If you’re having trouble with your speedometer or experiencing transmission performance issues in your Chevrolet 4WD vehicle, knowing where the speed sensor is located can be a game changer. The 4L60E transmission is commonly found in many Chevrolet trucks and SUVs, so let’s dive into where you can find this critical component.
What is the Speed Sensor?
The speed sensor measures the rotational speed of the transmission output shaft. This information is crucial for the engine control module (ECM) to manage engine performance and shifting behavior. A malfunctioning speed sensor can lead to incorrect speed readings and poor transmission performance.
Location of the Speed Sensor
In vehicles equipped with the 4L60E transmission, the speed sensor is typically located:
On the rear of the transmission: Look for a small, cylindrical sensor mounted on the transmission case.
Near the tailshaft: You should find it near where the driveshaft connects to the transmission, specifically on the driver’s side towards the back.
Accessible from the underside: To get a clear view or access the sensor, you may need to raise the vehicle and utilize a jack stand for safety.
Steps to Locate the Speed Sensor
Ensure Safety: Before you start, make sure the engine is off, and the vehicle is securely raised.
Identify the Transmission: Confirm that your vehicle has the 4L60E transmission by checking your owner’s manual or by looking for identification tags on the transmission.
Inspect the Area: Get under the vehicle and look towards the rear of the transmission, searching for the speed sensor. It should have wiring harnesses connected to it.
Disconnect and Test: If you’re troubleshooting, you can disconnect the wiring and test the sensor with a multimeter to see if it’s functioning correctly.
Troubleshooting Tips
Check Electrical Connections: Sometimes, the issue may arise from loose or corroded connections rather than a faulty sensor.
Scan for Codes: Using an OBD-II scanner can help identify if there are any codes related to the speed sensor or transmission.

By knowing where the speed sensor is located and understanding its role, you can better troubleshoot any issues related to your vehicle’s speed and transmission performance. Good luck with your repairs, and feel free to ask if you have more questions!
To find the speed sensor on a 4WD with a 4L60E transmission, you’ll want to start by looking at the driver’s side of the transmission. It’s usually located near the tail shaft area. Grab a flashlight for better visibility!
You’ll need a socket set and possibly a torque wrench. Having a diagram of the transmission layout can also be really helpful to pinpoint the sensor’s location easily.
Be gentle with the connectors. Use a small flat-head screwdriver to pry up the locking tab. Make sure to clean the area around it before pulling to avoid debris entering the transmission.
Hi everyone! To start off, the speed sensor on a 4L60E is typically located on the passenger side of the transmission. Make sure you disconnect the battery before working on it to ensure safety.
You’ll need a basic socket set, a screwdriver, and probably a torque wrench. Don’t forget some gear oil to replace any that may spill out, plus a safety lift to ensure you work comfortably under the vehicle!
Generally, the torque specs for the speed sensor bolts are around 11 lb-ft. It’s always a good idea to double-check the manual for your specific vehicle model just to be sure.
It is straightforward, but make sure the area is clean. Any debris can cause issues when you reinstall the new sensor. Also, take care with the electrical connector; a gentle touch goes a long way!
