Transmission fluid serves the same purpose as engine oil – it lubricates moving parts and protects against friction damage. This fluid also serves another purpose. As you accelerate, the transmission fluid pump builds hydraulic pressure within the transmission. A transmission pressure oil switch reads the amount of pressure and then signals the computer. The computer takes that information and determines if the clutch should be engaged to shift. Your transmission will have several different transmission fluid pressure switches, but the exact number will depend on the year, make and model, as well as the type of transmission installed.
Pressure switches are subject to an enormous amount of wear and tear over time, particularly if you spend a lot of time in city driving situations where you don’t maintain a consistent speed for long periods. You may experience problems such as harsh shifts, a Check Engine light, or your transmission may be stuck in limp mode where you can’t accelerate out of second gear.
Most vehicles will never have a transmission pressure switch replaced in their lifetime. Regular transmission fluid changes can help prevent pressure switch failure most of the time. If you experience symptoms you believe may be a transmission oil pressure switch problem, have one of our expert mechanics diagnose it.
With faulty transmission fluid pressure switches, your transmission will not shift correctly. The Check Engine light will illuminate, and you may not be able to shift into higher gears.
