Overfilling M47 (or any) manual transmission can cause seals to fail?

Overfilled to something less than 2 litres, the reason is to keep oil in the top bearing of early M47's. I have never had a problem with leaking since I did it maybe 8 years ago.
To overfill you raise the left side of the car as high as you can get it on jack stands and fill the trans until the oil comes out of the fill hole. This probably only gets and extra 4 to 6 ounces of fluid in the trans but enough to keep the upper bearing in oil.
