I bet you were surprised

anyway the problem I have got is a nasty rattle coming from the gear box end ,this all started last September its not got any louder or worse ...took it to mr clutch they said that's your dmf mate ok I said thanks ....took it to a friends brother in law who has his own garage and he,s an old school mechanic ,even he said its your dmf ...when the engine is idling its noisy ,I press the clutch pedal in it stops ...from what you said gary im wondering if its my gearbox .....as for the flywheels im am now confused
and yes the transit connect has got the same engine as my focus......wonder if that noise is the layshaft in the gearbox ???
