However, Pinpointing the *exact* location without looking at your specific car is difficult. The location can vary slightly depending on the transmission type (automatic or manual). A diagram of your vehicle's transmission will be very helpful.
Replacing the Speed Sensor:
This is a moderately easy job, but requires some basic mechanical skills and tools.
Tools you'll likely need:
* Jack and jack stands: Essential for safely working underneath the car. Never work under a car supported only by a jack.
* Wheel chocks: Place these on the wheels opposite the side you're working on.
* Socket wrench and sockets: You'll need the correct size socket to remove the sensor's mounting bolt (likely a 10mm or 12mm, but check your specific car).
* Ratchet and extensions: For reaching the sensor.
* Wrench or pliers: May be needed to disconnect the electrical connector.
* New speed sensor: Purchase the correct replacement sensor from a reputable parts supplier. Make sure to get the correct one for your car’s transmission type.
* Penetrating oil (optional): If the bolt is seized, applying penetrating oil can help.
* Gloves: To keep your hands clean.
* Shop rags or paper towels: To clean up any spills or grease.
* Owner's manual (highly recommended): Look up any specific instructions or diagrams relevant to your car.
Procedure:
1. Safety First: Engage the parking brake firmly. Place wheel chocks on the wheels opposite the side you are working on. Raise the car using a jack and securely support it with jack stands. NEVER work under a car supported only by a jack.
2. Locate the Sensor: Find the speed sensor on the transmission case. Refer to a repair manual or online diagram specific to your 1996 Nissan Altima GXE for the exact location.
3. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the sensor.
4. Remove the Sensor: Use the appropriate socket wrench to remove the mounting bolt holding the sensor in place. If the bolt is stubborn, apply penetrating oil and allow it to soak for a few minutes.
5. Install the New Sensor: Carefully install the new speed sensor, ensuring it seats correctly. Tighten the mounting bolt to the manufacturer's specified torque (check your repair manual for this).
6. Reconnect the Electrical Connector: Connect the electrical connector securely.
7. Lower the Car: Carefully lower the car using the jack.
8. Test: Start the car and check your speedometer to ensure it's working correctly. If not, double-check your connections and the sensor installation.
Important Notes:
* Repair Manual: A repair manual specific to your 1996 Nissan Altima GXE is highly recommended. It will have detailed diagrams, torque specifications, and troubleshooting information.
* Transmission Type: The location and replacement procedure may vary slightly depending on whether you have an automatic or manual transmission.
* Professional Help: If you are not comfortable performing this repair yourself, it's best to take your car to a qualified mechanic.
Remember safety first! If you're unsure about any step, seek professional assistance. Improper repair could damage your transmission.
