my Porsche 911 992 (2019-Present) transmission slips when shifting gears what's wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the battery to prevent electrical shorts.

2. Fluid Change

• Sub-steps:
  1. Remove the transmission fluid pan using a socket set, ensuring to catch any fluid in a drain pan.
  2. Replace the transmission filter if applicable.
  3. Clean the pan and magnet, removing any debris.
  4. Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically around 8-10 Nm).
  5. Refill the transmission with the appropriate type and amount of fluid (Porsche recommends their own PDK fluid).

3. Linkage Adjustment

• Sub-steps:
  1. Inspect the transmission linkage for wear and damage.
  2. If misaligned, adjust the linkage according to the service manual specifications.
  3. Test the linkage operation by moving through each gear.

4. TCM Reset

• Sub-steps:
  1. Reconnect the battery.
  2. Use the OBD-II scanner to reset the TCM.
  3. Clear any stored codes and recheck for new codes after a test drive.
