• Disconnect the negative battery terminal to prevent electrical shorts.
• Raise the vehicle and secure it on jack stands if necessary.

2. Check and Replace Transmission Fluid

• Tools Required: Fluid pump, drain pan, socket set
• Inspect the transmission fluid level with the dipstick; if low, top off with the manufacturer-recommended fluid.
• If the fluid is dirty or burnt, drain the fluid using a drain pan.
• Replace with new transmission fluid, ensuring it meets Honda specifications.

3. Inspect and Repair Wiring/Connectors

• Tools Required: Multimeter, electrical tape, wire connectors
• Visually inspect wiring and connectors for any signs of wear or damage.
• Use a multimeter to check for continuity and proper voltage in the wiring harness connected to the TCM.
• Repair or replace damaged wires and connectors as needed.

4. Replace Transmission Control Module (if necessary)

• Tools Required: Socket set, torque wrench
• If diagnostics confirm a faulty TCM, remove the old module by unbolting it from its mount.
• Disconnect the wiring harness from the TCM.
• Install the new TCM by connecting the wiring harness and securing it with bolts to the specified torque.
• Reconnect the negative battery terminal.
