How do you change transmission oil in 2001 Mazda miata manual transmission?

To change the transmission oil in a 2001 Mazda Miata manual transmission, start by lifting the vehicle and securing it on jack stands. Remove the fill plug on the side of the transmission and the drain plug at the bottom, allowing the old oil to fully drain out. Replace the drain plug and refill the transmission with new oil through the fill hole until it starts to overflow. Finally, replace the fill plug and ensure everything is securely tightened before lowering the vehicle.
