ABSTRACT:
An automated transmission system includes a transmission brake which is used to apply a braking torque to the transmission, while the engine torque is negative and a transmission clutch is disengaged to effect a gear downshift, in order to avoid acceleration of the vehicle when the clutch is released and abrupt deceleration of the vehicle upon completion of the gear downshift.
