Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to prevent any electrical shorts.

2. Inspect Transmission Fluid

• Remove the transmission dipstick (if applicable) and check the fluid level.
• If the fluid is low, top it up with manufacturer-recommended transmission fluid.
• If the fluid is dirty or burnt, proceed to drain and replace the fluid.

3. Replace Transmission Fluid (if necessary)

• Place a drain pan under the transmission pan and remove the drain plug.
• Allow the old fluid to drain completely.
• Remove the transmission pan (if applicable) and clean the gasket surface.
• Replace the filter (if equipped) and install the new gasket.
• Reinstall the transmission pan and torque bolts to manufacturer specifications.
• Refill the transmission with fresh fluid through the dipstick tube.

4. Inspect and Repair Wiring/Connectors

• Visually inspect the wiring harness connected to the TCM for fraying or disconnections.
• Clean any corroded connectors using electrical contact cleaner and reconnect securely.
• Replace any damaged wiring or connectors as necessary.

5. Reconnect Battery and Clear Codes

• Reconnect the battery terminals.
• Use the OBD-II scanner to clear the P0700 code and any related codes.
• Start the engine and allow it to reach operating temperature.

6. Road Test

• Take the vehicle for a test drive, monitoring transmission performance.
• Check for any reoccurring codes using the OBD-II scanner post-test drive.
