Abstract: An auxiliary lubrication pump apparatus for use with towed vehicles having an automatic transmission. The apparatus includes a lubrication pump, a selector valve, a pressure sensing unit, a pump relay and a control unit and a display unit. The control unit includes a timer for sounding an alarm to alert the driver to activate the apparatus when the engine switch of the towing vehicle has been initiated. If pressure in the lubrication cycle drops below an acceptable level, or if electrical power to the apparatus fails, an audible alarm and visual alarm will be provided to the operator of the towing vehicle.
