OEM Transmission Speed Sensor for 1996-2004 Nissan Pathfinder models equipped with 2WD.

The Transmission Speed Sensor is a vital component of the vehicle's transmission system. It measures the speed at which the output shaft of the transmission is rotating and sends that information to the vehicle's engine control module (ECM). Based on this information, the ECM determines when to shift gears in an automatic transmission or adjust engine performance in a manual transmission.

Here are some signs that the transmission speed sensor may need to be replaced:

• Check engine light: A malfunctioning speed sensor can trigger the vehicle's check engine light to come on.
• Erratic shifting: If the speed sensor is not functioning correctly, the transmission may not shift smoothly or may shift at inappropriate times.
• Harsh shifting: A malfunctioning speed sensor can cause the transmission to shift harshly or with a noticeable delay.
• Speedometer not working: The speedometer in the vehicle relies on the information provided by the speed sensor. If the speed sensor is not functioning correctly, the speedometer may not work at all or may display an incorrect speed.
• Stalling: A malfunctioning speed sensor can cause the vehicle to stall, especially when coming to a stop.
