A heavy duty version of Aluminium Powerglide was offered for passenger cars equipped with the 409 cubic inch V8 engine, and Chevrolet light trucks using a 1.76:1 reduction planetary gear set, instead of the usual 1.82:1. With a 3.31 axle, Car and Driver magazine noted a full-throttle up shift speed of 76 mph (122 km/h) to direct with the 409 ...
The ST300, used with V-8 engines had additional clutches in the clutch packs, so they could handle the extra power of the larger engines. One of the clutch drums and/or apply piston in the ST300 was often used to 'beef-up' a Powerglide for high performance/racing uses. Chevrolet 'beefed-up' the Powerglide by using a different planetary gear ratio.
The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
The basis of the Turboglide's unique abilities was its five-element torque converter.Most automatic transmissions have a three-element torque converter, consisting of an impeller (an engine-driven pump); a turbine that rotates with the flywheel; a transmission-driven turbine that receives the energy of the oil propelled by the impeller, and a stator that redirects the recirculating oil so that ...
It used a planetary gearset with a clutch pedal for starting from a standstill and switching between the "low" and "high" ranges. [43] [44] [45] The Automatic Safety Transmission was replaced by the fully-automatic Hydra-Matic for the 1940 model year. [46] [47]
The "MN4" 4T40E is able to handle vehicles up to 4000 lb (1814 kg) GVWR. The final drive ratio can vary depending on the car's curb weight and engine power output. 3.91, 3.63, 3.29, 3.05, 3.69, and 3.42 are all of the available ratios used in the 4T40 (and 4T45) transmission; Made possible by using combinations selected from 3 different sprocket combinations (32/38, 35/35, 33/37) and 2 ...
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.
Corvair Powerglide was an all-new design, but borrowed a couple small parts from Chevrolet Turboglide and its operating concept is very similar to conventional Chevy Powerglide. Aluminum Powerglide , introduced in the conventional Chevrolet models in 1962 (starting with Chevy II ) incorporated many features pioneered by Corvair Powerglide ...
