75W90 trans fluid is too thick for Colorado. Probably fine if you live in FL or TX. Gears will be difficult to shift in the cold.

I ran redline MT85 for about a year and half (85xx miles). It was great initially but the following winter shifts were difficult until the trans warmed up. Difficult as in I could barely get it into 2nd. Did a trans fluid change back to nissan OE in the middle of january to fix. Perhaps because of the nature of the fluid (performance), the redline stuff just doesn't hold up as well. We'll see how the car does this winter.

With respect to clutch fluid, it's going to get replaced whether you want to or not during the master/slave replacement. Otherwise how else you going to bleed the line. Any decent DOT4 fluid is fine unless you're tracking the car.
