Rich,
Your scinicizm is appreciated, howvever gear oil does contain the sulfer,
(its what you smell in the gear oil). Gear boxes do not generaly get hot
enough to cause the reaction(~175 C). Gear oil does need to be changed
periodically for this reason.
An old alpine transmision wizard once told me the reason that most english
cars use engine oil in the transmisions was because the gear clearances were
tighter than in american cars, also the EP additives in the gear oil gets
sheared by the closer running gears.
