    Automatic Transmission Oil Pressure Switch Replacement in Hamilton

    What is the automatic transmission fluid pressure switch?Transmission oil pressure switch replacement Hamilton NZ

    Inside your car’s automatic transmission flows a liquid called Automatic Transmission Fluid (ATF) (or transmission oil). Its job is to lubricate the various moving parts inside the transmission. This allows for smooth shifting of gears and prevents transmission parts from overheating and wearing quickly.

    The automatic transmission oil pressure switch is a vital component which monitors the amount of pressure built up in the transmission case as the oil passes through. It then sends this information to your car’s onboard transmission computer (ECU) which makes adjustments to your transmission’s behavior which allow for smooth and optimal gear changes.

    Many late-model cars will have several transmission pressure switches. The exact number, type and location of these switches may vary depending on your car’s make and model.

     

    When should an automatic transmission oil pressure switch be replaced?

    The transmission oil pressure switch works in a harsh environment and as a result, is subject to extreme conditions that can cause it to fail over time. The exact lifespan of a transmission oil pressure switch varies depending on several things. These include how your vehicle is driven, how often your transmission oil is changed and what condition the rest of your car’s transmission is in.

    You can extend the lifespan of your car’s transmission oil pressure switches by:

    • Replacing transmission oil with every 50,000 km or driving.
    • Replacing the automatic transmission filter the same time as changing the auto transmission fluid
    • Driving smoothly and minimising load on the engine and transmission to avoid over heating the automatic transmission.
