Turbine Shaft Speed (TSS) Sensor and Primary Variator Speed Sensor

The turbine shaft speed (TSS) sensor and primary variator speed sensor are housed in the transmission control module (TCM). The TCM is attached to the mechatronic unit. Both speed sensors are Hall-effect.

The primary variator speed sensor reads the primary pulley shaft speed.

The speed sensor for the primary pulley is part of the transmission control module. It is an non-contact Hall sensor which measures the rotational speed of the primary pulley.
