Description and Operation (F21): Description

The input speed sensor (NIN) is installed in the transaxle case.

This sensor detects the number of revolutions of the intermediate shaft's C2 drum as input shaft speed.

This signal is transmitted to the TCU. Based on those signals, the TCU controls engine torque, shift timing, and lock-up.
