^^^I know that it occasionally snows there, but I do not know just how long it STAYS cold in that desert, and just how low the ambients even go.
IF it mainly stays above 40* F, even in the middle of winter there, you WILL BE just fine with the Gear 300, year 'round.
You know what Pennsytuckey winters are like, and I had that Motul in the transaxle for this last one (still do now), and it was only a little bit 'balky'/hesitant on the few below 15*F days we had.
Once warmed up, it IS like the proverbial "butter".
I just wanted to try the MTF-2 to see what it is like, and maybe free up a couple of fractions of power to the wheels.
