Detailed Product Description

This Dorman 917-673 automatic transmission output shaft speed sensor is engineered and tested to deliver reliable signal performance in the transmission system. It is a direct replacement for the original sensor used on a wide range of Ford and Mazda trucks and SUVs, including Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Mazda B2300, Mazda B2500, Mazda B3000, and Mazda B4000. This part cross-references Standard Ignition SC370 for the same application.

By restoring accurate output shaft speed input, this sensor helps the transmission control system maintain proper shifting behavior and other speed-dependent functions. The Dorman 917-673 is a practical choice for drivers searching for a transmission output shaft speed sensor for 1997-2011 Ford Ranger or a replacement automatic transmission speed sensor for Mazda B3000 and B4000 models.

Common Issues This Sensor Can Address

• Erratic or delayed shifting caused by an inaccurate transmission speed signal
• Transmission warning lights related to speed sensor faults
• Loss of speed-dependent vehicle functions tied to transmission output shaft data
• Intermittent drivability concerns from a failing automatic transmission speed sensor
• Diagnostic trouble codes associated with output shaft speed sensor performance

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a single connector, blade terminals, and a square connector profile. Confirm the transmission application against the vehicle’s original part number and inspect the connector and wiring for corrosion or damage before installing the replacement sensor.

Quality Assurance

Dorman engineers and rigorously tests this sensor to support dependable operation and OE-style fitment on the listed Ford and Mazda applications. It is built to restore the original sensor’s function in the transmission speed sensing circuit.
