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

Solution

1. Preparation

• Tools Required: Socket set, funnel, OBD-II scanner
• Raise the vehicle securely on jack stands and ensure it is level.
• Gather all necessary tools and replacement parts.

2. Check and Replace Transmission Fluid

1. Remove the transmission dipstick and check fluid level.
2. If low, add the correct type of transmission fluid (consult the owner’s manual for specifications).
3. If fluid is burnt or contaminated, drain the old fluid:
   • Place a drain pan under the transmission pan.
   • Remove the transmission pan bolts and carefully lower the pan.
   • Allow fluid to fully drain.
4. Clean the transmission pan and replace the transmission filter.
5. Reinstall the transmission pan using a new gasket and torque to manufacturer specifications.
6. Refill the transmission with fresh fluid using the funnel until the proper level is reached.

3. Inspect and Replace Components

1. If the slipping persists, inspect the throttle position sensor:
   • Disconnect the sensor and test using a multimeter.
   • Replace if out of specifications.
2. Test and replace any faulty solenoids if error codes indicate issues with shifting.
3. Consider checking for internal transmission wear; if needed, consult a professional for rebuild or replacement.
