While it’s technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it’s best to replace a bad speed sensor as soon as possible.
What happens when a transmission sensor goes out?
Harsh or improper shifting
Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
How much does it cost to replace transmission sensor?
The average cost for transmission position sensor replacement is between $240 and $292. Labor costs are estimated between $125 and $157 while parts are priced between $116 and $134.
How do you fix a transmission sensor?
Replacing Your Transmission Speed Sensors
- Having found the sensor or sensors to be faulty, remove the connector between the sensor and the vehicle’s wiring.
- Using the proper socket, remove the faulty sensor.
- Connect the new sensor to the vehicle’s wiring.
- Install the new sensor.
- Lower your car.
- Start the engine.
Can a sensor cause transmission problems?
If it fails it can cause automatic transmission problems such as late harsh shifts, early soft shifts, or can result in no shifting at all. The mass airflow sensor is directly related to engine performance, so an issue may affect the drivability of the vehicle and a poor running engine.
Can a transmission go out without warning?
Luckily, transmission failure doesn’t usually happen without warning. There are several warning signs that your transmission’s going out.
How do you know if your transmission range sensor is bad?
Symptoms of a bad transmission range sensor:
- The car doesn’t start and will not move.
- Transmission shifts into an unexpected gear.
- The vehicle will go into limp mode.

What causes a transmission speed sensor to go bad?
Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
How do I fix code P0705?
What repairs can fix the P0705 code?
- Repairing an open or short in the TRS circuit.
- Replacing a faulty TCM.
- Replacing a faulty ECM.
- Changing the transmission fluid and filter.
- Adjusting the linkage connecting the shift lever on the transmission to the gear shifter inside the car.
Can ABS sensor cause transmission problems?
Yes, ABS does affect the transmission. Namely, the vehicle speed sensor is part of the ABS system. This is where your truck reads road speed. The transmission tuning is also based on road speed, and controls when the truck upshifts, downshifts, and when to lock the torque converter.
How do you check transmission sensors?
Place the sensor on a bench and check the pulsing AC voltage with the voltmeter as you slowly turn the gear by hand. If there is no voltage, the sensor may be defective. Install the new sensor into the transmission and replace the retaining bolt.
How do you check transmission?
Part 1 of 2: How to know if your automatic transmission is not working
- Step 1: Check the vehicle’s automatic transmission fluid. …
- Step 2: Test the brake pedal. …
- Step 3: Drive the car to test the transmission: Once you have conducted the stationary test, conduct a road test that will take the car through all the gears.

Where is the transmission sensor located at?
Note: The transmission speed sensor is located in the rear of a longitudinal mount transmission. For transaxles, the speed sensor is located on the long side of the output shaft. This would be the end of the transaxle that faces the front of the engine.
How many sensors are in a transmission?
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.
Can a bad battery affect your transmission?
A weak battery or low battery voltage can cause the transmission to enter into fail safe mode. This will cause a loss of power because the transmission will be locked in third gear.
Can a bad ground cause transmission problems?
Even more, bad engine grounds can also cause damage. If too much current tries to find proper ground unsuccessfully, it will choose an easy path through transmission components, transmission cable, throttle cable, wheel bearings and narrow ground wires, causing severe damage to these and other components.
