Generally, a shift interlock solenoid replacement isn’t needed as the component is meant to last for the car’s lifetime. However, if the solenoid stops working, it might make it difficult for you to shift your car. Let’s find out what it is all about and how it can be replaced.
What is the Shift Interlock Solenoid?
Solenoids are essentially cylindrical coils that carry electric currents. These coils are made of metal wire. The shift interlock solenoid ensures that the car doesn’t shift from Park to Drive without applying the brake. It also enables the shifter to move between Reverse and Park, as well as move your vehicle into a neutral mode when it is stopped at an intersection with no traffic coming through on either side. If the solenoid doesn’t receive the signal from the brake pedal, the shifter will not move.
Why do you need Shift Interlock Solenoid Replacement?
A damaged Shift Interlock Solenoid doesn’t pose any danger as such. However, it does make it difficult to shift the car from Park to Drive and Neutral mode. This makes it difficult for the car to operate. So, it’s important to get a faulty shift interlock solenoid replaced.
When do you Need to Replace the Shift Interlock Solenoid?
If the Shifter isn’t moving out of the Park mode or the key doesn’t come out of the ignition, it might be a dysfunctional shift interlock solenoid. It’s worth mentioning that there can be other reasons for a car not coming out of Park mode. Also, if the brake lights aren’t working, the shift interlock might not work either.
