An automatic power transmission to which a lubricating device of the invention is applied is of a type which has an operation mode wherein when, under rotation of an input shaft, a pinion carrier is prevented from making a revolution, pinions carried by the pinion carrier are rotated. Future exceptions may be tracked by the system, provided to users before or at the time that they occur, and closed or otherwise managed by the system as they become relevant or are removed by further changes related to the supply plan. These parameters include the following: the vehicle is in park, the parking brake is engaged, the vehicle ignition is on, the lift power switch is on, and the lift door is open. At the start of the impact stroke the ram is uncoupled by a ball clutch.
