The initial automatic transmission to work with a torque converter (as opposed to a fluid coupling) was the Buick Dynaflow, which was launched to the 1948 design year. In normal driving, the Dynaflow made use of only the leading gear, depending on the torque multiplication with the torque convertor

Consequently, it maximizes the torque multiplication Using the stator, which modifies the fluid flow depending on the impeller and also the turbine’s relative rotational speeds. The stator itself isn't going to rotate. Nonetheless, makers form their vanes making sure that if the impell

The central reactor converts this turning energy by redirecting the move of fluid again for the impeller to give increased torque at low speeds. The gear selector is definitely the input by which the driving force selects the working manner of the automatic transmission.[32] Traditionally the
