Drive Range - Second Speed

In second speed, the intermediate clutch is applied to allow the intermediate sprag or roller clutch to hold the sun gear against counterclockwise rotation. Turbine torque through the forward clutch is now applied through the mainshaft to the rear internal gear in a clockwise direction.

Clockwise rotation of the rear internal gear turns the rear pinions clockwise against the stationary sun gear. This causes the output carrier and output shaft to turn clockwise in a reduction ratio of approximately 1.5 to 1. Further reduction is possible, at low speeds, due to torque multiplication provided by the converter.
