Turbine Shaft Speed (TSS) Sensor

WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The turbine shaft speed (TSS) sensor is a magnetic pickup, that sends a signal to the powertrain control module to indicate transmission turbine shaft speed. The TSS is mounted externally on the case. The PCM uses the TSS signal to help determine appropriate operating pressure and torque converter clutch (TCC) operation.
