FUNCTION OF CLUTCH AND BRAKE:

CLUTCH AND BAND CHART:

POWER TRANSMISSION
"N" position
Since both the forward clutch and the direct clutch are released, torque from the input shaft drive is not transmitted to the output shaft.

"P position"





^ The same as for the "N" position, both the forward clutch and the direct clutch are released, so torque from the input shaft drive is not transmitted to the output shaft.
^ The parking pole linked with the selector lever meshes with the parking gear and fastens the output shaft mechanically.

2. Forward clutch operates. (Connect input shaft to main rear internal gear.)
3. Main rear internal gear rotates clockwise.

7. Main front internal gear is going to rotates counterclockwise.
8. One-way clutch No. 2 operates. (Lock counterclockwise rotation of main front internal gear.)
9. Main planetary carrier revolves clockwise due to reaction force of front small planetary pinion gear.
10. Counter drive gear rotates clockwise for main planetary carrier and one.
