3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Repair Instructions

Important:

* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) following all transmission related repairs.

* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:

Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General

Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

Circuit/System Description

The automatic transmission fluid temperature sensor provides transmission fluid temperature to the transmission control module (TCM). The TCM

supplies a 5 V reference signal to the sensor. The automatic transmission fluid temperature sensor is a variable resistor that measures the

temperature of the transmission fluid and is a thermistor, or a resistor that changes value when the temperature changes. The sensor has a negative

temperature coefficient. This means that as the temperature increases the resistance decreases and vice versa. The TCM will compare the

temperature difference between the engine coolant temperature sensor and the automatic transmission fluid temperature sensor to determine if the

temperatures are within an acceptable operating range of each other. This fault is handled inside the TCM and no external circuits are involved.
