904 pan leak...need back up !! lol

X2 on the metal core gasket. Best gasket made by far.

There's generally no need for RTV but if you do use it make sure you use RTV that's ATF compatible. Not all is.

The others already mentioned some other possibilities, the o-ring on the fill tube and the shift shaft seal. Could also be the upper seal in the shift shaft that seals the kickdown linkage stem. Another possibility is the front cooler line leaking and running down onto the pan. Gotta clean the trans. up real good and sit under it with a light and watch all those things closely for something leaking.
