why is my Volkswagen Golf MK7 (2015-2019) transmission making noise in reverse

Solution

1. Preparation

• Ensure the vehicle is on a level surface and secure it with wheel chocks.
• Disconnect the battery to ensure safety during inspection.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, 8mm socket, funnel.
• Sub-steps:
  1. Remove the transmission fluid fill plug using an 8mm socket.
  2. Use a fluid pump to extract old transmission fluid if needed.
  3. Inspect the fluid condition; it should be a clear red color. If it is dark or has a burnt smell, replace it.
  4. Refill the transmission with the manufacturer-recommended fluid using a funnel until it reaches the proper level.

3. Inspect and Replace Transmission Mount (if damaged)

• Tools Required: Jack, jack stands, socket set.
• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Locate the transmission mount and inspect it for cracks or excessive wear.
  3. If damaged, remove the bolts securing the mount using a socket set.
  4. Install the new transmission mount and torque bolts to the manufacturer's specifications.

4. Inspect Drive Axles and CV Joints

• Tools Required: Jack, jack stands, socket set.
• Sub-steps:
  1. Lift the vehicle and secure it with jack stands.
  2. Visually inspect the drive axles and CV joints for any signs of damage or excessive play.
  3. If any components appear worn or damaged, remove and replace them using a socket set.

5. Reassemble and Test

• Sub-steps:
  1. Lower the vehicle and reconnect the battery.
  2. Start the vehicle and engage reverse to check if the noise persists.
