The transmission range switch (also known as the neutral safety switch) is an important electronic sensor which tells your car’s powertrain module what gear your car is in. The transmission range switch prevents your car from starting unless your car is set to Park or Neutral.
Remove the nut securing the transmission control manual lever to the TR sensor. Loosen the two TR sensor retaining bolts. Align the TR sensor slots using the Transmission Range Sensor Alignment Tool T97L-70010-AH, or equivalent. Tighten the TR sensor retaining bolts to 7–9 ft.
The neutral safety switch is located in the linkage or inside the transmission case which allows the vehicle to shift gear.
Is a neutral safety switch the same as a transmission range sensor?
Sometimes called a neutral safety switch, the TRS is an electrical switch that tells your vehicle’s powertrain control module what gear your transmission is in when you turn the ignition key to the “on” position.

What happens when your transmission range sensor goes out?
The Transmission Range Sensor tells the PCM the position of the transmission shifter. The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
How do you test a transmission range switch?
What is another name for transmission range sensor?
Depending on the car in question, the Transmission Range Sensor may often be referred to as the neutral safety switch or PRNDL (Park-Reverse-Neutral-Drive-Low) input and can be found outside the transmission box or on the valve body.
Can neutral safety switch affect transmission?
A bad neutral safety switch cannot prevent you from starting your vehicle in most cases. But it may pose several issues to the engine and transmission. First, a defective neutral safety switch will disrupt the smooth gear operation. In other words, it’ll cause gear shifting issues.
What is the sensor on the transmission called?
Typically, two sensors communicate the transmission data to the vehicle’s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission’s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
What happens when a neutral safety switch goes out?
#4 – Cranks In Any Gear
Though much rarer than those conditions mentioned above, a neutral safety switch can also fail in the “functional” position, allowing a vehicle to crank no matter which gear the transmission is shifted to. This creates a potential hazard, warranting immediate replacement.
How do you reset a neutral switch?
How do I know if my safety switch is faulty?
“All you need to do is open your switchboard and press the “Test” button on each of your safety switches. If they are working properly, the power will instantly trip off on that circuit. If playback doesn’t begin shortly, try restarting your device.
Will an engine turn over with a bad neutral safety switch?
Engine will not crank in neutral but cranks in park
On the opposite side of the spectrum, when the vehicle cranks over when the transmission in in park but not neutral, it’s typically due to a faulty neutral safety switch.
Can you drive with a bad transmission range sensor?
No, but the behaviour you get when it’s bad might feel like a transmission problem. If that sensor isn’t working properly, all the computers will be completely confused about what is going on. The engine won’t be producing the torque it should be, and the transmission will be shifting early.
Does revving in neutral damage transmission?
Inside an automatic transmission are clutch packs and clutch bands that use friction to move certain parts when shifting. Revving the engine and then immediately putting the transmission into drive causes those clutch packs and clutch bands to prematurely wear out.
There is a fuse for the neutral safety switch in both automatic and manual transmissions. If this fuse blows, you will have to replace it as they work once only. A fuse in a neutral safety switch is there to protect the circuit from overloading.
How do I reset my electrical safety switch?
What to do
Try to reset the switch by flicking it back to the ON position.
If the switch does not reset unplug all the appliances (if on the power circuit) or turn off all lights (if on the light circuit).
Reset the switch.
Once the switch is reset, plug your appliances back in one at a time.
What happens if the fuse is connected to neutral?
The fuse wire is always connected in the live wire of the circuit because if the fuse is put in the neutral wire, then due to excessive flow of current when the fuse burns, current stops flowing in the circuit, but the appliance remains connected to the high potential point of the supply through the live wire.
How do you clean a neutral safety switch?
How long does it take to change a neutral safety switch?
Approximate time to complete: 1-hour Cost for Neutral Safety Switch: Low $25 High $160 Note: The cost for a neutral safety switch is normally between $30 and $60.
