Abnormal Conditions. T ransmissions used in high duty cycle applications should use fluid analysis certain that a proper fluid change interval is established. T ransmission fluid must changed whenever there is evidence dirt a high temperature condition. A high temperature condition is indicated the transmission fluid being discolored having a strong odor , fluid analysis. Local conditions, severity operation, duty cycle may require more less frequent fluid filter change intervals.
