why does my Volvo XC60 First Generation (2008-2017) transmission slip when accelerating

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface, and the engine is turned off.
• Disconnect the battery to ensure safety.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
• Remove the transmission fluid drain plug and drain the old fluid into a suitable container.
• Replace the drain plug and torque to manufacturer specifications (usually around 20-30 Nm).
• Using a funnel, add the appropriate type and amount of new transmission fluid as specified in the owner’s manual.
• Check the fluid level again and adjust if necessary.

3. Inspect and Replace Transmission Filter (if applicable)

• Tools Required: Socket set, gasket scraper, torque wrench.
• Remove the transmission pan by unbolting it and carefully prying it off.
• Remove the old transmission filter and replace it with a new one.
• Clean the transmission pan and replace the gasket if necessary.
• Reinstall the pan and torque bolts to the specified value.

4. Test Transmission Solenoids

• Tools Required: Multimeter.
• Disconnect the electrical connectors from the solenoids.
• Set the multimeter to measure resistance and test each solenoid according to manufacturer specifications.
• Replace any faulty solenoids.

5. Reconnect Battery and Road Test

• Reconnect the battery.
• Start the engine and allow it to warm up.
• Conduct a road test to confirm that the slipping issue has been resolved.
