why is my Volkswagen Golf Eighth Generation (2020-present) not shifting properly

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shock.
• Allow the vehicle to cool if the engine has been running.

2. Fluid Change

• Tools Required: Socket set, transmission fluid pump, drain pan, funnel
• Remove the transmission pan using a socket wrench and let the old fluid drain completely into a pan.
• Replace the transmission filter if applicable.
• Reinstall the transmission pan using a new gasket and torque bolts to manufacturer specifications (typically around 8-10 Nm).
• Fill the transmission with the appropriate type and amount of new transmission fluid as specified in the owner’s manual.

3. Transmission Control Module (TCM) Reset

• Tools Required: OBD-II scanner
• Reconnect the battery terminal.
• Use the OBD-II scanner to clear any stored transmission error codes.
• Perform a TCM reset to recalibrate the transmission adaptations (if applicable).

4. Test Drive

• Take the vehicle for a test drive under various driving conditions to ensure the shifting issue has been resolved.
• Monitor for any warning lights or abnormal behavior during the drive.
