The advantage of this type of clutch is it gets rid of the opportunity of simultaneously applying the clutch release on two planetary gears.
Hydramatic Transmission: This is a completely automatic type of transmission. The Hydra-Matic drive combines the automatic 4-velocity forward and reverse-geared transmissions. Apart from, it makes use of a fluid flywheel such as the fluid coupling or the torque converter for the intent.
