Gear Oil for Manual Transmissions

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection

We invented the manual trans gear oil market with this, right, Al Gore?

MT-85 75W85 GL-4 Gear Oil

MT-90 75W90 GL-4 Gear Oil

The most popular, the most viscosity, the most applications.

D4 ATF

Versatile and stable. For both automatic and manual transmissions.

D6 ATF

As ATF requirements lean toward lighter viscosity, this one has ultimate stability.

The high-protection/low-drag formula in an intermediate viscosity.
