Borg-Warner R-11 overdrive - 3-speed manual transmission with electric overdrive Ford used them up until 1975 in trucks. Borg-Warner T-50 transmission — 5-speed longitudinal manual - used by GM in its RWD H-Body cars and a few other limited light duty applications from 1976 to 1978;
The first 6-speed manual transmission was introduced in the 1967 Alfa Romeo 33 Stradale. The first 7-speed manual transmission was introduced in the 2012 Porsche 911 (991). [9] In 2008, 75.2% of vehicles produced in Western Europe were equipped with manual transmission, versus 16.1% with automatic and 8.7% with other. [10]
2019–present JR913E (JATCO Model 9AT (Type JR913E) 9-speed automatic transmission) — 9-speed, Original design by Mercedes-Benz, Jatco variant modified and produced by Jatco under license for Nissan and Infiniti vehicles (in reference to the JR913E only) [2] [3] [4]
The transmission fluid will quickly overheat, not to mention the repeated impacts on the stator clutch (next topic). Also, overheating transmission fluid causes it to lose viscosity and damage the transmission. Such abuse can in rare cases cause the torque converter to leak and eventually stop functioning due to lack of fluid.
Automated manual transmissions can be semi-automatic or fully-automatic in operation. Several different systems to automate the clutch and/or shifting have been used over the years, but they will generally use one of the following methods of actuation for the clutch and/or shifting: hydraulic or electro-hydraulic actuation, [12] electro-mechanical, [13] pneumatic, [6] [14] [15] electromagnetic ...
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 designation of wide versus close ratio affected the lowest gear ratio; [7] for example, the four-speed Muncie transmissions offered in General Motors performance vehicles included the M20 "wide ratio" transmission, which had a first gear ratio of 2.52 or 2.56:1, while the M21 and M22 "close ratio" transmissions had a first gear ratio of 2.20:1.
