What does the transmission range sensor look like and where is located?

The transmission range sensor is typically a small, cylindrical or rectangular device, often featuring electrical connectors and may have a plastic or metal housing. It is usually located on or near the transmission assembly, often mounted on the side of the transmission case. Its position allows it to accurately detect the gear position and communicate this information to the vehicle's control module. In some vehicles, it may also be integrated with the transmission control unit.
