Allison S5610M

The Allison S5610M is a rugged, fully automatic transmission designed for high-mobility tracked military vehicles and heavy off-road tactical platforms that demand powerful torque handling, reliable performance, and advanced shift control in the most extreme conditions. A member of Allison’s specialized “S” Series, the S5610M offers six forward speeds, one reverse, and features a lock-up torque converter for maximum power transfer and fuel efficiency. The “M” designation identifies this model’s configuration as optimized for military combat vehicle applications, featuring a compact, modular horizontal layout suitable for integration into armored hulls and confined engine compartments.

Built for durability, the S5610M provides smooth gear transitions, enhanced terrain-adaptive shifting, and electronic control logic that reduces driveline stress during aggressive maneuvers. Its internal pressure-lubrication system and integrated diagnostics ensure high reliability and long service life, even under continuous heavy load. The S5610M supports battlefield-ready vehicles such as armored recovery vehicles, combat engineering equipment, and tracked personnel carriers, and is fully compatible with modern C4ISR and electronic vehicle systems.
