摘要： A method for controlling a transmission in a motor vehicle includes determining a temperature of a fluid in the transmission, determining whether the torque converter lockup clutch is applied, and determining an engine torque of the motor vehicle. Then, the torque converter lockup clutch is applied and the transmission is prohibited from up-shifting if the temperature of the fluid exceeds a threshold, the torque converter lockup clutch is not applied, and the engine torque exceeds a second threshold. Next, a tractive effort of the motor vehicle is determined and the torque converter lockup clutch is deactivated when the temperature of the fluid is less than a third threshold, the tractive effort is less than a fourth threshold, or the engine torque is less than the second threshold.

摘要： A method of controlling a driveline retarder of a powertrain including a transmission having a rotatable input shaft connected to an engine and an output shaft connected to the driveline retarder is provided. The method includes determining a set speed value and comparing the set speed value plus a customer modifiable constant value to a current rotational speed value of the output shaft. A driveline retarder cruise modulation torque request value is then calculated when the current rotational speed value of the output shaft is greater than or equal to the set speed value plus the customer modifiable constant value. The driveline retarder is controlled as a function of the driveline retarder cruise modulation torque request value. A powertrain configured to implement the aforementioned method is also disclosed.

摘要： A method for determining the condition of a transmission fluid filter and controlling an operator indicator to alert the operator that the fluid filter requires replacement is disclosed. The method includes monitoring a fluid pressure switch, determining an operating mode of the transmission, determining whether the operating mode of the transmission is changing, activating a timer if the operating mode is changing, recording the time, comparing the time to a predefined time threshold, determining whether the recorded time is greater than the predefined threshold, and activating the operator indicator to indicate that the fluid filter requires replacement if the recorded time is greater than the predefined threshold.

摘要： The present invention provides a method of selecting and implementing a shift schedule for a transmission in a vehicle that includes an output speed sensor and a controller. The method includes measuring output speed with the output speed sensor and comparing the measured output speed to an output speed threshold. The controller receives throttle percentage and compares the throttle percentage to a throttle threshold. The method also includes calculating output acceleration and transmission gear ratio with the controller. The shift schedule is selected based on the measured output speed, calculated output acceleration, calculated transmission gear ratio, and throttle percentage.
