my Skoda Octavia NFL (2020-Present) is leaking transmission fluid, what should I do?

Solution

1. Preparation

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

2. Locate the Leak

• Use a flashlight to identify the source of the fluid leak.
• Clean the area of any existing fluid to ensure proper inspection.

3. Repair or Replace Components

A. If the Transmission Pan is Damaged:

1. Remove the Transmission Pan:

   • Place a drain pan underneath to catch fluid.
   • Remove the bolts securing the pan using a socket set.
   • Carefully lower the pan and discard the old gasket.

2. Inspect and Clean:

   • Inspect the transmission pan for damage or warping.
   • Clean the mating surface on the transmission.

3. Install New Gasket and Pan:

   • Place a new gasket on the transmission pan.
   • Reattach the pan and torque the bolts to the specified value (typically around 10-12 Nm).

B. If Cooler Lines or Seals are Leaking:

1. Replace Damaged Lines:

   • Disconnect the lines using the appropriate wrenches.
   • Install new lines and ensure all fittings are secure.

2. Replace Seals or Gaskets:

   • Remove any old seals or gaskets from the affected area.
   • Apply a suitable sealant if required and install new seals.

4. Refill Transmission Fluid

• Use the correct transmission fluid as specified in the owner’s manual.
• Refill through the dipstick tube or fill plug until the correct level is reached.

5. Final Checks

• Reconnect the battery.
• Start the vehicle and allow it to reach operating temperature while checking for any additional leaks.
