Due to its two-speed with torque converter design, the Super Turbine 300 is often confused with Chevrolet's Powerglide — which was also a two-speed torque converter transmission, but the ST 300 had a different design from the Chevy unit, which had been around since 1950. The low band was the same as the 1955 up PG along with the same style ...
For the 1968 model year, Chevrolet introduced a semi-automatic version of Powerglide marketed under the name Torque-Drive. This unit was basically Powerglide without the vacuum modulator, requiring the driver to manually shift gears between Low and High. The quadrant indicator on Torque-Drive cars was, Park-R-N-Hi-1st. The driver would start ...
Dynaflow (Buick) 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.
Since 2014 season, Formula 1 cars currently use mandatory 8-speed paddle-shift gearboxes. The now-defunct CART Champ Car Series switched from a lever-shift sequential system to a 7-speed paddle-shift system for the 2007 season. This transmission was introduced with the new-for-2007 Panoz DP01 chassis.
In first gear, the input is locked to the first ring. The first carrier is locked to the output and second ring. The second carrier is locked so its ring motion causes the common sun to spin retrograde. The retrograde spin reduces the first carriers reaction to its ring motion thereby doubling the reduction of the first set and output. [3]
Locking the planetary geartrain provided a 1:1 direct drive. The differential driven rear pump permitted push-starting the Powerglide-equipped Corvair (the last American automatic to do so), at speeds over 18 mph (29 km/h) by creating adequate pressure to engage low band and turn over the engine via the torque converter.
Roto's disadvantage was the 2-3 range or 1-2 gear change because it is not only a huge ratio jump from 2-3 range or 1-2 shift from 2.93 to 1.56, but also there is no fluid slippage in the coupling because the coupling drains (four-tenths of a second) to engage or apply the front clutch and so the trans goes to full mechanical connection.
