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).
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 ...
The Saturn MP Transmission were a series of 5-speed manual and 4-speed automatic transmissions that were manufactured by Saturn Corporation exclusively for the S-Series.They were designed for transverse engine applications and was deployed in vehicles that output up to 122 ft·lbf of engine torque.
The average manual car driver takes between 500 ms and 1 s to perform vertical gear changes (i.e. 1st-2nd, 3rd-4th, 5th-6th) and 1 - 2 s to perform horizontal gear changes (i.e. 2nd-3rd, 4th-5th). Shift time is also dependent on gear throws (distance between gears), ease of movement, ergonomics of the gear stick , and gearbox condition.
The Multimode Manual Transmission has the following gears: R, N, E, M+, M−. R: R is the reverse gear. It is similar to R in both traditional manual and in fully automatic cars. N: N is the neutral gear. It is similar to N in both traditional manual and full automatic. E: E is the functional equivalent of D in a full automatic.
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.
Steering wheel-mounted transmission controls have made a comeback since the mid-1990s introduction of Porsche's Tiptronic system, although the controls for the selection of park, reverse, and neutral are almost always located elsewhere. They also invariably have the buttons or "paddles" for the functions that are on the steering wheel quite ...
The 2012-2016 DPS6 Powershift transmission was used in the 2012–2016 Ford Focus and 2011–2016 Ford Fiesta sedans. This transmission is the subject of a massive number of lawsuits alleging Ford lied in order to sell cars Ford knew had defective transmissions.
