ABSTRACT:
A transmission control apparatus includes transmission lines disposed between a pair of transmission shafts and a hydraulic multiple disc transmission clutch disposed on one side of the transmission lines. Power from an engine is transmitted via one of the transmission lines to a traveling unit. Each of the transmission lines has a friction clutch. A first gear mechanism operated by a first actuator is disposed between one of the transmission shafts and the first transmission line. A second gear mechanism operated by a second actuator is disposed between one of the transmission shafts and the second transmission line. When the first transmission line is powered, a first system operates the second gear mechanism into a speed position; the first clutch to a non-transmitting state and the second clutch to a transmitting state, thereby providing a progressive shifting of the transmission clutch from a transmitting state to a semi-transmitting state.
