Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick (if applicable).
Wipe the dipstick clean, reinsert it, and remove it again to check the fluid level.
If the fluid is low, add the manufacturer-recommended transmission fluid.
If the fluid is dirty or burnt, proceed to a fluid change (see step 3).

3. Change Transmission Fluid

Tools Required: Socket set, fluid pump, transmission fluid.
Remove the transmission pan bolts and carefully lower the pan.
Drain the old transmission fluid into a suitable container.
Replace the transmission filter (if applicable).
Clean the transmission pan and replace the gasket as necessary.
Reinstall the pan with the correct torque specification (typically around 10-12 ft-lbs).
Fill the transmission with new fluid using the recommended type.

4. Inspect and Repair Wiring

Visually inspect the wiring harness and connectors leading to the TCM and transmission.
Repair or replace any damaged wiring or corroded connectors as needed.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals and ensure they are tight.
Use the OBD-II scanner to clear the P0700 code and any other transmission-related codes.

6. Test Drive

Take the vehicle for a test drive under various conditions to ensure normal operation and shifting.
