The popularity of manual transmissions in automobiles is dropping sharply, with only about two percent of all cars sold in 2018 being manual. This shouldn’t be surprising: for manufacturers, it’s a lot simpler to put out one kind of car instead of two.
Semi-trucks are a different story, and the percentage of manual transmission trucks on the road is much, much higher. The manual transmission doesn’t have to worry about purely automatic transmissions – it has to worry about an advancement that works like an automatic in the cab, but internally is a manual. The big thing in transmissions is the automated manual transmission, and if it hasn’t already come to a fleet near you, it won’t take long.
