During World War II, Allison applied its engineering knowledge and technology to ground transportation with the development of automatic cross drive transmissions. Production of the company’s first generation military tank cross drive, the CD 850, began
in 1949 and continued for 38 years. The CD 850 powered the M47, M48 and M60 tanks for the U.S. Army and many Allied nations, and is still in use around the world.
The CD 850 was followed by the XT1400/1410 cross drives for the M51 tank and M88 recovery vehicles; and the XTG 411 cross drive for the M109 and M110 howitzers and related vehicles. Production of the XT1400/1410 began in 1954 and continued for 34 years.
Production of the XT411 began in 1962 and continued for 39 years.
The venerable tracked M113 family of Armored Personnel Carriers has always been Allison equipped. The original version utilized the TX100 transmission while later versions used the X200 cross drive. The TX100 was produced for 33 years from 1964 through
1997; the X200 started production in 1986 and is still in production today, more than 27 years later.
Allison started production of the X1100 cross drive in 1979 for use in the U.S. Army’s M1 main battle tank. After more than 34 years, production of the X1100 continues today.
In 1981, as the popularity of the Allison military cross drives grew, Allison expanded its business with licensed global production programs. As a result, Allison military cross drives can be found in tracked vehicles produced in Allied nations around
