Hmmm HELP! Knocking sounds! Any idears??

hello everyone!!

This is a head****! I got a 1999 2.5 v6 156 with about 80,000 on the clock .. there is a distinct knocking sound coming ( I think) from the gearbox!
From what I can tell so far, it only comes when there is more then 1 person in the car and when I get to 6th gear over 4,000 rpm!

After its gone over 6th gear, I can hear knocking sounds in every gear and the speed of the knocking intervals change depending on which gear im in! As soon as I press the clutch however the knocking goes!!

I can feel vibrations an drivers side and passangerside although not sure which one is stronger ...
Another thing, as soon as I stop and shut off the engine, the knocking goes ... or if people exit the car while running, I can drive off with no knocking sound whatsoever!! Weard intit!!

-The car is lowered ( although that shouldnt make a diff)

The garage couldnt find any fault on the exteriors!

If you have any ideas, suggestions or experience with this problem, I would be very thankful to hear it!!!
