Why Not Mobil 1 V-Twin 20W-50 in Tranny?

I run M1vtwin in the trans...I put in gear oil once and I didn't like the way it shifted..it felt kind of sluggish going from gear to gear (but it was quieter on the high way)...I figure it is partly because it only had 4000 miles on it when I put in the gear oil, and as it gets more miles on it I may go back to gear oil...

yes they fixed it,they went to a weeker sphryical cut gear vs the stronger streight cut gear.spectro gear lube in the gear box (although any good gearlube is fine with me) motor oil in the motor(dont want v-twinn in my motor).primary gets v-twinn(lack of friction modifiers make it safe for clutch but bad for motor).

I've been in the heavy duty truck parts business for 31 years. About 25 years ago Eaton started specifying straight 50 wt oil for their transmissions. These trucks are driven by everything from good, experienced drivers, to some of the worst cowboys you ever saw. Lots of them go over a million miles, pulling 80,000 lbs. These 13, 15 and 18 speed transmissions have way more moving parts than a motorcycle transmission.
I know a few old men who won't use what Eaton recommends, because their grandpappy told them they had to use a heavier weight oil in a gearbox. They think they know more about it than the engineers who have done extensive testing and determined that 50 wt. is the ideal oil to use. I don't think they do.
