    Abstract: A vehicle includes an engine, a transmission with a shift valve, an alternator, an auxiliary battery, a voltage sensor operable to measure an auxiliary voltage, and an electronic transmission range selection (ETRS) system. The ETRS system includes a controller, and also an electronic range selector device that transmits an electronic range request signal to the controller to request the shift of the transmission to a requested operating range. The controller executes a method to predict a loss of auxiliary power aboard the vehicle, and to control an action of the vehicle in response to the predicted loss of auxiliary power. The electronic range request signal is received from the range selector device and auxiliary voltage. The controller calculates a slope of a decrease in the measured auxiliary voltage. A control action is executed with the alternator is in the charging state and the calculated slope exceeds a calibrated slope threshold.

    Abstract: A system for locking a Park device in a transmission in an out-of-Park mode of operation includes a valve body that defines a bore, a solenoid connected to the valve body, a lock feature disposed in the valve body and interconnected with the solenoid, and a servo piston disposed within the bore of the valve body. The servo piston has a detent and the servo piston is interconnected to the Park device and is moveable between a first position and a second position. The detent is radially aligned with the lock feature when the servo piston is in the first position. Activation of the solenoid locks the lock feature into the detent of the servo piston to lock the Park device of the transmission in the no-Park mode.

    Abstract: A one-way clutch includes a clutch body and body bore. A clutch plate stack includes first, second, and third clutch plates, the first and third clutch plates fixed to the clutch body. The second clutch plate rotates axially on a longitudinal axis. The first clutch plate includes a first strut cavity and the second clutch plate includes a second strut cavity. A forward strut is rotatably connected to the second clutch plate and biased toward the first clutch plate. The forward strut when positioned in the first strut cavity defines a clutch engaged position preventing second clutch plate rotation in a first rotational direction, while allowing rotation in a second rotational direction. A reverse strut slidably disposed in a strut bore extends through the third clutch plate, is partially positioned in the second strut cavity and is displaced in the strut bore during rotation of the second clutch plate.
