Buick Twin and Triple Turbine Dynaflow
editShould there be a section on Buick Twin Turbine (53-63) and Triple Turbine (57-59) transmissions ? These transmissions are often referred to as 2 (twin turbine) or 3 (triple turbine) speed automatics, but they were not actually shifting when in Drive, instead having a continuously varied overall reduction ratio resulting from the relative speeds of 2 or 3 turbines in the torque converter, each driving different inputs of an epicyclic geartrain.
In particular, the Triple Turbine variant and its close cousin at Chevrolet, the Turboglide, didn't even have a Low gear setting, and could offer reduction from 4.5-4.7:1 up to 1:1 seamlessly without shifting. They were hydraulic CVTs, but not of the "hydrostatic" nature. Clarrieu (talk) 10:04, 21 December 2023 (UTC)
Geared CVTs
editNew research has made a promising leap in the CVT field: A team called Ratio Zero has made a prototype CVT that uses gears. This promises a 20+% leap in efficiancy. But this is not the first time a geared CVT has been attempted. I believe there needs to be a new section specifically on geared type CVTs. Maldomeal (talk) 15:40, 21 February 2025 (UTC)
