How much does it cost to replace a shift interlock solenoid?

$195 to $215 is the average total repair cost for a shift interlock solenoid replacement. The exact price will depend on your vehicle.
How long does it take to replace a shift interlock solenoid? In most cases, it takes about 15 minutes for a certified mechanic to complete this job. First, the mechanic will assess your vehicle in an initial inspection to confirm the issue, and then they’ll replace the part.

How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my shift interlock solenoid replacement and how much do those parts cost?

You can check your owner’s manual or ask your mechanic for precise parts, but here’s a general rundown:
  1. Shift interlock solenoid: It is part of the shifter assembly in the center console or steering column. It turns electrical energy into mechanical energy, allowing a plunger to be moved between gears—and it only operates after the brake pedal has been depressed. The average cost for a shift interlock solenoid can range from $50 to $150, depending on the brand and quality of the part.
  2. Shifter assembly: In some cases, you might need to partially disassemble or remove the gear shifter assembly to access the shift interlock solenoid. Replacing the entire shifter assembly can be very expensive, ranging from $200 to $500 or more.
  3. Collector: This is the electrical connector that connects the shift interlock solenoid to the vehicle's wiring harness. The replacement cost for the electrical connector (collector) can be relatively low, usually ranging from $10 to $30.
  4. Brake light switch: The brake light switch is connected to the brake pedal and plays a crucial role in the shift interlock system. It sends a signal to the shift interlock solenoid when the brake pedal is pressed, allowing the gear shifter to move out of "Park." The average cost for a
    brake light switch
    is generally around $20 to $50.
  5. Replacement gasket or seal: Depending on the specific vehicle model, you may need to replace the gasket or seal that keeps the shift interlock solenoid in place to prevent leaks. On average, the cost ranges from $5 to $30 depending on the model.
  6. Release rod: This is a mechanical component that allows you to manually release the shift lock in case the shift interlock system fails or if there's an electrical issue preventing the solenoid from functioning correctly. The replacement cost for a release rod is usually around $20 to $50.
  7. Springs: Springs may be present, providing tension and assisting with the proper functioning of components. The cost of springs, if needed, can be relatively low, typically ranging from $5 to $20 per spring.
  8. Solenoid mounting: The shift interlock solenoid may be mounted to a bracket or housing using screws or bolts. The cost for mounting hardware (screws, bolts, etc.) is generally minimal, usually a few dollars.
We recommend purchasing parts at local auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, as well as online retailers like Amazon and RockAuto. We also recommend trusted brands such as Dorman, ACDelco, and Standard Motor Products for shift interlock solenoid components, ensuring proper gear shifting and safety for your vehicle. However, like price, recommended brands may also vary depending on your vehicle’s specific year, make, and model.
OEM parts are directly from the original manufacturer, ensuring higher compatibility and reliability but can be more expensive.
Aftermarket parts
are more affordable, but quality may vary, affecting performance and longevity. Weigh cost, warranty, and reviews to make an informed decision.
You can buy parts for your shift interlock solenoid replacement from auto parts stores like AutoZone, Advance Auto Parts, O'Reilly Auto Parts, online retailers like Amazon and RockAuto, authorized dealerships, and automotive salvage yards. Ensure you choose reputable sellers to guarantee quality and compatibility—and double-check the part number so you get the correct solenoid pack.

How will a mechanic replace my shift interlock solenoid?

Replacing a transmission shift solenoid typically involves removing the center console or accessing the steering column. First, the mechanic should diagnose the issue.
Here are the steps:
  • Disconnect the vehicle's battery to avoid electrical hazards.
  • Remove any components or covers that obstruct access to the shift interlock solenoid.
  • Disconnect the electrical connector from the solenoid.
  • Remove the old shift interlock solenoid from its mounting location. This may involve removing screws or bolts.
  • Install the new shift interlock solenoid in the proper orientation.
  • Reconnect the electrical connector.
  • Reassemble any components or covers that were removed.
Once you’re done, test the new shift interlock solenoid by pressing the brake pedal and attempting to move the gear shifter out of "Park."
If everything functions correctly, the replacement is successful! If not, retrace your steps and double-check the connections.

What happens if I don’t replace my shift interlock solenoid?

If you don’t replace your shift interlock solenoid when it’s failing, consequences may include:
  • Vehicle may become immobilized in "Park"
  • Inability to shift gears, leading to inconvenience and potential towing costs
  • Compromised safety feature, allowing accidental gear shifts without engaging the brake pedal
  • Increased risk of accidents or injuries due to potential unintended vehicle movements
  • Potential damage to other components in the shift interlock system
  • Reduced overall safety and control while driving

What is a shift interlock solenoid?

A shift interlock solenoid keeps the pistons and valves in your car’s engine running smoothly. It’s used in automatic transmission vehicles like the Ford F-150, not manual transmission vehicles.
In order to keep the correct fuel/air mixture running into your engine and exhaust gas leaving, the shift interlock solenoid has to coordinate the motion of
the camshaft and crankshaft
, which control the engine’s pistons and valves. 
When it’s correctly working, this system protects the transmission parking pawl, which is a pin located inside the transmission that locks the output shaft when the gear lever is set to park. The parking pawl prevents the drive wheels from moving, acting as an emergency backup if the handbrake fails.
This is a critical part—a failing shift interlock solenoid can lead to
engine misfires
and eventually to catastrophic engine failure. 
The solenoid works with the transmission control module (TCM) to ensure the safe and efficient operation of the automatic transmission system, with the transmission control unit coordinating the release of the shift interlock solenoid when the conditions for shifting gears are met. The valve body receives signals from the TCM based on speed sensor inputs to determine when and how to engage specific gears.

When should I replace the shift interlock solenoid on my car?

The shift interlock solenoid does not require servicing. It is meant to last the lifetime of your car. 
However, here are key signs of a solenoid problem:
  • Your shifter will not come out of Park
  • Your vehicle gets stuck in gear
  • Your key will not come out of the ignition
Be alert to any issues specifically with your downshift, as this could indicate a problem with hydraulic pressure and transmission fluid.

How often should a shift interlock solenoid be replaced?

The shift interlock solenoid does not require regular servicing and replacement. It is meant to last the lifetime of your car. 

Can I replace my shift interlock solenoid myself?

While technically possible to DIY, replacing the shift interlock solenoid can be complex and requires automotive knowledge. For safety and proper functioning, it's recommended to seek assistance from a qualified mechanic or professional for the best results.


Driving with a bad shift interlock solenoid is possible, but it's risky and not recommended. Your vehicle may get stuck in "Park," making it challenging to shift gears, and the safety feature preventing unintended gear shifts without pressing the brake pedal will be compromised. 
You should seek repairs promptly. Pay very close attention to any warning lights and trouble codes on your vehicle, especially the
Check Engine light
Signs of a malfunctioning shift interlock solenoid include being unable to shift out of "Park," even when pressing the brake pedal, or difficulty shifting between gears. You might also experience problems starting the vehicle.
You can get your solenoid replaced at authorized dealerships, local auto repair shops, and certified mechanics. Online platforms like GARAGEGUARD™ can also help you find vetted repair shops with fair price estimates and reviews to aid your decision-making.
