Hydramatic
Hydramatic (also known as Hydra-Matic) is an automatic transmission developed by both General Motors' Cadillac and Oldsmobile divisions. Introduced in 1939 for the 1940 model year vehicles, the ''Hydramatic'' was the first mass-produced fully-automatic transmission developed for passenger automobile use. History During the 1930s, automakers sought to reduce or eliminate the need to shift gears. At the time, synchronized gear shifting was still a novelty (and confined to higher gears in most cases), and shifting a manual gearbox required more effort than most drivers cared to exert. The exception here was Cadillac's break-through synchromesh fully synchronized manual transmission, designed by Cadillac engineer Earl A. Thompson and introduced in the fall of 1928. Cadillac, under Thompson, began working on a 'shiftless' transmission in 1932, and a new department within Cadillac Engineering was created, headed by Thompson and including engineers Ernest Seaholm, Ed Cole, Owen Nack ...

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, received some severe early testing in the M18 Hellcat tank destroyer, which were built in Buick's Flint Assembly plant during World War II. 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 turbines and two stators, as well as a planetary gearset that provided two forward speeds plus reverse. In normal driving, Dynaflow started in high gear (direct drive), relying on the converter's 3.1:1 torque multiplication, Ref. 1963 Buick Service Manual to accelerate the vehicle. Low gear, obtained via th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile Series 70
The Oldsmobile Series 70 is a full-size midrange automobile produced by Oldsmobile between the 1939 and 1950 model years. Oldsmobiles of this time period were in an unusual "middle" position in GM's hierarchy of automobile brands. Chevrolet and Pontiac were the budget priced models, while Buick and Cadillac were the luxury brands. GM would share their "A" body platforms between Chevrolet, Pontiac, and "B" body on Oldsmobile and Buick, while leaving Cadillac on the senior "C" platform. Oldsmobiles were then branded as "luxury level" Chevrolet's and Pontiac's, while Oldsmobiles using the "B" platform were "budget priced" Buicks and Cadillacs. Competitors from Ford's Mercury (automobile), Mercury and Chrysler's DeSoto (automobile), DeSoto brands would give customers a choice to have Oldsmobile levels of luxury, while not paying as much for a comparable Oldsmobile. GM in later years would discontinue the Series 70 and the budget Oldsmobile Series 60, and introduce the Oldsmobile 88 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile Series 60
The Series 60 "Special" is a full-size car made by Oldsmobile from the 1939 through the 1948 model years. It was their entry-level model using the GM "A" body platform, giving Oldsmobile an entry level product with more standard features that would be optional on Chevrolet and Pontiac vehicles using the same platform. Initially, the engine size used was the company's flat head 6 cylinder, while senior models would use the flat head 8 cylinder. For marketing purposes, the Oldsmobile Series 60, or the Oldsmobile 66, took advantage of the national highway U.S. Route 66 established in 1926.It was with this generation that all GM vehicles experienced increased width dimensions to accommodate three passengers on the front bench seat and an additional three passengers on rear bench seat installed vehicles. This was accomplished with the deletion of running board thereby adding additional room inside the passenger compartment and upgrading the floor mounted gearshift to a steering column in ...

Introduced as a General Motors companion make program, companion make for GM's more expensive line of Oakland Motor Car Company, Oakland automobiles, Pontiac overtook Oakland in popularity and supplanted its parent brand entirely by 1933. Sold in the United States, Canada, and Mexico by GM, in the hierarchy of GM's five divisions, it was slotted above Chevrolet, but below Oldsmobile, Buick, and Cadillac. Starting with the 1959 models, marketing was focused on selling the lifestyle that the car's ownership promised rather than the car itself. By emphasizing its "Wide Track" design, it billed itself as the "performance" division of General Motors, which "built excitement." Facing financial problems and restructuring efforts, GM announced in 2008 financial crash, 2008 that it would follow the same path with Pontiac as it had ...

