Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench, transmission fluid, funnel, shop rags.
Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to ensure safety.

2. Address Transmission Fluid Issues

Check the transmission fluid level:
- Remove the transmission dipstick and wipe it clean.
- Reinsert the dipstick, remove it again, and check the fluid level.
- If low, add the appropriate type of transmission fluid (refer to the owner’s manual).
Inspect the condition of the fluid:
- If fluid is dark, burnt, or has a foul odor, consider a fluid change.
- To change the fluid, drain the old fluid using a drain pan, replace the transmission filter, and refill with new fluid.

3. Repair Electrical Connections

Inspect the wiring and connectors:
- Disconnect the TCM connector and visually inspect for corrosion or damage.
- Use a multimeter to check for continuity and proper voltage to the TCM.
- Repair or replace any damaged wiring or connectors as needed.

4. Clear Codes and Test

Reset the trouble codes:
- Use the OBD-II scanner to clear the P0700 and any associated codes.
Reconnect the battery and perform a road test:
- Monitor the transmission performance and check if the check engine light reappears.
