That's the clutch, you should feel it in both 3rd and fourth, in 
fourth it's usually a few seconds after the shift if you are only 
lightly on the throttle.  if you're still accelerating (like 
entering the freeway) it won't lock up till you easy up on the 
throttle.

You can test by lightly pressing on the brake.  If the clutch is 
engaged it'll immediately disengage when the brake switch closes, and 
engage again a few seconds after you let up.  You can feel this, and 
hear the engine rpm change.
