The 1st one-way clutch and the front brake regulate counterclockwise rotation of the under drive carrier.
NOTE: The front brake operates at the fixed speed or less.
The rear carrier and the mid internal gear are fixed by the reverse brake.
The mid sun gear rotates at the same speed as the rear sun gear by operation of the 2nd one-way clutch and the high and low reverse clutch.

NOTE: The high and low reverse clutch operates at the fixed speed or less.

Each planetary gear enters the state described below.
