Transaxle/Gearbox – Gear Oil
Redline MT-85 [ GL-4 Synthetic Gear Oil]
Editors note: The factory manual calls for hypoid gear oil [GL-5], this is incorrect. Additionally, the capacity should be 3 quarts/2.83 liters to give 5th gear added & needed lubrication. The GL-4 gear oil will not degrade the brass synchrinizers as the GL-5 will.
