2. Wipe it clean, reinsert, and remove again to check the fluid level.
3. If low or contaminated, drain the transmission fluid using a fluid pump.
  - Tools Required: Drain pan, fluid pump.
4. Replace the fluid with the manufacturer's recommended transmission fluid (consult the owner’s manual for specifications).
  - Fluid Type: Volvo-approved automatic transmission fluid.
5. Reinsert the dipstick and check the fluid level again.

3. Inspect the Transmission Linkage

Sub-steps:
1. Remove the center console cover to access the transmission linkage.
  - Tools Required: Socket set, trim removal tools.
2. Visually inspect the linkage for wear, damage, or misalignment.
3. Adjust or replace any damaged components as necessary.
4. Reassemble the center console cover after inspection.

4. Test the Transmission Solenoids

Sub-steps:
1. Remove the transmission pan to access the solenoids (if applicable).
  - Tools Required: Socket set, torque wrench, transmission fluid pan gasket.
2. Disconnect the electrical connectors from the solenoids.
3. Use a multimeter to check the resistance of each solenoid according to manufacturer specifications.
4. Replace any faulty solenoids.
5. Reinstall the transmission pan with a new gasket and torque to specifications.
