Motul Gear 300 is GL-4/GL-5 rated, so fine to use in our transmissions and won't damage any yellow metals.

That said, I don't think it's any better than stock for cold shifts. I use it primarily for the shear protection at the track, but if I was doing a lot of daily driving, I'd probably try something else (like the Redline MT90 you mentioned).
