On the section for epicyclic CVT's ( /info/en/?search=Continuously_variable_transmission#Epicyclic ) the description refers to friction discs and then indicates the Prius E-CVT as an example. The E-CVT is epicyclic but uses differential input from multiple motors to produce ratio variability. There is not a friction component. — Preceding unsigned comment added by 67.5.110.26 ( talk) 17:57, 21 January 2021 (UTC)
Hydrostatic drives are used on quite large earthmoving equipment , notably large bulldozers. Here is an example of a 770HP drive https://www.mobilehydraulictips.com/fluid-power-drives-mega-dozer/ . The section should be reworded slightly to note that hydrostatic transmissions are very efficient at all power levels. Salbayeng ( talk) 22:34, 1 September 2020 (UTC)
In a hydrostatic system the fluid does not move, it is static = not move. All hydraulic power transmission systems rely on fluid movement and are therefore hydrodynamic. — Preceding unsigned comment added by 80.225.0.161 ( talk) 00:33, 8 March 2021 (UTC)

Should 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)
