1.2 Change Fluid (if necessary):
- Drain the old transmission fluid by removing the transmission pan.
- Replace with manufacturer-recommended fluid, ensuring the correct type and quantity.
- Reinstall the pan and torque bolts to manufacturer specifications (typically around 10-15 ft-lbs).

3. Repair or Replace Faulty Components

2.1 Repair Wiring:
- Inspect and repair any damaged wiring or connectors found during the visual inspection.
2.2 Replace Solenoids (if necessary):
- Remove the transmission pan again to access solenoids.
- Unplug the electrical connectors and remove the retaining bolts.
- Replace with new solenoids and torque to specification.

4. Reset Transmission Control Module

3.1 Clear Codes:
- Use the OBD-II scanner to clear the P0700 code and any additional transmission codes.
3.2 Reconnect Battery:
- Reconnect the negative battery terminal and ensure all connections are secure.
