Friend, them's fighting words. And yes, I know you were kidding.
I ran Dectron II for many years, probably many decades on account of the synchros bite way harder, than with EP oil. I only switched to 50% 85/90, or 85/115, whatever is handy, as I noticed the wear on the cluster pin. Straight ATF shifts like lightning.
But yes, if the ball-bearings are growly, the ATF will certainly let you know.
