yeah when i replaced the clutch the i asked the guy at auto zone what kind of oil i needed and the guy said "normally i use 75-80w"on my car so i took couple of those and i poured them into the tranny only to find out a couple of weeks later that it uses gl4 or gl5 gear oil the guy drives a vw not a mitsubishi so i drained the tranny and filled it with gl5 ran it and didnt feel right so i went with gl4
