When oil pressure is applied to the K3 clutch (4), the clockwise turning effect of the P1 planetary annulus gear is conveyed and the P2 planetary annulus gear rotates clockwise.

When oil pressure is applied to the K1 clutch (2), the input shaft (1) and the sun gear shaft (12) are directly connected, the sun gear shaft (12) rotates clockwise.

As a result, the P2 planetary pinion gear revolves clockwise while rotating clockwise on its own axis, thus a clockwise turning effect is given to the P3 planetary annulus gear that is connected to the P2 planetary annulus (10).

This rotation and clockwise turning effect of the sun gear shaft (12) gives turning effect to the P3 planetary pinion gear to revolve clockwise while rotating clockwise on its own axis, and a clockwise turning effect then given to the P3 planetary annulus (9) and also to the output shaft (8).
