how to fix P0700 transmission code in Volkswagen Golf MK6 (2009-2014)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to prevent electrical shorts.

2. Fluid Change

• Tools Required: Socket set, transmission fluid pump, torque wrench, drain pan.
• Remove the transmission pan bolts using a socket wrench.
• Carefully lower the transmission pan and allow the fluid to drain completely into a drain pan.
• Inspect the transmission filter and replace it if necessary.
• Clean the transmission pan and apply new gasket sealant if needed.
• Reinstall the transmission pan and torque bolts to the manufacturer's specifications (usually around 8-10 Nm).

3. Electrical Inspection

• Tools Required: Multimeter, wiring diagram.
• Reconnect the battery and turn on the ignition (do not start the engine).
• Use a multimeter to test the voltage at the TCM connector. Compare results with specifications in the wiring diagram.
• Repair or replace any damaged wiring or connectors as necessary.

4. TCM Reprogramming (if applicable)

• Tools Required: OBD-II scanner capable of programming.
• If the TCM is determined to be faulty or has been replaced, use the OBD-II scanner to reprogram the TCM as per manufacturer instructions.

5. Final Assembly

• Refill the transmission with the correct type and amount of fluid (consult the owner's manual for specifications).
• Start the engine and let it idle, then cycle through the gears (P, R, N, D) to ensure fluid circulates properly.
• Check for leaks around the pan and connectors.
