The X200-4A cross-drive transmission is designed for light-tracked combat vehicles weighing up to 16 tons. The X200-4A provides vehicle propulsion, integrated differential steering and integrated brakes, ensuring unmatched control and performance. This cross-drive transmission has been used in the M113A3 armored personnel carrier since 1986 and the return to production highlights the ongoing sustainment of this critical family of defense vehicles. To meet this initial contract, valued at approximately $35 million, Allison Transmission began deliveries of the X200-4A cross-drive transmission in June 2020 and will continue through March 2022.

“Allison is committed to providing the most reliable products to our customers, reducing mechanical down time and allowing crews to have more time to spend on training and mission readiness,” said Dana Pittard, Vice President for Defense Programs at Allison Transmission.

The M113A3 remains the Army’s single largest armored vehicle fleet with nearly 5,000 vehicles, and encompasses 30 percent of all tracked vehicles in an armored brigade. These vehicles provide medical, combat engineering, command and control, and indirect fire capabilities.

COVID-19 has had a devastating impact on the government, communities, families and businesses around the world. Allison Transmission is grateful for the dedication and resilience of the vehicle OEMs and our suppliers.

“The well-being of Allison employees remained at the forefront of all decisions and we worked closely with federal and local agencies to implement enhanced sanitation protocols​​​​​​ and policies to maintain the health and safety of our workforce,” said Casey McClain, Production Manager at Allison Transmission. Allison will complete all work at the Global Headquarters and manufacturing center in Indianapolis.

Since 1946, Allison has partnered with the Department of Defense to develop propulsion solutions that deliver in the toughest conditions. For fleets that are developing new wheeled or tracked vehicles, Allison can tailor a transmission specifically for that application. Allison engineers and manufactures reliable and fully customizable propulsion solutions, so customers experience reduced downtime and increased ability to accomplish objectives.
