About this transmission
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).
