– Rags

Step 2: Safety First

– Park your car on a level surface and engage the parking brake.
– Allow the engine to cool down to avoid burns.
– Wear gloves to protect your hands from hot oil.

Step 3: Locate the Transmission Pan

– Refer to your owner’s manual or consult an online guide to find the transmission pan.
– It is typically a metal pan located beneath the transmission.

Step 4: Drain the Old Oil

– Place the drain pan under the transmission pan.
– Carefully loosen the drain plug using a wrench or ratchet. Be cautious as hot oil may rush out.
– Allow the oil to drain completely into the pan.

Step 5: Clean the Drain Plug and Pan

– Remove the drain plug and wipe it clean with a rag.
– Inspect the washer on the drain plug and replace it if necessary.
– Clean the bottom of the transmission pan using a rag and degreaser (if available).
