Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety warning: Disconnect the battery before working on electrical systems.

2. Transmission Fluid Change

Drain Old Fluid
- Use a socket set to remove the transmission pan bolts.
- Carefully lower the pan and drain the old fluid into a suitable container.
- Clean the pan and magnet for any debris.
Replace Filter (if applicable)
- Remove the old transmission filter and replace it with a new one.
- Ensure proper seating of the new filter.
Reinstall Pan
- Apply a new gasket or sealant as per manufacturer specifications.
- Reattach the transmission pan using the bolts, tightening to the specified torque (check service manual for exact values).
Add New Fluid
- Use the recommended transmission fluid type and add it through the dipstick tube or designated fill port.
- Check the fluid level with the engine running and the transmission in park or neutral.

3. Inspect and Repair Transmission Control Module (TCM)

Check Connections
- Locate the TCM, usually found near the transmission.
- Inspect wiring and connectors for damage or corrosion.
- If damaged, repair or replace the connectors as needed.
Reprogram TCM (if necessary)
- Follow manufacturer-specific instructions to reprogram the TCM using a compatible diagnostic tool.
