2. Drain the Old Fluid

Lift the Vehicle: Use a hydraulic jack to raise the vehicle and secure it on jack stands.
Locate the Transmission Pan: Identify and locate the transmission pan under the vehicle.
Remove Drain Plug (if equipped): Use a socket wrench to remove the drain plug and allow old fluid to drain into the drain pan.
Remove Transmission Pan (if necessary): If there is no drain plug, remove the bolts securing the transmission pan and carefully lower it, allowing any remaining fluid to drain.
