Transmission Output Shaft Speed (OSS) Sensor

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The transmission output shaft speed (OSS) sensor is located on the extension housing. The OSS is a Hall-effect type sensor. The OSS reads the gear teeth on the park gear, different than the teeth used for park function. The OSS input to the powertrain control module (PCM) is used for shift scheduling, timing and TCC operation vehicle speed. The OSS has bi-directional capability and has a digital output.
