Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely supported with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the fluid level.
If fluid is low, add the correct type of ATF as specified in the owner’s manual.

3. Inspect Transmission Components

Fluid Condition: If the fluid is dark or has a burnt smell, a transmission flush may be needed.
Linkage Inspection: Remove the console cover to access the gear shift linkage. Inspect for wear or disconnection.
Electrical Connections: Check all connectors related to the transmission control module for corrosion or loose connections.

4. Replace Transmission Filter (if applicable)

Drain the transmission fluid into a pan.
Remove the transmission pan by unscrewing the bolts (use a torque wrench to avoid over-tightening).
Replace the transmission filter and gasket, ensuring proper alignment.
Reinstall the transmission pan and refill with new transmission fluid.

5. Reset Transmission Control Module

Reconnect the negative battery terminal.
Start the vehicle and allow it to idle for a few minutes.
Shift through all gears slowly to reset the transmission control module.
