The speed sensor on a 4L60E transmission is located in the tailshaft housing, just behind the output shaft. It consists of a toothed reluctor wheel that turns with the output shaft, and a magnetic pickup coil that produces an AC signal as the teeth on the reluctor wheel pass by. This signal is sent to the transmission control module (TCM), which uses it to determine vehicle speed.
The speed sensor on a 4L60E transmission is located in the tailshaft. It is a two-wire sensor that measures the speed of the transmission output shaft. The signal from the sensor is used by the transmission control module to determine when to shift gears.

4L60E Bad Speed Sensor Symptoms
If your 4L60E equipped vehicle is experiencing any of the following symptoms, it may be due to a bad speed sensor:
1. Check Engine Light is illuminated
2. Transmission does not shift properly
3. Vehicle speedometer does not work correctly
4. Loss of power while driving uphill
5. Slipping or no reverse gear
A bad speed sensor on your 4L60E transmission can cause all sorts of problems. The most common symptom is the Check Engine Light being illuminated on the dash. This can be accompanied by the transmission not shifting properly, or the vehicle’s speedometer acting erratically or not working at all.
In some cases, there may also be a loss of power while driving uphill, or slipping and no reverse gear. If you are experiencing any of these issues, it is important to have your vehicle checked out by a qualified mechanic as soon as possible to avoid further damage to your transmission.
4L60E Speed Sensor to Cable
If you’re having transmission problems in your GM vehicle equipped with the 4L60E automatic transmission, one possible cause could be a faulty speed sensor. The speed sensor is what tells the transmission computer the speed of the vehicle so it can make shifting decisions accordingly. If it’s not working properly, it can cause all sorts of shifting issues.
In this article, we’ll show you how to replace the speed sensor on a 4L60E transmission. This is a pretty straightforward job that most anyone can do with some basic hand tools. We’ll also give you some tips on diagnosing other potential causes of 4L60E transmission problems.
Replacing the Speed Sensor
1) Disconnect the negative battery cable. 2) Raise and safely support the vehicle.
3) Remove the wheel and tire assembly for better access to the area where the speed sensor is located. 4) Using a small pick or needle-nose pliers, remove the electrical connector from the speed sensor (it just pops off). 5) Unscrew and remove the two bolts holding the speed sensor in place using a 10mm socket or wrench (one bolt is located above and one below the sensor).
6) Pull out old speed sensor and insert new one in its place making sure it’s seated properly against its gasket/seal. 7) Re-install both bolts finger-tight until they are flush with their respective surface then tighten them down using your 10mm socket or wrench (don’t overtighten!). 8) Reconnect electrical connector to new speed sensor
4L60E Speed Sensor Conversion
In 1993, GM introduced the 4L60E transmission. This was a four-speed automatic that replaced the older Turbo Hydramatic 400. The 4L60E was significantly smaller and lighter than the TH400, making it ideal for use in smaller vehicles.
However, one downside to the new transmission was its lack of a speed sensor.
The speed sensor on a car is responsible for sending information to the computer about how fast the car is going. Without this information, the computer cannot properly adjust fuel and ignition timing.
This can lead to decreased performance and fuel economy.
Fortunately, there is an easy way to convert your 4L60E to use a speed sensor. All you need is a new output shaft with a built-in speed sensor reluctor ring (this can be sourced from most aftermarket transmission parts suppliers) and a few other simple parts.
With this conversion kit installed, your 4L60E will function just like it would have if it had come with a factory speed sensor.
4L60E Input Speed Sensor Test
In order to test the input speed sensor on your 4L60E transmission, you will need a few tools. First, you will need a multimeter. Second, you will need a small Phillips head screwdriver.
Third, you will need access to the transmission.
To begin, locate the input speed sensor on the side of the transmission nearest the engine (it will have two wires going to it). Using the Phillips head screwdriver, loosen the retaining clip that holds the sensor in place and remove the sensor.
Next, take your multimeter and set it to read AC voltage. If your multimeter does not have an AC setting, then you can use DC voltage but be aware that there may be false readings due to electrical interference. With the leads from your multimeter touching the exposed metal terminals on the back of the input speed sensor, start the engine.
The reading on your multimeter should fluctuate between 0 and 5 volts; if it does not fluctuate or if it reads 0 volts constantly then there is a problem with your input speed sensor and it needs to be replaced.

Where are the Transmission Speed Sensors Located?
The transmission speed sensors are located in the transmission. The sensor measures the speed of the transmission and sends a signal to the computer. The computer uses this information to control the shifting of the gears.
What are the Symptoms of a Transmission Speed Sensor?
A transmission speed sensor is a type of speed sensor that is used to monitor the speed of a vehicle’s transmission. Transmission speed sensors are usually located in the transmission, near the front or rear of the engine. The most common symptom of a faulty transmission speed sensor is a check engine light that comes on when the vehicle is driven.
Other symptoms may include an erratic or jerky shifting of gears, or a delay in acceleration. If you suspect that your vehicle may have a faulty transmission speed sensor, it is important to have it checked by a qualified mechanic as soon as possible.
Which Speed Sensor Controls the Transmission?
The speed sensor that controls the transmission is located in the transmission itself. This sensor monitors the speed of the transmission’s input shaft and sends a signal to the transmission control module (TCM). The TCM uses this signal to determine when to shift gears.
How Do I Know If My Speed Sensor is Not Working?
If your speed sensor is not working, you will likely experience one or more of the following symptoms:
– Your vehicle’s speedometer may not work properly.
– You may notice that your vehicle takes longer to accelerate than usual.
– Your car may feel like it is “dragging” when you try to stop.
If you are experiencing any of these issues, it is important to have your speed sensor checked as soon as possible. A faulty speed sensor can cause problems with your car’s transmission and engine, so it is important to get it fixed sooner rather than later.
Conclusion
On a 4L60E transmission, the speed sensor is located on the driver’s side of the transmission, just below the shift lever. It is a small black sensor with two wires coming out of it.
