Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery's negative terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, catch basin
Remove the transmission fluid pan using a socket set.
Allow fluid to drain completely into a catch basin.
Inspect the old fluid for metal shavings or discoloration.
Replace with new transmission fluid as per manufacturer specifications (usually VW G 052 162 A2).
Reinstall the pan with a new gasket and torque bolts to manufacturer specifications.

3. Inspect and Replace Transmission Filter

Remove the transmission pan (if not already done in the previous step).
Locate the transmission filter and remove it.
Install a new filter, ensuring it is seated properly.
Reattach the pan and torque to specifications.

4. Reprogram or Reset TCM (if necessary)

Tools Required: OBD-II scanner
Reconnect the battery.
Use an OBD-II scanner to reset the TCM and clear any fault codes.
Follow any specific manufacturer procedures for reprogramming the TCM if needed.

5. Inspect and Replace Mounts (if necessary)

Tools Required: Jack, jack stands, socket set
Lift the vehicle using a jack and secure it with jack stands.
Inspect the motor and transmission mounts for cracks or wear.
Replace any damaged mounts with new ones, ensuring proper alignment.
