1. Raise the vehicle and place it on stands.
2. Place a tray underneath, unscrew the drain plug and drain all the liquid, avoiding any losses. Replace the plug and tighten it.
3. Carefully remove the transmission oil pan and drain the remaining fluid. To remove the pan, unscrew the bolts and lightly tap the hammer to remove the seal.
4. Remove the bolts and filter from the transmission valve block (transmission filter bolts are indicated by arrows).
5. Check the condition of the fluid. If the fluid is dark and has a burnt smell, this indicates that the transmission is overheating.

In this case, it is recommended to take the car to a car service center.
