Automatic Transmission History
The first automatic transmission was developed in 1932 by José Braz Araripe and Fernando Lehly Lemos, two engineers in Brazil, who later sold the plans to General Motors. General Motors introduced this transmission as the “Hydra-Matic” in their 1940 Oldsmobile. Automatic transmissions started becoming the norm in the US during the 1980s. During the adoption period, the automatic option was more expensive than a manual along with the added cost of fuel inefficiency, mostly due to slippage in the torque converter.
Manufacturers have been making improvements ever since, and modern car transmissions are more affordable, more reliable, and more fuel efficient. One improvements include adding more gears. According to the LA Times, less than 3% of cars sold in the US have manual transmissions.
