A faulty TRS can cause a variety of symptoms, including:

* Difficulty shifting gears
* Transmission slipping out of gear
* Erratic transmission behavior
* Illuminated Check Engine Light

Causes of a Faulty Transmission Range Sensor

There are several factors that can cause a TRS to fail, including:

* Wear and tear
* Electrical problems
* Mechanical damage

Diagnosis of a Faulty Transmission Range Sensor

Diagnosing a faulty TRS requires a qualified technician with specialized tools. The technician will typically begin by checking for any diagnostic trouble codes (DTCs) that may be stored in the TCM. They will then perform a physical inspection of the TRS and its wiring harness.

Replacement of a Faulty Transmission Range Sensor

If the TRS is found to be faulty, it will need to be replaced. This is a relatively simple procedure that can be performed by a qualified technician in about an hour.

Cost of Replacing a Transmission Range Sensor

The cost of replacing a TRS will vary depending on the labor rates in your area and the specific parts used. However, you can expect to pay between $200 and $500 for the repair.
