    Abstract: A vehicle includes an engine, a transmission, and a controller. The transmission includes a pressure control solenoid (PCS) valve device having a PCS and a regulating valve, a friction clutch, and a clutch piston in fluid communication with the regulating valve. The piston is operable to apply a clutch pressure to the friction clutch during a shift of the transmission. The controller is programmed to receive an acceleration value describing a lateral and/or longitudinal acceleration force of the vehicle, calculate the clutch pressure using the received acceleration value, and control an operation of the regulating valve via the PCS using the calculated clutch pressure. The acceleration value may be determined via one or more accelerometers or calculated. A method is also disclosed for compensating for acceleration in control of the regulating valve in a vehicle having a transmission that includes a friction clutch, PCS, and regulating valve.

    Abstract: A control system for a transmission of a vehicle includes a first angular rotation module, a second angular rotation module, and a lash module. The first angular rotation module determines a first angular rotation of a first shaft during a first predetermined period based on a first signal generated by a first shaft sensor. The second angular rotation module determines a second angular rotation of a second shaft during the first predetermined period based on a second signal generated by a second shaft sensor. The lash module selectively detects lash between gears of the transmission based on the first angular rotation and the second angular rotation.

    Abstract: A control system for a transmission of a vehicle includes a first angular rotation module, a second angular rotation module, and a slip module. The first angular rotation module determines a first angular rotation of a first component of the transmission during a predetermined period based on a first signal generated by a first sensor. The second angular rotation module determines a second angular rotation of a second component of the vehicle during the predetermined period based on a second signal generated by a second sensor. The slip module selectively indicates that a clutch of the transmission is slipping based on the first angular rotation and the second angular rotation.
