Any spindle set with clutches such as a GM posi unit wont do so well with ATF.
The ring and pinion gears shouldn't really care what kind of oil they are in so long as they stay wet.
I think you could have problems if you put ATF in a differential used on applications other than light duty car stuff (I wouldn't mind being wrong on this).
It seems that on paper it should work but I have never found any one that has ever tried it.
Never try swapping ATF for gear oil in a manual transmission.

Thanks for confirming that ATF SHOULD be ok in an "open" differential (no clutch plates)
My friend who builds Diffs for a living has confirmed that ATF should work on in my differential- So I reckon it may be worth a shot- now to get the time to do it!
Its also common practise for us BMW folks to run ATF in the gearboxes here- makes cold shifting much easier- I have no Qualms about doing that-or I may try engine oil as a half way (Darin seems to suggest that the oil in the metro trans is similar to 5w30 engine oil..)
