Hi All,

Car is a 05 TD42TI with 160,000kms with a full service history.

When I change gear at high RPMs (3k+, sometimes 2.5k, but rarely) there is a slight chatter noise and i can kind of feel a vibration in the pedal. Due to this, I've replaced the clutch with a UFI clutch, the spigot bush, and the throwout bearing. The flywheel was machined at the same time. The noise is still present, albeit not as loud, but it's still there. Driving around normally it's perfectly, sounds great and feels great. The noise/chatter is only there when I get on it, so higher revs. The clutch was replaced by the old man (mechanic of 30+ years) but the noise is still there. Before i just got throw money at a gearbox/driveline specialist, any ideas? The old man isn't too certain and is also at a bit of a loss. Is there a possibility that the master/slave cylinder is worn inside and causing a problem? Thinking maybe its the input shaft bearing? Which would suck, as we only had access to a hoist for a few days and ill also need to pay someone if its that! Any ideas? Thanks.

Thanks,
Mitchell
