Solution

1. Preparation

Gather all necessary tools and parts.
Safely lift the vehicle and secure it on jack stands.
Ensure the engine is off and the keys are removed from the ignition.

2. Check Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick and check fluid level; add appropriate ATF if low (consult owner's manual for specifications).
If fluid is dark or burnt, proceed to replace the fluid and filter.

3. Replace Transmission Fluid and Filter

Remove the transmission pan using a socket set; collect fluid in a drain pan.
Replace the transmission filter according to specifications.
Clean the pan and replace the gasket.
Reinstall the pan with a torque wrench, applying the correct torque (typically around 8-10 Nm).
Refill the transmission with new fluid as specified in the owner's manual.

4. Inspect and Replace Transmission Control Module (if needed)

Disconnect the battery to prevent electrical shorts.
Remove the TCM, usually found near the transmission.
Install the new or reprogrammed TCM, ensuring all connections are secure.
Reconnect the battery.

5. Test the System

Start the vehicle and allow it to warm up.
Check for any warning lights on the dashboard.
Attempt to engage the transmission into gear to verify functionality.
