Allison has a long history of partnering with the U.S. Department of Defense to develop propulsion solutions that deliver in the toughest conditions. After initially delivering the first X200™ units in 1960, Allison relaunched production of the transmission in 2020 to meet the U.S. Army’s combat readiness requirements.

Rugged, Fully Automatic Design:

The transmission accommodates engine ratings up to 400 hp (298 kW). It offers four forward and two reverse ranges and full-power hydrostatic steering for smooth, efficient steering and control. The X200™ is equipped with electronic controls for use with modern engines and a torque converter with an automatic lock-up clutch for smooth, efficient starts and stops.

Built to Perform in Combat:

Allison develops transmissions that deliver the unrivaled reliability and durability required for defense applications. Designed for light tracked combat vehicles up to 20 tons, the X200™ features a cross-drive design that integrates steering and braking into one compact and rugged unit.

Allison began production of the X1100™ cross-drive transmission in 1979 for use in the U.S. Army’s M1 main battle tank. After more than 44 years of successful operation in the field, production of the X1100™ continues. Allison has a long history of supporting the U.S. Military and its global partners. This relationship is built on Allison’s commitment to deliver unrivaled reliability and durability for the defense end market.

Built for The Demands of Combat:

The cross-drive transmission is geared for heavy tracked combat vehicles up to 75 tons, and can accept either a diesel or turbine engine rated up to 1,500 hp (1,118 kW). It offers four forward ranges, two reverse ranges and a cross-drive design that integrates steering and braking into a single compact, rugged unit.

The 3040 MX™ delivers high reliability and powerful performance to meet the decades long, demanding lifecycle of tracked vehicles.

Next-Generation Electronic Controls:

The 3040 MX™ is equipped with advanced electronic system controls to enable performance optimization. The transmission will accommodate future controls platform evolutions, enabling advancements in system performance over the lifecycle of the vehicle.

Built on Decades of Experience in The Field:

The 3040 MX™ was developed based on Allison’s proven X300 propulsion system, which has been integral to the European CV90 and Warrior IFV drivetrain solutions for more than 30 years.
