Hy-Drive
The Hy-Drive was a Chrysler Corporation semi-automatic transmission introduced in 1953 in US-market Plymouths. It was a hybrid manual transmission equipped with a torque converter, like an automatic. Although ''Hy-Drive'' cars had a clutch pedal like a traditional manual transmission, it was only used to put the car in gear. Once underway, the driver could upshift and downshift using the gear shift without using the clutch or even lifting off the accelerator. The industry was caught by surprise by the advent of the automatic transmission in the early-to-late-1940s. General Motors' '' Dynaflow'', introduced by Buick in 1948,Flory, p. 1017. was a smash hit with the public, very soon being fitted in over 80% of new Buicks. (GM's fully automatic Hydramatic Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by General Motors Corporation's Oldsmobile Division, the ''Hydramatic'' was the first mass-produced fully automatic transmission developed for passen ...

Semi-automatic Transmission
A semi-automatic transmission is a multiple-speed Transmission (mechanics), transmission where part of its operation is Automation, automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears. Semi-automatic transmissions were almost exclusively used in motorcycles and are based on conventional manual transmissions or sequential manual transmissions, but use an automatic clutch system. But some semi-automatic transmissions have also been based on standard hydraulic automatic transmissions with torque converters and Epicyclic gearing, planetary gearsets. Names for specific types of semi-automatic transmissions include ''clutchless manual'', ''auto-manual'', ''auto-clutch manual'', and ''paddle-shift'' transmissions. These systems facilitate gear shifts for the driver by operating the clutch system automatically, usually via switches that trigger an actuator or servomechanism, servo, ...

Presto-Matic
The M6 Presto-Matic was a Chrysler Corporation semi-automatic transmission produced from 1946 to 1953. It was a special manual transmission with a fluid coupling. Although it had just two forward gears, an electric overdrive unit was attached and useful in either gear for a total of four forward speeds. The driver would use the clutch pedal any time when selecting low, high, or reverse gear. Once underway, the accelerator could be eased and the car would engage the overdrive. With the Fluid Drive coupling, the car could be brought to a halt in gear without releasing the clutch and would creep like an automatic. The Presto-Matic name was only used on Chrysler-brand cars. DeSoto called the transmission the Tip-Toe Shift, while Dodge used Gyro-Matic, Fluid-Matic, Fluidtorque, or Gyro-Torque. Chrysler and DeSoto sold the unit from 1946 to 1953, while Dodge did not introduce it until 1948. Plymouth Plymouth ( ) is a port city status in the United Kingdom, city and unitary ...

PowerFlite
PowerFlite is a two-speed automatic transmission engineered and produced by the Chrysler Corporation and used in their passenger cars from 1954 to 1961. Production began in late 1953 and the simple and durable PowerFlite remained available on Plymouths and Dodges through the 1961 model year. Background Chrysler was the last of Detroit's Big Three automakers to introduce a fully automatic transmission, some 14 years after General Motors had introduced Oldsmobile's Hydramatic automatic transmission and nearly three years after Ford's Ford-O-Matic. Packard's Ultramatic debuted in 1949, and Studebaker's Automatic Drive was introduced in 1950. The PowerFlite was lighter and simple in its construction and operation, with fewer parts than competing transmissions. It was also durable, being used behind every Chrysler Corporation engine from the Plymouth Six to the Imperial's Hemi V8. Chrysler introduced a three-speed TorqueFlite automatic in 1956, but the two-speed PowerFlit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plymouth (automobile)
Plymouth was a brand of automobiles produced by Chrysler, Chrysler Corporation and its successor Mercedes-Benz Group, DaimlerChrysler. The brand was launched in 1928 to compete in what was then described as the "low-priced" market segment that was dominated by Chevrolet and Ford Motor Company, Ford. It became a high-volume seller for the automaker until the late 1990s. Plymouth cars were marketed primarily in the United States. The brand was withdrawn from the marketplace in 2001. The Plymouth models that were produced up until then were either discontinued or rebranded as Chrysler or Dodge. History Origins The Plymouth automobile was introduced at Madison Square Garden (1925), Madison Square Garden on July 7, 1928. It was Chrysler Corporation's first entry in the low-priced field previously dominated by Chevrolet and Ford. Plymouths were initially priced higher than the competition, but offered standard features such as internal expanding hydraulic brakes that Ford and Chevr ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canadian English, Canada, British English, the United Kingdom and American English, the United States), or stick shift (in the United States), is a multi-speed motor vehicle Transmission (mechanical device), transmission system where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace, and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission. Common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic ...

Torque Converter
A torque converter is a device, usually implemented as a type of fluid coupling, that transfers rotating power from a prime mover, like an internal combustion engine, to a rotating driven load. In a vehicle with an automatic transmission, the torque converter connects the prime mover to the automatic gear train, which then drives the load. It is thus usually located between the engine's flexplate and the transmission. The equivalent device in a manual transmission is the mechanical clutch. A torque converter serves to increase transmitted torque when the output rotational speed is low. In the fluid coupling embodiment, it uses a fluid, driven by the vanes of an input impeller, and directed through the vanes of a fixed stator, to drive an output turbine in such a manner that torque on the output is increased when the output shaft is rotating more slowly than the input shaft, thus providing the equivalent of an adaptive reduction gear. This is a feature beyond what a simple fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluid Drive
Fluid Drive is the trademarked name that Chrysler Corporation assigned to a transmission driveline combination which replaced the flywheel with a hydraulic coupling and performed the same function as a modern torque converter, only without torque multiplication. A conventional clutch, and three- or four-speed manual transmission was installed behind the fluid coupling. Fluid drive was used in many military vehicles produced for the US Armed Forces during the Second World War. It was offered for civilian use from 1939 through 1953 in Chryslers, 1940 through 1953 in DeSotos, and from 1941 through 1954 in Dodge models; a semi-automatic system was optional from Chrysler and DeSoto from 1941, and for Dodge from 1949. History The fluid coupling and torque converter was invented by the German engineer Foettinger in the early 1900s. For non-marine applications he licensed the development of the fluid coupling to the British engineer Harold Sinclair and his Fluidrive Engineering Co Ltd ...

Dynaflow
Dynaflow was the trademarked name for a type of automatic transmission developed and built by General Motors Buick Motor Division from late 1947 to mid-1963. The Dynaflow, which was introduced for the 1948 model year only as an option on Roadmaster models, was based on similar principles as those applied for the Torqmatic transmission used in the M18 Hellcat tank destroyer (built in Buick's Flint Assembly plant) and M26 Pershing tank during World War II, namely a multi-element torque converter and manually selected intermediate gears. It was also used in the 1951 Le Sabre concept car. History Original version The Dynaflow was an automatic transmission used in various forms in Buick cars by the General Motors Corporation from 1947 until 1963. The transmission initially used a five-element torque converter, with two impellers and two stators, as well as a planetary gearset that provided two forward speeds plus reverse. In normal driving, Dynaflow started in high gear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
