This summary uses the existing diagnostic information shown in full below.
This means that the sensor that checks how hot or cold the transmission fluid is, isn't working properly all the time. It's like a thermometer that's sometimes broken.
The Transmission Fluid Temperature Sensor B is responsible for monitoring the temperature of the transmission fluid. An intermittent circuit means that the sensor's electrical signals are not consistent, which can affect transmission performance.
The P2744 code indicates that the Transmission Control Module (TCM) has detected an intermittent fault in the circuit for the Transmission Fluid Temperature Sensor B. This sensor provides critical data for managing the transmission's operation, and an intermittent signal can lead to incorrect transmission behavior.
• Check Engine Light is on
• Transmission may overheat
• Erratic or harsh shifting
• Faulty Transmission Fluid Temperature Sensor B
• Wiring issues such as damaged wires or poor connections
• Faulty Transmission Control Module (TCM)
Transmission Control Module (TCM): A computer that controls the transmission's operation.
Intermittent Circuit: An electrical circuit that occasionally fails to function properly.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the sensor for proper resistance and voltage.
• Repair or replace damaged wiring or connectors.
• Replace the Transmission Fluid Temperature Sensor B if faulty.
• Reprogram or replace the TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check and maintain transmission fluid levels.
• Inspect wiring and connectors for wear and tear.
• Schedule routine transmission maintenance.
Sensor Issue
• Avoid driving aggressively until the issue is resolved.
• Monitor transmission temperature if possible.
• Consult a professional mechanic for diagnosis and repair.
Check with your vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with vehicles that have high mileage or poor maintenance history.
Moderate – Addressing this issue promptly can prevent further transmission damage.
Operating a vehicle with transmission issues can lead to safety hazards. Ensure repairs are conducted by a qualified professional.
• Vehicle at normal operating temperature
• Transmission under load
The Transmission Fluid Temperature Sensor B is typically located inside the transmission or on the transmission fluid pan.
Q: Can I drive with a P2744 code?
A: It's not recommended as it can lead to transmission damage. Get it checked as soon as possible.
Q: How do I know if my transmission fluid temperature sensor is bad?
A: Symptoms include erratic shifting, transmission overheating, and the Check Engine Light being on.
