• Ensure the vehicle is on a level surface and secure it with jack stands if needed.

2. Fluid Change

• Tools Required: Socket set, transmission fluid funnel, container for old fluid.
• Drain the old transmission fluid by removing the transmission pan bolts and tilting the pan to allow fluid to escape.
• Inspect the transmission filter; replace it if it is clogged or damaged.
• Reinstall the transmission pan with a new gasket, ensuring all bolts are tightened to the manufacturer's torque specifications (typically around 8 Nm).
• Refill the transmission with the recommended type of fluid (usually VW G 052 162 A2 or equivalent) through the dipstick or fill port until the correct level is achieved.

3. TCM Inspection and Repair

• Tools Required: OBD-II scanner, multimeter, screwdriver set.
• Remove the TCM from its mounting location after disconnecting the electrical connectors.
• Inspect the TCM for any physical damage; if damage is found, replace the TCM.

• Reinstall the TCM and reconnect all wiring.

4. Solenoid Check

• Tools Required: Multimeter, socket set.
• Locate the transmission solenoids and disconnect their electrical connectors.
• Use a multimeter to check for resistance; compare the values against manufacturer specifications.
• Replace any faulty solenoids.
