Don't quote me, but i think they say not to use synthetic fluid due to the clutches on the posi. I guess it causes it to slip

I know they tell you not to run synthetic fluid in built trannys either.

Any basic GM gear oil will be fine

The Truetracs don't have clutches, they are gear driven. The Eaton LSD's have springs and cluth packs and require a special additive to the gear oil to eliminate clutch chatter.
