how to fix a transmission slipping issue in my Volkswagen Golf Eighth Generation (2020-present)

Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to ensure safety during the repair process.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Remove the transmission dipstick (if applicable) and check fluid level; top off if low.
  2. If the fluid is burnt or contaminated, drain the old fluid using a catch pan.
  3. Replace the transmission fluid with the manufacturer-recommended fluid (e.g., VW G 052 162 A2).
  4. Refill the transmission with new fluid through the dipstick tube or fill port as specified in the owner’s manual.

3. Inspect and Replace Transmission Filter

• Sub-steps:
  1. Remove the transmission pan bolts using a socket set and carefully lower the pan.
  2. Remove the old filter and replace it with a new filter compatible with the 2020 VW Golf.
  3. Clean the transmission pan and magnet of any debris or metal shavings.
  4. Reinstall the transmission pan using a new gasket; torque the bolts to the manufacturer's specifications.

4. Check and Replace Transmission Solenoids

• Sub-steps:
  1. Locate the transmission solenoids in the assembly (refer to service manual for location).
  2. Disconnect electrical connectors and unbolt the solenoids.
  3. Replace any faulty solenoids with new ones.
  4. Reconnect electrical connectors ensuring they are secure.

5. Reconnect Battery and Test Drive

• Sub-steps:
  1. Reconnect the battery terminals.
  2. Start the engine and allow it to warm up.
  3. Perform a test drive to ensure that the transmission shifts smoothly and does not slip.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Multimeter
• Catch pan
• Transmission fluid pump (if necessary)

Parts Required:

• VW-approved transmission fluid
