    Manual Transmission Fluids and their viscosities

    - is the lower bound value 9.8 cSt of the 75W-85 series a white paper value ? - is the viscosity curve (temp - cSt) linear ? - for cold weather replacement the value at 0°C would be much more interesting than at 100°C.

    Manual Transmission Fluids and their viscosities

    @molakule: yes, I'm experiencing cold weather shifting problems. The time span from starting the car til the oil is really warm. The problem exists only when shifting from 1st to 2nd and back. My concern is not wear or failure in the cold. My sorrow is that a 8.0 cSt oil is much too thin in...

    looking for a replacement fluid: temps outside now are about 0°C and in the middle of winter they will go down to -15°C. For my car MTF 75W-85 API Gl 4 is required according to the manual. No specific fluid (brand) is required. So I dont know the 100°C viscosity of the original factory fluid...

    Need help in understanding & correct choice of MTF

    OK , thanks Two more questions are rising up in this moment: - Why is 2nd gear shifting at higher rpms smoother than at lowers ? How can this be explained ? - One of my initial proposals of this thread was, to mix 70W80 with RL 75W90NS in order to improve friction value in cold and improve...
