well while driving my car on trip to the beach all of a sudden it just popped out of gear. so i put it back in gear shortly there after it popped back out. well that whole weekend and since then i have been having the trouble. it varies in the time it takes for it to occur. well when i got home i checked the fluid it was a little low, so i filled it up and still having trouble. the only thing i think that could cause the trouble is that about a week before the trip my g/f was driving while i was drinking and she went over a speed bump just a bit to fast and knocked the exhaust loose. well i rehung before i left out of town. so do you think it could be the synchro's, 5th gear is going, or the shift linkage is out of whack? but there is nothing grinding when i go into 5th or anything.... thanks for the help!
