the Allison torque converter. Manual and automated manual transmissions have to launch at very low engine rpm in order to prevent damage to the clutch. This means less torque, which is why they have very deep 1st gear ratios to help them overcome their clutch limitations.
An Allison Automatic uses the full torque from the engine and multiplies it with the torque converter. When the 1st gear ratio and rear axle ratio are factored in, an Allison provides greater startability.

- Greater control and engine braking during operation on steep grades
- More maneuverability when operating in confined spaces
- Slow creep capability with high engine speeds
- 17.12 mechanical ratio with effective torque converter multiplied ratio up to 32.5:1.
Smart Controls
Allison Rugged Duty Series automatic transmissions have brains in addition to brawn. Optional electronic control packages provide precisely the performance features you need to get the job done — whatever it may be.
| PTO Request |
PTO integration made simple using the transmission electronic controls. Commands how and when the PTO engages and monitors operating conditions to minimize potential damage and hazards. PTO Request Flyer – 1000/2000 Product Families |
| Auxiliary Function Range Inhibit |
It’s like an extra set of eyes — making sure beds are down and equipment stowed. Avoid unwanted shifts out of Neutral. Integrates with virtually any vocational vehicle component. Auxiliary Function Range Inhibit Flyer |
Automatic
Neutral |
Improves safety, fuel efficiency and productivity. With Automatic Neutral on the Park Brake, the transmission electronic controls know when to command Neutral — automatically. No need for the driver to shift. Automatic Neutral Flyer |
| Range Indicator |
Choose the range. Create a reaction. Range Indicator provides a usable electric signal when the transmission shifts to a chosen range. Range Indicator Flyer |
| Fourth Lockup Pump Mode |
Step-by-step operator inputs control split-shaft operation and automatically shift the transmission to fourth lockup for direct 1:1 drive from the engine. Fourth Lockup Pump Mode Flyer |
