Your car’s transmission has many transmission oil pressure switches. These switches go through a lot of wear and tear over time and might need replacement. Let’s find out what transmission oil pressure switch replacement is all about.

What is the Transmission Oil Pressure Switch?

The transmission oil pressure switch is an auto part that reads the required amount of hydraulic pressure. The device then signals the computer to determine whether the clutch needs to be engaged to shift. The number of transmission oil pressure switches will vary depending on the year, make and model of the car as well as the type of transmission installed.

Why does Transmission Oil Pressure Switch need Replacement?

With time, the transmission oil pressure switches will go through wear and tear and can eventually fail. The wear and tear are higher if you spend a lot of time driving on high-traffic roads where maintaining a consistent speed is difficult.

A faulty or broken transmission fluid pressure switch makes it difficult for the transmission to shift correctly. Shifting into higher gears can become incredibly difficult.  You might also have difficulty in accelerating out of second gear or the transmission can get stuck in a limp mode. And once the switch fails, it can only be replaced, not serviced.

It is important to remember that inspecting these pressure switches isn’t a part of your regular car maintenance. And if the damage is too severe, transmission control module replacement may also be required.

When do you need Transmission Oil Pressure Switch Replacement?

Some of the common symptoms of the need to replace the transmission fluid pressure switch are as follows:

  • Your car’s check engine light will be illuminated
  • Shifting becomes harsh
  • Your car’s transmission remains stuck in limp mode
  • Shifting to higher gears becomes impossible
  • Accelerating the car out of second gear isn’t possible

How is it Done?

If you face any of the above issues, have a certified mechanic inspect the transmission oil pressure switch. If they verify the need to replace the switch, it will be done in the following manner:

  • Remove the faulty transmission oil pressure switch and install a new one
  • Test the transmission oil pressure switch for operation

Final Words

Generally, your vehicle might not need a transmission oil pressure switch replacement in its lifetime, especially if you change the transmission oil regularly. However, if the pressure switch fails, you can get it replaced by one of Swezo’s top-rated and certified mechanics.
