Abstract: A vehicle includes an engine and a transmission having an input shaft operably coupled to the engine, an output shaft operably coupled to wheels of the vehicle, a primary pump, and a secondary pump. The primary and secondary pumps are each configured to supply pressurized fluid to a valve body of the transmission. A controller is programmed to, in response to a loss of pressure of the primary pump and a speed of the output shaft exceeding a first threshold, shift the transmission to a neutral state, energize the secondary pump once the transmission is in the neutral state, and command the engine to idle speed.

Abstract: A system and method for controlling a vehicle include a manual transmission operated by a controller in communication with shift actuators and programmed to, in response to each controller reset less than a threshold number of resets, control each shift actuator that was not moving at the time of the reset based on respective shift actuator positions stored prior to the reset, and to control the shift actuators to limit available gear ratios in response to the reset exceeding the threshold number of resets.

Abstract: Methods and systems for operating a vehicle powertrain that includes an engine and a transmission including a power take off output are presented. In one non-limiting example, engine speed may be adjusted responsive to a level of a signal input to a controller. The controller may select an operating mode responsive to the level of the signal input to the controller.

Abstract: An exemplary pump condition response method includes, in response to a pump condition, operating an engine to discontinue or prevent a first stop-start cycle during a drive cycle. The method permitting a second stop-start cycle during the drive cycle.

Abstract: A method for controlling a transmission gear change to a desired gear includes disengaging an offgoing transmission control element, changing engine speed to a synchronous speed of the desired gear, decreasing engine output torque, and engaging an oncoming transmission control element.
