Automatic Transaxle Input (Shaft) Speed Sensor

Provides transaxle input speed data to the TCM for determining shift patterns and TCC apply/release, and gear ratio

Engine Coolant Temperature Sensor

• Provides coolant temperature data to the TCM for determining initial TCC engagement
• An incorrect engine coolant temperature sensor input could cause an incorrect initial TCC apply.

Engine Speed

• The ignition module provides engine speed data to the TCM.
• The TCM uses engine speed information for controlling wide open throttle shifts and the TCC pulse width modulation (PWM) solenoid duty cycle.

Stop Lamp Switch

• Provides brake apply information to the TCM for controlling TCC apply and release
• An incorrect TCC stop lamp switch input could cause an incorrect TCC apply or release.

Transaxle Fluid Temperature (TFT) Sensor

• Provides transaxle fluid temperature information to the TCM for determining alternate shift patterns and TCC apply during high temperature conditions, hot mode operation
• An incorrect transaxle temperature sensor input could cause altered shift patterns, poor shift quality, and incorrect TCC apply.
