COUPLER COMPONENT (TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR) OUTLINE [AY6A-EL, AY6AX-EL]

id0517k3224600

• The coupler component are installed on the transaxle case as the grouped connectors of the TFT sensor, input/turbine speed sensor, VSS and solenoids.
• The TFT sensor, which is integrated with the coupler component, is installed on the front valve body. It directly detects the TFT within the hydraulic pressure control circuit and transmits a signal based on that temperature to the TCM. In response to changes in oil temperature, the TCM controls gear shifting for smooth shifting across a wide range of temperatures.
