A method for determining the condition of a transmission fluid filter and controlling an operator indicator to alert the operator that the fluid filter requires replacement is disclosed. The method includes monitoring a fluid pressure switch, determining an operating mode of the transmission, determining whether the operating mode of the transmission is changing, activating a timer if the operating mode is changing, recording the time, comparing the time to a predefined time threshold, determining whether the recorded time is greater than the predefined threshold, and activating the operator indicator to indicate that the fluid filter requires replacement if the recorded time is greater than the predefined threshold.
