Struggling Transmission? Check Your Oil Pressure Switch

If your car is giving you trouble when you try to shift gears, it is often in your best interest to get your transmission inspected. A properly functioning transmission allows your car to shift gears smoothly and keeps all its moving parts lubricated. Worried about your transmission? Our specialists at Prieto Automotive can help you figure out what’s wrong and how to fix it.

What is a Transmission Oil Pressure Switch?

Your vehicle’s transmission allows your car to shift gears smoothly. Transmission fluid moves from the master chamber to the slave chamber, building up pressure in the process. The transmission oil pressure switch then gauges how much pressure is built up within the transmission chamber and signals to the computer whether or not there is enough pressure to engage the clutch and shift gears.

What should I know about Transmission Oil Pressure Switches?

It is important to note that transmission oil pressure switches are not serviceable, but must be replaced when rendered defective. If the damage is severe, you may also have to replace the transmission control module. These switches are not typically inspected during mechanical services, but regular transmission fluid replacements can prevent damage and failure of your transmission.

When do I need to replace my Transmission Oil Pressure Switch?

According to Your Mechanic, “Most vehicles will never have a transmission pressure switch replaced in their lifetime.” You can take preventative care of your transmission pressure switch with regular transmission fluid changes.

Some signs it might be time to replace your transmission oil pressure switch is if your “Check Engine” light is on, the transmission shifts are harsh, won’t shift into higher gears or is in limp mode.

What happens during a Transmission Oil Pressure Switch Replacement?

When you bring your car in for a transmission inspection, the mechanic will first test the transmission oil pressure switch to see if it needs replacement. If it is defective, the existing switch will be removed and a new one will be installed. The new oil pressure switch is then tested for proper operation and the transmission itself is tested to ensure proper functioning of the oil pressure switch.

How much does a Transmission Oil Pressure Switch Replacement cost?

Replacing your transmission oil pressure switch can cost anywhere between $170 and $300, depending on the make and model of your vehicle, the cost of parts and the cost of labor. Mechanic labor prices can vary depending on the auto shop you choose, and the prices of parts will be higher on newer and luxury vehicles. Overall, this service is not extremely expensive but it is important.

How important is this service?

Left unrepaired, a faulty transmission oil pressure switch can cause your car to struggle with gear shifting, suffer damage to the transmission’s internal parts and eventually fail. This service is important in order to maintain the health of your transmission, and helps ensure that you are able to shift into higher gears without the “Check Engine” light worrying you.

In short, it’s very important to get your transmission serviced when you notice any symptoms of its degradation. You can schedule a check-up or servicing at Prieto Automotive via our website, or you can give us a call as a first step toward taking care of your car!
