Would there be any adverse consequences from having a little extra fluid it the transaxle? I wasn't able to get the car completely level for my last change (only a few hundred miles ago) so I wound up draining it and putting in all 4 quarts of fluid, which came right up to the fill plug. But given the angle, I'm concerned that this is really a couple of millimeters above the max fill level. Given that this is more like a manual transmission than an automatic I can't think of a rational reason to be concerned. But I don't know everything. Thoughts?
