Abstract
A method of monitoring oil level in a transmission system of a machine is disclosed. The method includes monitoring an oil pressure and calculating an average value of the oil pressure over a first predetermined time duration. The method further includes calculating a variance of the oil pressure from the average value and recording a deviation if the variance is beyond a threshold variance. The method further includes detecting a low oil level condition if a count of deviations is above a threshold count within a second predetermined time duration.
