how to check for transmission fluid leaks on my Volkswagen Golf MK7.5 (2020-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.
• Disconnect the battery (if applicable) for safety.

2. Inspect Transmission Pan and Seals

• Tools Required: Socket set, torque wrench
• Remove any underbody shields to access the transmission pan.
• Inspect the pan for cracks or damage.
• Check the gasket or seal around the transmission pan for any signs of wear or leakage.
• If damaged, proceed to replace the transmission pan gasket.

3. Examine Cooler Lines

• Tools Required: Wrench set
• Follow the transmission lines from the transmission to the cooler.
• Inspect for any signs of fluid leakage or corrosion.
• Tighten any loose connections to prevent leaks.
• Replace any damaged lines or connections as needed.

4. Check Fluid Level and Condition

• Tools Required: Clean rag, funnel (if adding fluid)
• Remove the transmission dipstick and wipe it clean.
• Reinsert the dipstick and remove it again to check the fluid level.
• If the fluid is low, add the appropriate transmission fluid as specified in the owner's manual.
• Inspect the fluid for discoloration or burnt smell, indicating potential issues.

5. Use UV Dye (if necessary)

• Tools Required: UV dye kit, UV light
• Add the UV dye to the transmission fluid through the dipstick tube.
• Allow the vehicle to run for a short period to circulate the dye.
• Use a UV light to scan for leaks, focusing on joints, seals, and the transmission case.
