Solution

1. Preparation

• Gather tools and parts required for the repair.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Tools Required: Socket set, funnel, drain pan
• Remove the transmission drain plug using a socket wrench.
• Allow the old transmission fluid to drain completely into the pan.
• Replace the drain plug and torque it to manufacturer specifications (consult repair manual for specific torque value).
• Fill the transmission with new fluid through the dipstick tube using a funnel, ensuring to use the specified fluid type (Honda ATF DW-1).
• Start the engine and let it warm up; check for leaks and verify fluid level.

3. Repair or Replace Faulty Components

• If any specific trouble codes were identified during diagnostics:
  • Wiring Harness: Inspect for damage or corrosion, repair or replace as necessary.
  • Transmission Control Module (TCM): If faulty, remove and replace with a new TCM, ensuring to follow the manufacturer's programming procedures.
  • Throttle Position Sensor: If faulty, disconnect its connector, remove the sensor, and install a new one, ensuring proper alignment.

4. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use an OBD-II scanner to clear trouble codes from the vehicle's computer.
