ABSTRACT:
A method and apparatus as presented for monitoring the condition of oil in a transmission to present a service indicia prior to the time that the oil life has been spent. A thermosensor and a tachometer are associated with the transmission to present respective output signals correlated with operating temperature and transmission revolutions. The revolutions of the transmission are weighted as a function of the deviation of the temperature from a temperature standard. The resulting effective revolutions are then applied to a down counter which is initially loaded to the number of allowable effective revolutions when the transmission oil is changed or the transmission serviced. When the down counter has counted out, a message is displayed indicating the need for service.
