2. Inspect and Replace Transmission Fluid

• If fluid is dirty or burnt, drain the transmission fluid using a fluid pump and replace it with new fluid.
• Replace the transmission filter if applicable.

3. Repair or Replace TCM

• If the TCM is faulty, locate it (typically mounted near the transmission).
• Disconnect the electrical connectors from the TCM.
• Remove the TCM mounting bolts using a socket set.
• Install the new TCM by reversing the removal steps; ensure all connectors are secure.

4. Reconnect Battery and Clear Codes

• Reconnect the battery terminals.
• Use the OBD-II scanner to clear the P0700 code from the system.

5. Test Drive

• Conduct a test drive under various conditions to ensure the transmission shifts smoothly and the check engine light does not reappear.
