Description and Operation (F21): Description

• The transmission wires are installed on the transaxle case as the grouped connectors of the oil temperature sensor, speed sensors, and solenoids.
• The oil temperature sensor (A), which is integrated with the transmission wires, is installed on the front valve body. It directly detects the oil temperature within the hydraulic pressure control circuit and transmits a signal based on that temperature to the TCU. In response to changes in oil temperature, the TCU controls gear shifting for smooth shifting across a wide range of temperatures.
