The Mk3 Toyota Supra W58 transmission drain and fill plugs are located on the bottom and side of the W58 transmission. Generally, the hex is worn out and rounded from years of being used and needs to be replaced. The drain plug has a built in magnet to help pull ferrous debris out of the gear oil. These are high-quality Toyota OEM parts and they fit the Mk3 non-turbo manual W58 transmission. Please use the drop down menu to select the option/s that you need.
