A close-ratio transmission is one which is described relative to another transmission for the same vehicle model. The relativity applies only for the transmissions offered for a single make and model; that is, there is no specific threshold value or accepted industry standard that determines whether the steps between gears constitute a normal or close-ratio transmission.
Three-speed sliding-gear non-synchronous transmission Non-synchronous "crash" gearbox; commonly used today in semi-trucks and tractors, and formerly used in automobiles pre-1950s. 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 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]
[10] As the input torque of the driveshaft tries to turn the differential center, internal pressure rings (adjoining the clutch stack) are forced sideways by the pinion cross shaft trying to climb the ramp, which compresses the clutch stack. The more the clutch stack is compressed, the more coupled the wheels are.
The service manual explains that Autostick signaling is multiplexed on a single wire. The transmission control module outputs a 5v signal to the handle and monitors it for voltage drop The voltage ranges 0.3-1.6,1.6-2.8, 2.8-3.8, and 3.8-4.8 representing down, up, overdrive lockout, and all open respectively.
A dual-clutch transmission (DCT) (sometimes referred to as a twin-clutch transmission) is a type of multi-speed vehicle transmission system, that uses two separate clutches for odd and even gear sets. [1] The design is often similar to two separate manual transmissions with their respective clutches contained within one housing, and working as ...
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
