Dorman Transaxle Output Speed Sensor

Dorman Transaxle Output Speed Sensors: Precision Replacements You Can Trust

When a transaxle output speed sensor fails, the consequences ripple quickly through your vehicle's critical systems — the transmission control module loses its reference signal, shifting quality deteriorates, and in many cases a check engine light or erratic speedometer reading follows. Finding the right replacement matters, and Dorman has built its reputation in the aftermarket by engineering sensors that restore those functions reliably and without the dealership premium.

Dorman's lineup of transaxle output speed sensors falls under its well-known OE Solutions brand family — parts developed using state-of-the-art engineering tools to exactly replicate the OEM unit, then manufactured with modern tooling so the end product looks, fits, and functions as originally designed. Each sensor in this lineup carries the part-number series beginning with 917- (including popular part numbers such as 917-652, 917-653, 917-662, 917-664, 917-668, and 917-669), covering a wide range of front-wheel-drive applications where the transaxle combines the transmission and differential into a single housing.

What Sets Dorman's Sensors Apart

• Direct-fit design: Each sensor is designed to match the fit and function of the original sensor on specified vehicles, and is engineered for durability.
• Targeted replacement: These sensors are an ideal solution — a reliable replacement for an original part that has failed due to fatigue or electrical malfunction.
• Accurate signal output: Each sensor is engineered to precise standards to ensure accurate signal output, and is installed using the original hardware and plugs into the vehicle's existing wiring.
• Rigorous quality testing: Each part has undergone try-on validation and rigorous quality testing to ensure a quality fit and long service life.
• U.S.-based expertise: Products are backed by a team of product experts in the United States and more than a century of automotive experience.

Why the Transaxle Output Speed Sensor Matters

The transaxle output speed sensor monitors the rotational speed of the transaxle's output shaft and reports that data to the vehicle's powertrain control module (PCM) and transmission control module (TCM). This signal is essential not only for accurate speedometer readings but also for proper automatic transmission shift timing, traction control calibration, and ABS function on many platforms. A worn or failed sensor — whether from vibration fatigue, heat cycling, or electrical corrosion — can trigger false codes, rough shifts, or a complete loss of those systems. Dorman's replacement sensors match the fit and function of the original equipment sensor to restore critical speed-dependent vehicle functions, and each part has been engineered and rigorously tested to ensure reliable performance.

The Dorman Advantage in Sensor Engineering
