Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Check the fluid level; if low, add the recommended transmission fluid (typically Mercon LV for this model).
3. If fluid is burnt or contaminated, drain the transmission fluid using a fluid pump.
4. Replace with new transmission fluid until the proper level is reached.

3. Inspect and Repair Transmission Control Module (TCM)

Sub-steps:
1. Locate the TCM, usually found near the transmission or under the dashboard.
2. Disconnect the electrical connector from the TCM.
3. Inspect the connector for corrosion or damage; clean or replace as necessary.
4. Reconnect the TCM and secure it back into place.

4. Test Drive and Reset Codes

Sub-steps:
1. Reconnect the vehicle battery.
2. Start the engine and allow it to reach operating temperature.
3. Take the vehicle for a test drive to monitor shifting behavior.
4. Use the OBD-II scanner to clear any stored codes and verify that no new codes appear.
