Transmission general data
The
9-speed automatic transmission Hydra-Matic 9T50 for front-wheel drive vehicles was
designed by GM and was officially showcased in December 2016. This transmission
was intended to replace its 6-speed predecessor. According to GM engineers, the
9T50 transmission allows striking a balance between high dynamic parameters and
fuel economy. The size of this transmission is the same as the size of its
6-speed predecessor, but the Hydra-Matic 9T50 also supports start/stop
technology and has a new torque converter.

One
of the peculiarities of this transmission is a selective clutch, which may
disconnect the transmission from the engine and operate in the rundown mode.
The first car to operate with this transmission was Chevrolet Malibu. The first
gear of the 9T50 transmission is very short (gear ratio is 4.69), so the car
can move very smoothly from a standstill. The 9-th gear is designed for
economical and more relaxed driving (gear ratio is 0,62).
