How Much Does a Neutral Safety Switch Replacement Cost?
Neutral Safety Switch Replacement Service and Cost
When starting a vehicle, if the automatic transmission is not in neutral or park, the neutral safety switch will prevent the engine from starting.
To protect the vehicle, there is a switch installed on most automatic and dual clutch transmissions which disallows the engine from starting when the transmission is not placed in neutral or park. Some models use input from the transmission control unit to determine the vehicle's transmission position, but others use a physical switch. Both systems function to interrupt the starting circuit when the transmission is not in park or neutral.
Driving with a faulty neutral safety switch is generally impossible, but if the vehicle will start and change gears like normal, driving should not pose any issues. If the vehicle will not start, it will require a tow to a repair facility.
MAF sensors do tend to fail sometime in many vehicles. Failure rates are highest between 100,000 and 150,000 miles, but this is only an average. The sensor can also be damaged by road debris in many vehicles, or anytime the transmission is serviced or repaired. Lastly, a collision may cause a physical or electrical fault in the neutral safety switch. Vehicles with internal neutral safety switches will benefit from proper maintenance, and may fail prematurely when the transmission is neglected.
Neutral Safety Switch Replacement Repair Information
The neutral safety switch is quickly diagnosed by testing the switch, and related components attached to the gear selector inside the vehicle. A faulty neutral safety switch will most likely be removed and bench tested for confirmation of failure.
Replacement of a steering knuckle on most vehicles is an advanced DIY repair that requires tools, equipment, and experience necessary to remove pressed hubs and bearings (including snap rings that retain the bearings), and to press the components into the new steering knuckle. The ball joints and tie rod end also need to be separated. The vehicle needs to be safely lifted in the air with a jack and jack stands to perform this repair. If you are not comfortable with these repair procedures, it would be wise to find a professional technician for the job.
We always recommend contacting the dealership parts department for revised part numbers. There may be a new part number for the neutral safety switch, and possibly the transmission fluid. When new part numbers are issued, this may be due to a redesigned part that fixes known flaws, or an update. Aftermarket sensors may not have these benefits.
There are many types of transmission fluids, and they are not typically interchangeable. Consulting the owner's manual for your vehicle is the best way to ensure you have the correct fluid for your transmission. If improper transmission fluid is added, the resulting damage could be severe.
Replacing the neutral safety switch at home could be done for more experienced DIYers. The person completing the repair must have an understanding of how the switch functions, how the switch is sealed against transmission fluid leaks, and how to diagnose the switch. If any of these areas are unclear, or if the switch is internal to the transmission, a trusted professional should complete this repair.
