2002 civic transmission problems

Hello, My daughter just purchased an 02 Honda Civic with 110,000 miles,
4 cyl. and an auto transmission. The car has been running great until
yesterday when it would rev up between second and third gear. She had
me drive it this morning and it took about a second to shift from
second to third so I told her to take it easy till I checked around on
it. Checked the fluid and it is full and looks clean. She called about
two miles from the house and the transmission is now not doing
anything. No forward and no reverse. There were no strange noises or
grinding from the tranny it just quit pulling. Any ideas?
