5. Replace the transmission filter by removing the retaining bolts and installing a new filter.
6. Clean the transmission pan and replace the gasket.
7. Reinstall the pan and tighten the bolts to the manufacturer's specified torque (consult service manual for torque specs).
8. Fill the transmission with the appropriate type and amount of new fluid (consult owner’s manual for specifications).

3. Inspect Wiring and Connectors

Sub-steps:
1. Visually inspect all wiring and connectors leading to the transmission for wear or damage.
2. Clean any corroded terminals using electrical contact cleaner.
3. Reattach any loose connections and ensure a secure fit.

4. Reprogram/Update Control Module

Sub-steps:
