Allison M8610AR Transmission

Allison M8610AR Transmission – Remanufactured

The Allison M8610AR is the pinnacle of heavy-duty automatic transmission technology, engineered for the most extreme vocational and military applications where power, durability, and braking control are non-negotiable.

As a variant of the proven M8610A from the Allison 8000 Series, the “AR” designation adds a powerful integrated hydraulic retarder, delivering exceptional auxiliary braking to support massive loads in steep or prolonged descent conditions.

Designed for vehicles with gross vehicle weights exceeding 150,000 lbs, the M8610AR provides six forward gears, one reverse, and a lock-up torque converter for efficient and smooth high-load performance.

This transmission excels in mission-critical environments including tank transporters, mining equipment, oilfield rigs, and other severe-service platforms that demand reliable drivetrain management and robust braking assistance.
