It has a single ring gear that is usually the output with the transmission, but it has two Solar gears and two sets of planets.
This easy guideline will stop working every little thing you need to know about gearboxes in the car. It will describe how guide and automatic transmissions function to leverage motor power and provide it to your wheels. So, let us get started.

The transmission was delicate to motor throttle placement and street speed, developing thoroughly automatic up- and down-shifting that diversified In accordance with functioning problems. Functions in the Hydra-Matic provided a wide unfold of ratios (permitting both very good acceleration in initially equipment and cruising at low engine velocity in best gear) as well as fluid coupling handling only a portion of the motor's torque in the highest two gears (rising gas economy in those gears, comparable to a lock-up torque converter).
