Steven,

When running, the transmission fluid level is at about the level of the pan
flange. After sitting a while without the engine running, the torque
converter will drain about 1/2 of its contents back into the pan, raising
the fluid level above that less-than-perfect flange gasket. Parking on an
incline tilts the pan, putting that level still farther above the flange.
So, yes, the pan gasket can easily react as you've described. Check & set
the fluid level with the engine running, then don't worry about it until
your next pan R&R.
