Ya, doesnt sound like the tranny is on its way out. Some wear and tear will cause more clank and thud, but it doesnt mean its about to push up daisies. Everyone here has offered some great advice on workarounds to ease the rough soundtrack your VX is playing, and its all very cheap. Go with the joint lubes and see how it goes from there. I lube my joints (on the VX damnit, on the VX!) with every oil change and you would be surprised at how proper juicing will smooth out some of the noise and roughness.
I wouldnt worry so much about the tranny unless you start hearing subtle grinding, getting slippage in gear shifts, or lags/no shifts. All of these things build up though, so you would see them coming.
