my Volvo XC90's transmission fluid is dark what should I do

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to ensure safety.

2. Drain the Old Transmission Fluid

• Locate the transmission fluid pan and place a drain pan underneath.
• Remove the transmission pan bolts with a socket wrench.
• Carefully lower the pan to allow the old fluid to drain completely.
• Inspect the pan for metal shavings or debris, which may indicate internal damage.

3. Replace Transmission Filter

• Remove the old transmission filter from the valve body.
• Clean the mounting surface on the valve body thoroughly.
• Install the new transmission filter, ensuring it is securely attached.

4. Reinstall Transmission Pan

• Clean the old gasket material from the transmission pan and mating surface.
• Place a new gasket on the transmission pan.
• Reinstall the pan and tighten the bolts to the manufacturer’s specified torque (typically around 8-10 Nm, but refer to the service manual for specifics).

5. Refill with New Transmission Fluid

• Use a funnel to refill the transmission with the recommended type of fluid (e.g., Volvo ATF fluid).
• Start the engine and cycle through the gears while checking the fluid level.
• Add fluid as necessary to reach the optimal level on the dipstick.
