Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

• Remove the transmission dipstick and wipe it clean.
• Reinsert the dipstick and pull it out to check the fluid level.
• If low, add manufacturer-recommended transmission fluid (e.g., Mercon LV) until the correct level is reached.
• If the fluid appears burnt or contaminated, proceed to replace it.

3. Replace Transmission Fluid

• Place a drain pan under the transmission pan.
• Remove the transmission pan bolts using a socket set.
• Carefully lower the transmission pan and drain the old fluid.
• Replace the filter if applicable (remove and replace the filter as per manufacturer specifications).
• Clean the transmission pan, replace the gasket, and reinstall the pan using a torque wrench to the manufacturer's specified torque values.

4. Inspect and Repair Wiring

• Visually inspect the transmission harness and connectors for damage.
• Repair or replace any damaged wiring or connectors found during inspection.
• Ensure all connections are tight and free of corrosion.

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code and any additional codes retrieved earlier.
