Abstract
A method for controlling a vehicle drivetrain includes de-energizing a clutch that connects a differential output to a wheel, rotating said component through a sump by pulsing the clutch when a speed of a differential component is less than a reference speed, and cyclically pulsing the clutch while a speed of said component exceeds the reference speed and a count of a timer, started when the clutch is de-energized, exceeds a reference count.
