A method and system adjusts powertrain controls to avoid significant deviations from set speed during speed control operation. Low vacuum conditions of a reservoir vacuum resulting from high load conditions are detected and eliminated through the initiation of downshifts. Detection is based on the determination that speed control mode has been initialized, the throttle is extended, vehicle acceleration is low, and there has been a significant deviation from set speed. The downshift creates an increase in engine rpm and a reduction in throttle angle to increase the manifold vacuum and thereby recharge the reservoir vacuum and eliminate the low vacuum condition. The transmission can be returned to normal operation and the pre-adjustment gear upon elimination of the low vacuum condition or the occurrence of a driver override condition.

A method of controlling an automatic transmission of a motor vehicle operating in a automatic speed control speed mode is provided. The first step in the method is measuring the torque output of the engine. A torque load acting on the transmission in a first gear is then determined. A maximum torque capable of being produced by the engine is then predicted. A torque output of the transmission in a second gear is then determined based upon the predicted maximum torque capable of being produced by the engine. A transmission shift from the first gear to the second gear is then allowed if the determined torque output of the transmission in the second gear is greater than the torque load of the transmission in a first gear.

A method for selecting between first and second manual shift modes for an automatic transmission is provided. The method includes the steps of providing a gear shift lever with first and second manual positions, placing the gear shift lever in a first manual position, and subsequently placing the gear shift lever in a second position. The method further includes the steps of selecting the first manual shift mode if the gear shift lever remains in the second position for a predetermined time period, cycling between the second and first manual positions while the gear shift lever remains in the second position, and setting a current manual mode equal to a last one of the first and second manual mode prior to the gear shift lever being released.

An apparatus and method for providing manual shift modes for an automatic transmission for a motor vehicle is provided. A plurality of sensors are coupled to the automatic transmission and the motor vehicle and are adapted to sense a plurality of parameters thereof and produce a plurality of respective sensor signals. An input device, responsive to manipulation by a driver, is adapted to produce one of an upshift signal and a downshift signal and a mode setting signal in response thereto. A controller is coupled to the automatic transmission and the input device and is adapted to receive the mode setting signal and the sensor signals and select one of a first and second manual modes in response thereto and to receive one of the upshift and downshift signals and responsively shift the automatic transmission in response to the sensor signals and the selected one of the first and second manual modes.

A method and apparatus for providing first and second automatic shift modes for an automatic transmission. Shifting of the automatic transmission is controlled by a transmission controller. The driver selects a control mode by manipulating an input device. The controller controls the operation of the automatic transmission using a first set of operating characteristics and a second set of operating characteristics in response to receiving the first mode signal and the second mode signals, wherein the first and second sets of operating characteristics include engine management characteristics.
