6. Reinstall the pan with a new gasket, torque bolts to specifications.
7. Refill with new transmission fluid through the dipstick tube.

3. Solenoid Replacement

If solenoids are faulty:
1. Remove the transmission pan as described above.
2. Disconnect the electrical connectors for the solenoids.
3. Unbolt and remove the faulty solenoid.
4. Install the new solenoid, torque to specifications, and reconnect wiring.

4. TCM Reprogramming or Replacement

If the TCM is faulty, consult a Volvo dealer or a qualified technician to reprogram or replace the unit. This may involve software updates or hardware replacement.

Final Steps

Test Drive Again: After repairs, perform another test drive and monitor the transmission operation.
Monitor for Leaks: After repairs, check for any new leaks.
