In Second gear, the UD clutch (1) is applied to provide input torque. The UD hub is splined to the rear sun gear.
When the UD clutch is applied, the UD hub and rear sun gear are driven. The L/R clutch (2) is applied to hold
the front carrier/rear annulus assembly. By doing so, the rear planet gears are forced to rotate around the inside
of the stationary rear annulus. The rear carrier/front annulus assembly rotates as an output member with a
reduction gear ratio of 2.84:1.
Power from the main centerline transfers to the underdrive compounder gear set annulus by way of the transfer
gears and the underdrive shaft. The direct clutch (3) is applied to drive the underdrive compounder sun gear at
the same speed as the underdrive annulus. With two members driven, the underdrive compounder gear set
operates in direct, or 1:1.
The main centerline ratio of 2.84:1 is multiplied by the underdrive compounder centerline ratio of 1:1. As a
result, the ratio through the entire gear train to the final drive in Second gear is 2.84:1.
