Sounds to me like your transmission is going. Same **** was happening to mine before I realized that I blew some teeth off my differential gears. You might want to get it checked out before it gets worse

With that description, it could be a few things, but it's probably in the drive train. It doesn't really matter what people think it is or isn't, it only matters that you get it fixed. So either take it to a shop, or start trouble shooting.<p>Check for things rubbing, try to specifically locate the source of the sound while the car is on jackstands, etc.
