I may be in the wrong section, apologies if I am. About 2 weeks ago my car started making a funny noise at around 3000 rpm in each gear, it sounds as though the clutch is slipping and goes straight up to 3500k revs but still pulls. It's only done it twice and hasn't done it since, I've tested the clutch but it holds well and doesn't slip at all. Does anyone know what it could be or had the same issue ? Thanks.
