Common Signs of a Failing Transmission Speed Sensor

A failing transmission speed sensor can significantly impact your vehicle’s performance, and recognizing the symptoms early can prevent more serious issues. One of the most noticeable signs is erratic or harsh shifting. If your vehicle experiences sudden or rough gear changes, it may be due to a malfunctioning speed sensor. Another clear indicator is issues with the speedometer. A faulty sensor can cause the speedometer to display incorrect speeds or even stop working altogether. Additionally, a malfunctioning speed sensor often triggers the check engine light on your dashboard, alerting you to potential problems. Transmission slippage, where your vehicle struggles to stay in gear or intermittently slips out of gear, is also a common sign of a failing speed sensor. If you are concerned about these symptoms and wondering where the output speed sensor is located, it is typically found on the transmission casing, often on the output shaft side. Addressing these signs promptly can help avoid more extensive transmission repairs.
