2000 Lincoln Town Car Transmission Range Sensor

Purpose

The transmission range sensor (TRS) is a component of the transmission that provides the powertrain control module (PCM) with information about the selected gear range. This information is used by the PCM to control the transmission’s shift pattern and to provide the driver with feedback on the current gear range.

Location

The TRS is located on the side of the transmission, near the shifter linkage. It is typically held in place by a few bolts.

Symptoms of a Bad TRS

There are a few symptoms that may indicate a bad TRS, including:

• The transmission may not shift properly.
• The transmission may shift erratically.
• The transmission may not shift into the desired gear range.
• The transmission may slip out of gear.
• The transmission may make a grinding noise when shifting.

Testing the TRS

There are a few ways to test the TRS. One way is to use a multimeter to measure the resistance between the TRS terminals. The resistance should be within a specific range, which can be found in the vehicle’s service manual. Another way to test the TRS is to use a scan tool. A scan tool can be used to read the TRS data and to determine if it is functioning properly.

Replacing the TRS

If the TRS is found to be defective, it will need to be replaced. The replacement procedure is relatively straightforward and can be completed in a few hours. Here are the steps involved in replacing the TRS:

1. Disconnect the negative battery terminal.
2. Remove the air filter housing.
3. Unbolt the TRS from the transmission.
4. Disconnect the electrical connector from the TRS.
5. Install the new TRS.
6. Tighten the TRS bolts.
7. Connect the electrical connector to the TRS.
8. Reinstall the air filter housing.
9. Connect the negative battery terminal.

Conclusion

The TRS is an important component of the transmission. If it fails, it can cause a variety of problems. If you are experiencing any of the symptoms listed above, it is important to have the TRS tested. If the TRS is found to be defective, it will need to be replaced.
