my Skoda Octavia NFL (2020-Present) has a transmission fluid leak, what's the cause?

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine to cool before starting work.

2. Drain Transmission Fluid

• Tools Required: Socket set, drain pan
• Place a drain pan under the transmission pan.
• Remove the transmission pan bolts using the socket set.
• Carefully lower the pan and allow the fluid to drain completely.

3. Inspect and Replace Seals/Gaskets

• Tools Required: Scraper, clean rags
• Inspect the transmission pan gasket and any seals for damage.
• If damaged, remove the old gasket/seal using a scraper.
• Clean the mating surfaces on the transmission and pan thoroughly.
• Apply a new gasket or sealant as specified by the manufacturer.

4. Reinstall Transmission Pan

• Align the transmission pan with the bolt holes.
• Replace and hand-tighten the bolts in a crisscross pattern to ensure even pressure.
• Torque the bolts to the manufacturer's specifications (usually around 8-12 Nm, check the service manual for exact values).

5. Refill Transmission Fluid

• Parts Required: Manufacturer-approved transmission fluid
• Using a funnel, refill the transmission with the appropriate type of fluid as specified in the owner's manual.
• Start the engine and let it idle for a few minutes while shifting through the gears.
• Check the fluid level again and add more fluid if necessary.
