my Volkswagen Golf MK5 (2004-2008) transmission fluid is dark and burnt, should I change it?

Solution

1. Preparation

• Gather tools and parts needed for the fluid change.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine to cool before beginning work.

2. Drain Old Transmission Fluid

• Tools Required: Socket set, transmission fluid pump, drain pan.
• Place the drain pan under the transmission pan.
• Remove the transmission pan bolts using the socket set.
• Carefully lower the pan to drain the old fluid completely. Inspect the pan for metal shavings or debris.

3. Replace Transmission Filter

• Tools Required: Pliers, new transmission filter.
• Remove the old transmission filter (if applicable) using pliers.
• Install the new transmission filter securely, ensuring it is seated properly.

4. Clean and Reinstall Transmission Pan

• Tools Required: Gasket scraper, shop towels, new gasket.
• Clean the mating surface of the transmission and the pan using a gasket scraper.
• Place a new gasket on the transmission pan.
• Reinstall the transmission pan and torque the bolts to the manufacturer's specifications (typically around 10-12 Nm, but verify in your service manual).

5. Fill with New Transmission Fluid

• Tools Required: Funnel, new transmission fluid (check specifications for type).
• Using a funnel, fill the transmission with new fluid through the dipstick tube.
• Start the engine and allow it to run for a few minutes, then cycle through gears to circulate the fluid.
• Check the fluid level again and add more if necessary until it reaches the correct level.
