Gear Box Oil

Hi All
I have read many posts on the type of oils & grades that many owners use in their Gearboxes
I'm practically interested with owners who use ATF
Do you have any long term data on how the oil is performing and more important if there are any detrimental issues associated with using it??

Thank you

WOOOOOHOOOOOO!!!

OIL THREAD!!

Well the last oil thread certainly was a huge step forward...
