Components Activated In Selected Gears

Component Function


Clutches:

C1 Engages input shaft with rear planetary gear (P1) ring gear.

C2 Engages input shaft with sun gear shaft for primary shaft trains (P1, P2).

C3 Engages planetary gear carrier and sun gear for secondary shaft planetary gear (P3).

Brakes:

B1 Locks sun gear shaft for primary shaft trains (P1, P2) so that it cannot rotate in any direction.

B2 Locks with aid of F1, the sun gear shaft for primary shaft trains (P1, P2) 50 that it cannot rotate counterclockwise.

B3 Locks the front planetary train (P2) ring gear so that it cannot rotate in any direction.

B4 Locks the sun gear for the secondary shaft planetary gear (P3) so that it cannot rotate in any direction.

Freewheels:

F1 Prevents sun gear shaft for primary shaft trains (P1, P2) from rotating counterclockwise when B2 is engaged.

F2 Prevents front planetary gear (P2) ring gear from rotating counterclockwise.

F3 Prevents sun gear for secondary shaft planetary gear (P3) from rotating clockwise.

Solenoids:

S1 Controls shifting in the transmission. Activated on 2nd and 3rd gears.

S2 Controls shifting in the transmission. Activated on 1st and 2nd gears.
