Re: Liberty 2,8CRD Aut. "Line Pressure"
Line pressure is the regulated pressure inside the tranny, which is used for the application of the clutches. If the tranny is shifting normally, its most probably the line pressure sensor itself. You could start cleaning the connector on the sensor and disconnect the battery for a reset and try again.
