Components Activated In Selected Gears

Components activated in selected gears





Clutches:
- C1- Engages the input shaft with the rear planetary train (P1) ring gear.
- C2 - Engages the input shaft with the sun gear shaft for the primary shaft planetary trains (P1, P2).
- C3 - Engages the planetary gear carrier with the sun gear for the secondary shaft planetary gear (P3).

Brakes:
- B1 - Locks the sun gear shaft for the primary shaft planetary trains (P1, P2) so that it cannot rotate in any direction.
- B2 - Locks, using F1, the sun gear shaft for the primary shaft planetary trains (P1, P2) so that it cannot rotate counter-clockwise.
- 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 train (P3) so that it cannot rotate in any direction.

Freewheel:
- F1 - Prevents the sun gear shaft for the primary shaft planetary trains (P1, P2) from rotating counter-clockwise when B2 is engaged.
- F2 - Prevents the front planetary train (P2) ring gear from rotating counter-clockwise.
- F3 - Prevents the sun gear for the secondary shaft planetary train (P3) from rotating clockwise.

Gear shift solenoids:
- S1 - Controls shifting in the transmission. Activated in 2nd and 3rd gears.
- S2 - Controls shifting in the transmission. Activated in back-up (reverse) gear, 1st and 2nd gears.
