Red Line MTL is GL-4 rated.
From their site:
MTL® Manual Transmission Lubricant
a 70W80 GL-4 gear oil (SAE 5W30/10W30 engine oil viscosity) designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.
Great stuff too. There is also a 90 weight MTL. I've run it since my first chnage. Shifts like a dream (Hot, Cold or Whenever). Just pay the $ more a quart and do it right.
Oh yea, You can get it in gallons so you don't have to screw around with 4 little bottles. Get yourself a funnel with a LONG hose end. It is the only way to get it to the fill plug.
