Common Questions

What does U0713 mean and how does it affect my car?

The U0713 code indicates a communication problem between your car's Transmission Control Module and other essential control units. This can lead to poor shifting performance, hesitation during acceleration, and can even put your vehicle in a limited power mode. Addressing this issue quickly is crucial to maintaining your vehicle's performance and safety.

What are the most common causes of U0713 and how much does it cost to fix?

Common causes of U0713 include a faulty Transmission Control Module, damaged wiring, or software glitches. Repair costs can range significantly based on the diagnosis, typically from $150 for simple wiring repairs up to $1,200 for TCM replacement.

Can I drive my car with U0713 or should I stop immediately?

While it may be possible to drive short distances with a U0713 code, it's not advisable. Continuing to drive can lead to more severe transmission issues and expensive repairs. It's best to address this code as soon as possible.

How can I diagnose U0713 myself using GeekOBD APP?

Using the GeekOBD APP, you can perform a full scan to retrieve the U0713 code and any other related codes. Review the freeze frame data to understand the conditions under which the code was triggered, and check for any additional symptoms that may provide clues for diagnosis.

What vehicles are most commonly affected by U0713?

The U0713 code is frequently encountered in vehicles like the 2015-2019 Ford F-150 and certain models from other manufacturers. Be sure to check for any recalls or Technical Service Bulletins (TSBs) related to transmission control issues for your specific vehicle.

How can I prevent U0713 from happening again?

Regular maintenance is key to preventing U0713. Ensure your vehicle's software is up-to-date, conduct routine inspections of the wiring and connectors, and address any symptoms of transmission issues promptly.

What is U0713?

The U0713 diagnostic trouble code is a communication error between the Transmission Control Module (TCM) and other control modules within the vehicle, particularly in models like the 2015-2019 Ford F-150. This code indicates that the TCM is not receiving expected signals from the Engine Control Module (ECM) or other related systems. When this happens, the vehicle may exhibit erratic shifting patterns, a lack of responsiveness, or even enter 'limp' mode, which restricts the vehicle's performance to prevent further damage. In real-world terms, this can lead to frustrating driving experiences as your truck might hesitate or stop shifting properly, affecting overall driving safety and enjoyment. Left unchecked, a U0713 code could potentially lead to more severe transmission issues, increased repair costs, and reduced vehicle reliability. It's important for car owners to take this code seriously, as it not only impacts vehicle performance but also raises concerns about safety and long-term functionality.

System: U - Network (Communication, CAN Bus)

Symptoms

Common symptoms when U0713 is present:

  • Check engine light stays on constantly, indicating an underlying issue with transmission communication.
  • Engine hesitates during acceleration, making it difficult to maintain speed or respond quickly to throttle inputs.
  • Fuel economy decreased by 10-15%, as the vehicle struggles to shift properly and optimize engine performance.
  • Rough or erratic shifting patterns, where the transmission may shift too early or too late.
  • Transmission may go into 'limp mode', limiting power and speed to protect the vehicle from further damage.

Possible Causes

Most common causes of U0713 (ordered by frequency):

  1. Faulty Transmission Control Module (TCM) - This is the most common cause, making up about 40% of U0713 cases. A malfunctioning TCM can fail to communicate with other modules, leading to this error code.
  2. Corroded or damaged wiring harness - Approximately 30% of cases stem from wiring issues that disrupt communication between the TCM and ECM. Regular inspections can help prevent this.
  3. Software glitches - Around 20% of U0713 codes result from outdated or corrupt software in the TCM or ECM. Keeping your vehicle's software updated through your dealer can mitigate this risk.
  4. Less common but serious cause includes a failed ECM, which can lead to multiple error codes and complex repairs.
  5. Rare but possible cause could be a fault in the CAN bus system, which is responsible for data communication between modules.
