why does my Volkswagen Golf transmission jerk when shifting

Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

• Sub-steps:

  1. Locate the transmission dipstick or fill plug.
  2. Remove the dipstick, clean it, and reinsert it to check fluid level.
  3. If fluid is low, add the recommended transmission fluid (typically VW G 052 162 A2).
  4. If fluid is dirty or burnt, proceed to drain and replace it.

• Tools Required:

  • Funnel
  • Fluid catch container
  • Ratchet and socket set for drain plug

3. Inspect and Replace Transmission Filter

• Sub-steps:

  1. Remove the transmission pan using a socket set.
  2. Carefully detach the old filter from the valve body.
  3. Install the new transmission filter, ensuring it is securely attached.
  4. Clean the pan and replace the gasket before reattaching the pan.

• Tools Required:

  • Socket set
  • Torque wrench (check specifications for torque values)
  • Gasket scraper

4. Test and Reset the TCM

• Sub-steps:
  1. Reconnect the battery and start the engine.
  2. Use an OBD-II scanner to clear any transmission-related error codes.
  3. Drive the vehicle to allow the TCM to recalibrate its settings.
