Red Line MT-85 is specially formulated to provide the perfect coefficient of friction for optimum synchronizer performance in manual transmissions and transaxles. This results in smoother shifting at high or low temperatures and enables higher speed downshifting. MT-85 is rated as a 75W85 gear lubricant and provides GL-4 gear protection.
We also offer Red Line MTL (Part No. 1693-MTL), which is rated as a 70W80 gear lube, and Red Line MT-90 (Part No. 3344), which is rated as a 75W90 gear lube.
