Durango 2002 Transmission Output Sensor Location Front Car

Introduction

The transmission output sensor (TOS) is a critical component of the transmission system in a 2002 Dodge Durango. It is responsible for sending data to the powertrain control module (PCM) about the speed and direction of the transmission output shaft. This information is used by the PCM to adjust the engine speed and transmission shift points, ensuring smooth and efficient operation of the vehicle.

Location of the TOS

The TOS is located on the front of the transmission, next to the oil pan. It is mounted on a bracket that is attached to the transmission case. The TOS is connected to the transmission output shaft by a gear or a belt.

How to Replace the TOS

Replacing the TOS is a relatively simple procedure that can be completed in about an hour. The following steps will guide you through the process:

1. Disconnect the negative battery terminal.
2. Raise the vehicle on jack stands and secure it.
3. Locate the TOS on the front of the transmission.
4. Disconnect the electrical connector from the TOS.
5. Remove the bolts that secure the TOS to the transmission case.
6. Pull the TOS out of the transmission.
7. Apply a thin layer of RTV sealant to the new TOS O-ring.
8. Insert the new TOS into the transmission.
9. Tighten the bolts that secure the TOS to the transmission case.
10. Connect the electrical connector to the TOS.
11. Lower the vehicle and connect the negative battery terminal.

Testing the TOS

Once the TOS has been replaced, it is important to test it to ensure that it is functioning properly. This can be done using a scan tool. The scan tool will display the data that is being sent by the TOS to the PCM. The data should show the speed and direction of the transmission output shaft.

If the TOS is not functioning properly, it can cause a variety of problems with the transmission, including:

* Shifting problems
* Loss of power
* Stalling
* Check engine light

If you are experiencing any of these problems, it is important to have the TOS checked by a qualified mechanic.

Conclusion

Replacing the TOS is a relatively simple procedure that can be completed in about an hour. However, it is important to ensure that the TOS is functioning properly, as a faulty TOS can cause a variety of problems with the transmission. If you are experiencing any problems with the transmission in your 2002 Dodge Durango, it is important to have the TOS checked by a qualified mechanic.
