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 ...
The first through fourth gears are accessed when a low range is selected. To access the fifth through eighth gears, the range selector is moved to high range, and the gear lever again shifted through the first through fourth gear positions. In high range, the first gear position becomes fifth, the second gear position becomes sixth, and so on.
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 ...
Before the introduction of transmission synchronizers in 1927, [2] double clutching was a technique required to prevent damage to an automobile's gearing during shifts. Due to the difficulty and most often unnecessary redundancy involved in the technique, coupled with the advent of synchronized gearing systems, it has largely fallen into disuse in light vehicles.
The second overdrive is with ring 2 braked which will cause sun 2 to spin faster than in the first overdrive gear. There is one reverse gear. Ring 1 and ring 3 are braked with the input only connected to sun 1. Sun 1 will drive ring 2 in the forward direction and with carrier 2 braked, sun 2 and sun 3 will spin in reverse.
