Default Motul 75W-90 Too Thick?

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.
Thanks for your thoughts Jsolo.

Is your Redline MT85 fixed viscosity? I wonder because there ain't much difference between the Nissan (75W-85) Fluid (MTF) HQ Multi 75W-85 or API GL-4, Viscosity SAE 75W-85

and the Motul 75W-90. At least I wouldn't think so... I don't drive it much in the winter so maybe its not an issue for me.
