Ok so ive got an 89 lx w/ a 5 speed. Everytime i shift and the rpms drop more than 2 or 3 hundred, i hear a thud. It kind of sounds like a backfire but its not. I checked the driveshaft bolts and they're tight. So are the tranny mounts. I couldn't see anywhere under the car that looks like its getting hit, but i still hear the sound....

Any ideas?
