got my first scooby (turbo 2000 1994) a couple of months ago and ever since have had it the gears make like a wineing noise its fine going up the gears but when am comming down say up to traffic lights there is like a wineing noise anybody no what this could be i dont think it could be the clutch cause its fine going up gears

 

could be that it wines but you dont hear it when the engine is revving up?

The scoob boxes have to be strong so some whine is to be expected i guess?
