The Continuously Variable Transmission, or CVT for short, has been around for some time. So, what is an e-CVT? Here are the ...

Toyota hybrids are known for using CVT transmissions. However, modern Toyota hybrids actually use something called an e-CVT.

The GM transmission was the first of its kind to use a hydraulically controlled planetary gearbox, allowing the gears to shift depending on the vehicle's travel speed.

Early automatic transmissions with names like Hydra-Matic, Dynaflow, ZF, and Hondamatic delivered simplistic driving, but heavy planetary gear systems and torque converters sacrificed fuel efficiency.

The transmission has more gears than Drive, Park, ... Typically, automatic transmissions are built with multiple planetary gear seats that form the different gear ratios the car will switch to.

A modern automatic transmission uses one or more sets of epicyclic or planetary gears (consisting of a sun, planets, and a ring gear) to achieve many different (typically between two and ten) gear ...

When it comes to transmissions, a geared continuously-variable transmission (CVT) is a bit of a holy grail. CVTs allow smooth on-the-fly adjustment of gear ratios to maintain a target speed or powe… ...

The transmission appears to be a very neat solution of the problems encountered in the usual planetary gear and friction-disk; types. as 30 miles on a gallon of gasoline under favorable conditions.
