Another hint as I thought mine was leaking and went through the entire process of changing everything. Turned out there was no leak on the pan. Check closely at the shift shaft those seals are very common leak points and go out all the time especially when sitting for awhile as the fluid slowly raises up to that seal and migrates all over giving an illusion of leaky bolts and pan gasket.
Allison is so proud of the gasket they claim they are infinitely reusable and after changing mine I see why. This is on a 1000mh
