Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid pump, fluid catch basin, new transmission fluid, new transmission filter, new gasket (if applicable).
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick to check fluid level.
2. If levels are low, add the correct type of transmission fluid (Mercon LV).
3. If fluid is discolored or burnt, proceed to drain the old fluid.
4. Place a fluid catch basin under the transmission pan.
5. Remove the transmission pan bolts and carefully lower the pan. Note any debris.
6. Replace the transmission filter and gasket.
7. Reinstall the transmission pan with new bolts, tightening to manufacturer specifications (typically 8-10 ft-lbs).
8. Refill the transmission with the correct amount of fluid through the dipstick tube.

3. Inspect and Repair Transmission Control Module (if needed)

Sub-steps:
1. Locate the TCM, usually found near the transmission or under the dashboard.
2. Disconnect the electrical connectors.
3. Inspect for any corrosion or damage to the connectors and wiring.
4. If the TCM is faulty, replace it with a new unit.
5. Reconnect the battery and ensure all connections are secure.
