Premature bearing failure. Of course there are a host of other things that saw extra wear, but that is what would suffer the worst from not having oil for 40 miles. Unless you were driving a road course for those 40 miles, I wouldn't worry about the synchro's.

I really wouldn't worry about it too much. I did an axle on a buddy's car (about 180k(?)on it, I think) and when I pulled the drain bolt, no fluid came out. I told him about it and he just laughed and said he was going to put some fluid in; but never did. Ran it this way for another YEAR until he blew up the car. So I'm thinking you got some room for error.
