Functions of Subaru automatic transmission shank clutches
Subaru automatic transmission shank clutches perform the following functions:
*Transmission of torque from the torque converter to the output shaft
* Coupling and disengaging the output shaft with the transmission
* Absorption of vibrations and shocks
Design of shank clutches of Subaru automatic transmission
Subaru automatic transmission shank clutches consist of the following components:
*Friction Pad: Made of a friction-based material such as carbon fiber composite that provides traction and friction.
* Friction base: The metal plate to which the friction lining is attached.
* Shank Splines: Serrated projections on the base of the clutch that connect to splines on the output shaft.
* Springs: Help to press the clutches against the metal discs.
Types of shank clutches for Subaru automatic transmissions
There are two types of Subaru automatic transmission shank clutches:
* One-sided clutches: They have a friction lining on one side only.
* Friction clutches on both sides: They have a friction lining on both sides.
Location of shank clutches of Subaru automatic transmission
The Subaru automatic transmission shank clutches are located at the very end of the output shaft, before connecting to the transmission.
