hmmm,  the transmission oil story sounds *thick* with confusion :)

 From Wikipedia:

"API viscosity ratings for gear oils are not directly comparable with  
those for motor oil, and they are thinner than the figures suggest.  
For example, many modern gearboxes use a 75W90 gear oil, which is  
actually of equivalent viscosity to a 10W40 motor oil."    http://
