Install New Fluid:
- Replace the transmission pan with a new gasket.
- Refill the transmission with the manufacturer-recommended fluid (Volvo ATF fluid specification).
- Check fluid level with the dipstick while running the engine to ensure it is at the correct level.

3. Inspect Torque Converter

Remove Transmission Assembly (if necessary):
- If the issue persists, it may be necessary to remove the transmission from the vehicle to access the torque converter.
Check Torque Converter Operation:
- Inspect for wear or damage in the torque converter.
- If defective, replace the torque converter with a new unit.
Reinstall Transmission:
- Reinstall the transmission assembly, ensuring all connections are secure.

4. Electrical System Check

Inspect and Repair Wiring:
- If any damaged wiring was found, repair or replace as necessary.
Test Torque Converter Solenoid:
- Use a multimeter to check the solenoid resistance; replace if faulty.
