Of course it is :) It's nice-nicer-nicest. And remember-there's no such thing as a real word.. If a word is used and people understand it, then it is just as real â¦ as any word in any dictionary, or any word approved by your English teacher!
In British English, the term drive shaft is restricted to a transverse shaft that transmits power to the wheels, especially the front wheels. A drive shaft connecting the gearbox to a rear differential is called a propeller shaft, or prop-shaft. A prop-shaft assembly consists of a propeller shaft, a slip joint and one or more universal joints.
In this transmission, when overdrive is engaged, a shaft that is attached to the housing of the torque converter (which is bolted to the flywheel of the engine) is connected by clutch to the planet carrier. The small sun gear freewheels, and the larger sun gear is held by the overdrive band.
