This summary uses the existing diagnostic information shown in full below.
Your car's computer tried to learn how to move a part in the transmission, but it couldn't figure it out.
The vehicle's transmission control module (TCM) is unable to learn the calibration for shift fork B, which is necessary for proper gear shifting.
The P288D code indicates that the TCM has failed to learn the calibration of shift fork B. This fork is responsible for engaging specific gears in a dual-clutch transmission. The failure to learn calibration can result in improper gear engagement and shifting issues.
• Check Engine Light is on
• Difficulty in shifting gears
• Transmission slipping or not engaging
• Faulty shift fork B
• Transmission control module malfunction
• Wiring issues or poor connections
TCM: Transmission Control Module
Shift Fork: A component in the transmission that helps engage gears
• Check for other related transmission codes
• Inspect the wiring and connections to the TCM
• Test the shift fork B for mechanical issues
• Reprogram or replace the TCM
• Repair or replace faulty wiring
• Replace shift fork B if damaged
• OBD-II scanner

• Regular transmission maintenance
• Ensure proper software updates for the TCM
• Avoid aggressive driving habits
Transmission Calibration Issue
• Avoid driving the vehicle if shifting issues are severe
• Consult a professional mechanic for diagnosis and repair
Check if the vehicle's transmission is covered under the manufacturer's warranty.
This code is commonly seen in vehicles with dual-clutch transmissions, particularly in certain Ford and Volkswagen models.
Moderate – Address the issue promptly to avoid further transmission damage.
Driving with transmission issues can be dangerous. Ensure repairs are made by a qualified technician.
• Vehicle at operating temperature
• Transmission in learning mode
Shift fork B is located inside the transmission housing.
Q: Can I drive with a P288D code?
A: It's not recommended as it can lead to further transmission damage.
Q: How is the calibration learned?
A: The TCM uses sensors to learn the position and operation of the shift fork during normal driving conditions.
