What happens when a transmission speed sensor goes bad?
Therefore, a failing speed sensor will have a direct impact on automatic transmission operation. One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.
Where is the transmission speed sensor located?
Locate the transmission speed sensors, they’ll be near the front and rear of the transmission housing. Consult the repair manual for your car. Place bucket or oil drain pan underneath the sensor, there will be some oil that drains out.
How much does it cost to replace a transmission speed sensor?
The DIY cost for replacing a speed sensor is the cost of the sensor. Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45.
How do you test a transmission speed sensor?
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 know if your transmission speed sensor is bad?
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.
What is the difference between vehicle speed sensor and transmission speed sensor?
Vehicle Speed Sensor Operation. If you noticed, I’ve used the words, transmission speed sensor and vehicle speed sensor so far. The only difference between the two is what the manufacturer decides to call it. In either case, the faster the transmission output shaft moves, the more voltage the sensor produces.
What does a transmission speed sensor control?
The transmission speed sensor detects how fast your car is traveling on the road. When you look at your dashboard, you can see the tachometer representing the engine speed and the speedometer representing the transmission speed. Both sensors are constantly communicating with the engine control unit of the vehicle.
Can I drive with a broken speed sensor?
That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. If the wheel speed sensor becomes damaged or wears out, initially you probably won’t notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.
How long does it take to replace a transmission sensor?
It can take a bit longer depending on the level of damage. Some professional technicians complete the entire replacement task in two or three hours.
Can a speed sensor be fixed?
Transmission speed sensors cannot be repaired, only replaced. While transmission speed sensor failure is not uncommon, many other problems can present similar systems such as ABS sensor failures. A full professional inspection will be needed to determine the actual cause of the problem.
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.
Does the speedometer affect the transmission?
The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the vehicle speed sensor is faulty, however, at times, the driven gear inside the transmission is at fault.
Can you clean a transmission speed sensor?
The transmission speed sensor measures the RPMs of the shaft of the transmission. In this case, the sensor may not have to be replaced as the sensor can be cleaned off. Yet, only a mechanic should make that determination because there may be damage to the electrical part of the sensor.
How do you check a transmission control module?
The transmission control module can often be found below the cover at the back of the transmission case. It should be just below the engine control module’s position. Sometimes it’s found under the center console in the interior or even under the hood near the battery or inner fender panel.
Can electrical problems 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.
