Allison M9610AR

The Allison M9610AR is the most powerful and capable fully automatic transmission in the Allison product line, engineered specifically for ultra-heavy-duty vehicles operating under the most extreme conditions. As a variant of the M9610A from the Allison 9000 Series, the M9610AR integrates a hydraulic retarder, providing critical auxiliary braking performance on steep grades, in high-speed descent scenarios, and during prolonged braking cycles — significantly extending service brake life and improving operational safety. Designed to handle input torque levels exceeding 2,400 lb-ft and gross vehicle weights over 200,000 lbs, this transmission is purpose-built for use in military tank transporters, oilfield rigs, mine haulers, and off-road specialty equipment where torque management, reliability, and braking control are paramount. Backed by Allison’s proven electronic controls and adaptive shift technology, the M9610AR delivers seamless power, robust drivetrain protection, and unparalleled performance in demanding field operations.
