![]() ![]() Allison designed, developed and manufactured the first-ever automatic transmissions for heavy-duty vehicles including delivery trucks, city buses, and locomotives, starting from 1948. After World War II, Allison Transmission turned its attention to civilian transportation. General Motors began developing automatic transmissions with a hydraulic torque converter in the 1930s under its Product Study Group, offering it as an option for Oldsmobile for the first time in 1940. Allison stopped producing the CD-850 in 1986, but a licensed version was produced in Spain for more than a decade afterward. The CD-850 combined range change, steering and braking. ![]() In February 1945, General Motors formed the Allison Transmission Engineering Section, dividing the subsidiary into Aircraft Operations and Transmission Operations in 1946. Early transmission development Īlongside the development and production of the V1710, engineers at GM began designing the CD-850 cross-drive steering transmission for tracked military vehicles in 1941 the design was completed in 1944 and Allison was awarded the contract to manufacture the prototypes. Due to demand during World War II, Allison would add a second factory (Plant 5) and 23,000 new employees by the end of the war, Allison had built 70,000 V1710 engines.

It was the last race Allison's team ever entered as he turned his company's attention to aviation engineering, renaming it to Allison Engineering Company the aviation-focused company developed steel-backed bronze sleeve bearings for the crankshaft and connecting rods, and high-speed reduction gearing to turn propellers and Roots-type blowers. After the war, Allison entered a car in the 1919 Indy 500 and won. When World War I began, Allison suspended racing, and the Allison Experimental Company began machining parts, tools, and masters for the Liberty airplane engine - the main power plant used in the US war effort. Allison built a shop near the track and changed the team's name to the Allison Experimental Company the shop later became Plant No. 1. In addition to funding several race teams, James Allison founded the Speedway Racing Team Company on Septem and quickly gained a reputation for his work on race cars and automotive technology in general. In 1911, Allison's new track held the first Indianapolis 500 mile race. Allison, along with three business partners, helped fund and build the Indianapolis Motor Speedway. History Racing team Īllison began in 1909 when James A.
