AMSOIL Manual Transmission & Transaxle Gear Lube 75W-90 GL-4

This is the only oil we use in our gearbox! It shifts like butter. Mitsubishi recommends using ONLY GL-4 transmission oils in your gearbox because the additives in GL-5 oils will eat your brass synchros and your gears will start to grind when you shift.
Your gearbox oil capacity is 2.17 liters, so you will need 3 of these for an oil change.
