Gearbox Transmission

The Manual Transmission

The manual transmission, which is also known as a “standard transmission” or a “stick shift”, is a type of transmission that utilizes a driver-operated clutch to regulate torque transfer from the engine to the transmission. The clutch is typically engaged or disengaged by a foot pedal or hand lever. Because they are the simplest, mechanically speaking, of the three types of transmissions, they also often have the longest lives, because there is less to go wrong. They also often offer the best fuel economy and manual transmission vehicles are typically a bit cheaper. Some drivers even enjoy driving them more.

The Automatic Transmission

Controlling a vehicle at low speeds is typically easier with an automatic transmission rather than a manual, because of a side effect of the clutchless fluid-coupling design called “creep” that causes the car to want to move while in a driving gear, even at idle. Fun fact: the automatic transmission was invented by Alfred Horner Munro of Regina, Saskatchewan, in 1921.

The CVT – Continuously Variable Transmission

The continuously variable transmission (CVT), also known as a shiftless transmission, is a variant of the automatic transmission that can change seamlessly through a continuous range of effective gear ratios as opposed to a fixed number of gear ratios. The CVT's belt-driven design offers approximately 88% efficiency, which is lower than that of a manual transmission, but this can be offset by lower production cost and by enabling the engine to run at its most efficient speed for a range of output speeds.
