How do you change gearbox oil on Toyota MR2?

To change the gearbox oil on a Toyota MR2, first ensure the vehicle is safely lifted and secure. Remove the drain plug from the gearbox and allow the old oil to fully drain out. Once drained, replace the drain plug and then remove the fill plug; use a funnel to pour in the new gearbox oil until it reaches the appropriate level. Finally, replace the fill plug, and check for leaks before lowering the vehicle.
