Subject: Gear oil vs motor oil in manual trans

I recently had clutch work done. The transmission wasn't opened but was removed to get at the clutch. Before taking the car in, the clutch was growling and a light vibration could be felt through the clutch pedal. Other than that the car drove fine (no slipping, clanking, etc). They replaced the throwout (?) bearing, but the growling noise remained.

I brought the car to the dealer because the trans was still (barely) under warranty. They are going to void the warranty because they claim the other shop put gear oil back in the trans instead of motor oil and that considerable damage occurred.

I have two questions:

1) Why is the car still very drivable if, as they say, considerable damage has occurred? Other than the growling no other symptoms exist; the car was no worse after the clutch work than before.
2) I only drove the car maybe 80 miles between the clutch work and taking it to the dealer. Could 'considerable damage' have occurred in such a short period of time?

Thanks in advance for any advice.
