A transmission having a double rotation torque converter and including a central assembly in which is mounted both a first brake for securing the torque converter guide ring against rotation and a second brake which cooperates with a planetary gear to cause rotation of the guide ring oppositely from the turbine ring of the torque converter. The two brakes and at least part of the planetary gear are mounted in the central assembly. The guide shaft extending axially from the guide ring is radially journalled in the central assembly. The transmission also includes a fluid communication system which, in cooperation with a pump, controls the mode of operation of the torque converter. The pump and most of the fluid system passageways may also be located within the central assembly. The torque converter may include a releasable torque transmitting member and the transmission may include further gearing stages downstream from the torque converter and the central assembly. |
