All automatic transmission vehicles have a safety switch in place that only allows them to start if they are in park or neutral gars. The transmission position sensor, also called the transmission position switch, ensures the vehicle is in neutral or park when the vehicle is started up. If the sensor reads the vehicle is in drive or any other gear, the car is equipped with a safety shutdown that will not allow the vehicle to start at all.

The transmission position sensor is located on the side of the transmission. Power is not sent to the starter circuit unless the sensor reads the vehicle is in neutral or park. Furthermore, the vehicle will not even crank to prevent vehicle movements. Over time, the transmission position sensor can go bad or fail. This can mean the vehicle may start in a gear other than park or neutral, which can be a dangerous situation.

Sometimes a sensor problem can mimic other problems, such as a dead battery. If the sensor has completely failed and the vehicle will not start at all, it may be hard to tell the difference between the sensor and a dead battery. After jumping the vehicle and it still does not turn on, the problem may be with the transmission position sensor, but it is best to have it looked at by a mechanic to be sure.

Since the transmission position sensor can fail and go bad over time, it is important to recognize the symptoms it gives off before it completely fails.

Signs your transmission position sensor needs to be replaced include:

  • The engine will start while the gear is in drive or reverse

  • The vehicle will start in neutral, but not park

  • The vehicle will not start at all, not even turn over

This is a repair that needs to be attended to right away as failing to do so can cause your vehicle to be inoperable. Have a certified mechanic replace the failing transmission position sensor switch to eliminate any further problems with your

Mitsubishi Diamante - Transmission Position Sensor (Switch) - Jacksonville, Florida
He showed up right on time and took his time going thru service and other facets of my vehicle that weren't even being serviced. He went Above and Beyond by helping me with the hood of the car-the latch had broke and he jimmied it where it could open and close after it was in a fender bender-it had Nothing to do with why he was there, but he made sure it was road worthy...We definitely found Our Mechanic in Mathew!
