A method of controlling a start-stop vehicle transmission pump, includes: assessing how long an engine has been turned off; and when the engine has been turned off for longer than a predetermined threshold and the vehicle is on, priming the transmission pump.

A method for controlling a vehicle powertrain during launch includes controlling slip across a first clutch that transmits engine torque through the first clutch and the current gear while a transmission operates in a current gear other than a launch gear, disengaging the first clutch, engaging the launch gear, and controlling slip across a second clutch that transmits engine torque through the second clutch and the launch gear.

A method for controlling wheel-hop in a vehicle driveline includes detecting that a wheel-hop condition occurs upon determining an amplitude and frequency of speed oscillations of a component that transmits power to wheels of the driveline, engaging a transmission friction clutch that transmits torque in the driveline between an engine and the wheels, and modulating requested engine torque.
