Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid pump.
Safety Warnings: Disconnect the battery before beginning work on electrical systems.

2. Inspect and Replace Transmission Fluid

Raise the vehicle using a jack and secure it on jack stands.
Locate the transmission fluid drain plug and remove it using a socket wrench.
Allow the old transmission fluid to completely drain into a suitable container.
Inspect the transmission fluid for metal shavings or burnt smell; if found, further inspection of the transmission is necessary.
Reinstall the drain plug and torque it to the manufacturer’s specifications (check service manual for exact torque value).
Using a fluid pump, fill the transmission with new fluid according to the manufacturer’s specifications (check the service manual for the correct type and amount of fluid).

3. Check and Repair Electrical Connections

Locate the transmission control module (TCM) and inspect wiring harness and connectors for any damage or loose connections.
Clean any corrosion with electrical contact cleaner and ensure all connections are secure.
If any damaged wiring is found, repair or replace the wiring as necessary.

4. Clear Error Codes

Reconnect the battery.
Use the OBD-II scanner to clear the P0700 and any additional transmission-related trouble codes after performing repairs.
Test drive the vehicle to see if the check engine light returns.
