1. Remove the transmission dipstick and check fluid level and condition.
2. If low or dirty, drain the transmission fluid using a fluid extractor or by removing the drain plug.
3. Replace with manufacturer-recommended transmission fluid (e.g., Honda ATF DW-1).
4. Reinsert the dipstick and check fluid level again.

3. Inspect and Replace Transmission Filter (if applicable)

Sub-steps:
1. Remove the transmission pan by loosening bolts with a socket set.
2. Carefully remove the old filter and replace it with a new one.
3. Clean the transmission pan and replace the gasket if necessary before reinstallation.

4. Repair or Replace Transmission Control Module (if necessary)

Sub-steps:
1. Disconnect the battery again.
2. Remove the transmission control module from its mount.
3. Inspect the module for corrosion or damage; replace if necessary.
4. Reinstall the new or repaired module and reconnect the battery.
