    摘要: A control system for a hydraulic automatic transmission includes a fault detection module and a transmission diagnostic module. The fault detection module detects faults of components of the transmission, wherein the faults may indicate low hydraulic fluid pressure in the transmission or failure of one or more of the components. The transmission diagnostic module determines whether the faults are due to low hydraulic pressure based on the detected faults, a predetermined number of faults, and a plurality of conditions.

The system includes a transmission, a transfer case, and a transmission controller. The transmission has a plurality of gears for establishing a plurality of gear ratios. The transfer case is coupled to the transmission by an output shaft. The transmission controller is in communication with a plurality of control devices for controlling the operation of the transmission. The controller includes control logic for controlling the engagement and disengagement of the auxiliary equipment. The control logic has a first control logic for determining whether an operator has actuated a selector switch, a second control logic for actuating a torque transmitting device to engage or disengage the auxiliary equipment and avoid gear clash, a third logic for monitoring the engagement or disengagement of the auxiliary equipment, and a fourth control logic determining whether the auxiliary equipment has been engaged or disengaged.
