A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually ...
A non-synchronous transmission, also called a crash gearbox, is a form of manual transmission based on gears that do not use synchronizing mechanisms. They require the driver to manually synchronize the transmission's input speed (engine RPM) and output speed (driveshaft speed).
Float shifting can reduce clutch wear because it is used so much less (only for starting from a standstill). Conversely, improper engagement of a gear (when the engine and transmission speeds aren't matched) can cause wear on the synchros and lockouts, and damage the gears by physically grinding them together due to a difference in speed.
A dog-leg gearbox or dogleg gearbox is a manual transmission shift pattern distinguished by an up-over-up shift between first and second gear. [1] The layout derives its name from a dog's hind leg, with its sharp angles. Dog leg gearboxes were replaced in most mass production vehicles by transmissions with a standard gear layout.
This sudden external acceleration of the engine through the transmission also causes increased wear on the mechanics of the car. Therefore, a staple of advanced or professional manual-transmission driving is the "rev match", or "throttle-blip", in which the driver quickly brings the engine up to speed with the wheels by use of the throttle.
There have been three different output shafts for pickup trucks. Early four-wheel drive was a short 10 spline. Later, a 35-spline version was for 2 wheel drive, whereas 4WD units had a 32-spline output shaft. [1] The SM465 was the only manual transmission available for 1988-1991 R/V-series trucks and SUVs.

Preselector gearboxes were most common prior to the widespread adoption of the automatic transmission, so they were considered in comparison to the "crash gearbox" type of manual transmission. Preselector gearboxes were often marketed as "self-changing" gearboxes, [ 1 ] however this is an inaccurate description as the driver is required to ...
The early articulated haulers were rugged, lacked suspension and had manual transmissions. This made them uncomfortable, noisy and demanding to drive and contributed to operator fatigue. The lack of suspension, other than that inherent in the large tires, also put stress on the drive-train and chassis, making them unsuitable for high-speed ...