Automatic Transmission
An automatic transmission (sometimes abbreviated to auto or AT) is a multi-speed transmission used in internal combustion engine-based motor vehicles that does not require any input from the driver to change forward gears under normal driving conditions. It typically includes a transmission, axle, and differential in one integrated assembly, thus technically becoming a transaxle. The most common type of automatic transmission is the hydraulic automatic, which uses a planetary gearset, hydraulic controls, and a torque converter. Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT). An electronic automatic transmission (EAT) may also be called an electronically controlled transmission (ECT), or electronic automatic transaxle (EATX). A hydraulic automatic transmission may also colloquially called a " slushbox" or simply a "torque converter", although the latter term c ...

M5 Stuart
The M3 Stuart/Light Tank M3, was an American light tank of World War II. An improved version of the tank entered service as the M5 in 1942 to be supplied to British and other Commonwealth forces under lend-lease prior to the entry of the U.S. into the war. Afterwards, it was used by U.S. and Allied forces until the end of the war. The British service name "Stuart" came from the American Civil War Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 Light Tank. Unofficially, were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "Light Tank M3" and "Light Tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed tanks in World War II to engage the enemy in tank versus tank combat when used in the Philippines in December 1 ...

Cadillac V8 Engine
The term Cadillac V8 may refer to any of a number of V8 engines produced by the Cadillac Division of General Motors since it pioneered the first such mass-produced engine in 1914. Most commonly, such a reference is to one of the manufacturer's most successful, best known, or longest-lived 90° V8 engine series. These include the pioneering overhead valve cu in introduced in 1949, made in three displacements up to ; a introduced in 1963 that grew to ; and a introduced in 1968 and enlarged to . Also notable was the Northstar, which debuted in 1992 as a 4.6 litre, and was also produced in 4.4 L and 4.2 L versions. When the Northstar engine series ended production in 2010 it became the last General Motors division to retain its own proprietary V8 design. This changed when Cadillac created the twin-turbo 'Blackwing' engine in 2019. L-head The Type 51 was the first Cadillac V8. Introduced in 1914, it was the standard engine for 1915 Cadillac models. It was a 90° design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oldsmobile
Oldsmobile or formally the Oldsmobile Division of General Motors was a brand of American automobiles, produced for most of its existence by General Motors. Originally established as "Olds Motor Vehicle Company" by Ransom E. Olds in 1897, it produced over 35 million vehicles, including at least 14 million built at its Lansing, Michigan factory alone. During its time as a division of General Motors, Oldsmobile slotted into the middle of GM's five (passenger car) divisions (above Chevrolet and Pontiac, but below Buick and Cadillac), and was noted for several groundbreaking technologies and designs. Oldsmobile's sales peaked at over one million annually from 1983 to 1986, but by the 1990s the division faced growing competition from premium import brands, and sales steadily declined. When it shut down in 2004, Oldsmobile was the oldest surviving American automobile marque, and one of the oldest in the world, after Mercedes-Benz, Peugeot, Renault, Fiat, Opel, Autocar and Tatra (i ...

M24 Chaffee
The M24 Chaffee (officially Light Tank, M24) was an American light tank used during the later part of World War II; it was also used in post–World War II conflicts including the Korean War, and by the French in the War in Algeria and the First Indochina War. In British service it was given the service name Chaffee after the United States Army General Adna R. Chaffee Jr., who helped develop the use of tanks in the United States armed forces. Although the M41 Walker Bulldog was developed as a replacement, M24s were not mostly removed from U.S. and NATO armies until the 1960s and remained in service with some Third World countries. Development and production history British combat experience in the North African campaign identified several shortcomings of the M3 Stuart light tank, especially the performance of its 37 mm cannon. A 75 mm gun was experimentally fitted to a Howitzer Motor Carriage M8 – an M3 tank with a larger turret – and trials indicated that a 7 ...

Buick
Buick () is a division of the American automobile manufacturer General Motors (GM). Started by automotive pioneer David Dunbar Buick in 1899, it was among the first American marques of automobiles, and was the company that established General Motors in 1908. Before the establishment of General Motors, GM founder William C. Durant had served as Buick's general manager and major investor. In the North American market, Buick is a premium automobile brand, selling luxury vehicles positioned above GM's mainstream brands, while priced below the flagship luxury Cadillac division. Buick's current target demographic according to ''The Detroit News'' is "a successful executive with family." After securing its market position in the late 1930s, when junior companion brand Marquette and Cadillac junior brand LaSalle were discontinued, Buick was positioned as an upscale luxury car below the Cadillac.
