Introduction
The Rolls-Royce Silver Spirit Spur features a fully automatic transmission, consisting of a three-element hydraulic torque converter and a compound planetary gear train.
Key Components
The transmission includes multiple-disc clutches, roller clutches, sprag clutches, and friction bands to provide the necessary functions for gear changes.
A name plate on the transmission case displays the serial number, prefixed by letters indicating the model year.
Operation
The torque converter supplements the gears by multiplying engine torque when necessary.
The transmission has six selector positions: Park, Reverse, Neutral, Drive, Intermediate, and Low.
Each gear ratio can be multiplied by up to 2.2, depending on the slip speed of the converter pump and turbine.
