1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, multimeter, safety goggles.
• Ensure the vehicle is on a level surface and the parking brake is applied.
• Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Transmission Fluid

1. Remove the transmission dipstick and check fluid level.
2. If fluid is low, use a fluid pump to add the correct type of transmission fluid (consult the owner's manual for specifications).
3. If the fluid is discolored or smells burnt, proceed to replace the fluid.
4. To drain old fluid, remove the transmission pan using a socket set, ensuring to catch the fluid in a drain pan.
5. Replace the transmission filter if applicable.
6. Reinstall the pan with a new gasket and torque to specified values (typically 10-15 ft-lbs).
7. Refill with new transmission fluid through the dipstick tube.

3. Inspect Wiring and Connectors

1. Visually inspect wiring harnesses and connectors leading to the TCM.
2. Clean any corrosion found on connectors with electrical contact cleaner.
3. Repair or replace any damaged wiring as necessary.

4. Test and Reset Transmission Control Module

1. Reconnect the battery.
2. Use an OBD-II scanner to clear the P0700 code and any additional transmission codes.
3. Test drive the vehicle to monitor for any transmission issues or reoccurrence of the code.
