Allow the vehicle to cool if it has been running.

2. Transmission Fluid Change

Drain Old Fluid
- Locate the transmission drain plug and place a drain pan underneath.
- Remove the drain plug and allow the fluid to drain completely.
- Inspect the old fluid for metal shavings or burning smell indicating internal damage.
Change Filter
- Remove the transmission pan by unscrewing the bolts.
- Carefully take off the pan and remove the old filter.
- Install a new filter ensuring the gasket is properly aligned.
Reinstall Transmission Pan
- Clean the mating surfaces of the pan and transmission housing.
- Place a new gasket on the pan or use gasket maker as appropriate.
- Reattach the pan using a torque wrench to the manufacturer's specified torque.
Refill with New Fluid
- Replace the drain plug and fill the transmission with the recommended fluid type using a funnel.
- Check the owner's manual for the correct fluid specifications and quantity.

3. Inspect and Replace Components

If diagnostic codes indicated issues with the TCM, replace or reprogram it as needed.
Replace any worn engine or transmission mounts detected during inspection.
If drive shafts or CV joints were found faulty, replace them to ensure smooth operation.
