Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery to avoid any electrical shorts.

2. Change Transmission Fluid

Sub-steps:
1. Remove the transmission drain plug and allow the old fluid to completely drain into a suitable container.
2. Replace the drain plug with a new gasket and torque it to the manufacturer's specifications.
3. Remove the transmission fluid fill plug.
4. Use a funnel to add new transmission fluid that meets Porsche specifications (typically, VW G052162 A2).
5. Check the fluid level using the dipstick, ensuring it is at the correct level when the engine is warm.

3. Replace Transmission Filter (if applicable)

Sub-steps:
1. Remove the transmission pan (if accessible) and clean the mating surfaces.
2. Replace the old transmission filter with a new one, ensuring it is seated properly.
3. Reinstall the transmission pan with a new gasket and torque the bolts to the specified value.

4. Test and Reprogram TCM (if necessary)

Sub-steps:
1. Reconnect the battery and start the engine.
2. Use a diagnostic scanner to check for TCM updates; perform any necessary reprogramming.
3. Clear any transmission-related error codes and take the vehicle for a test drive.
