steep hill. put it in second from stand still and accelerate slowly if your can,until the clutch has been released then give it some.You want the clutch to be working hard. Soon tell if it’s the clutch.
Haven’t really thought about this too much so may be wrong but –
I guess most of the momentum required for a car to get rolling is at lower revs in first and second gear and therefore the engine and thus clutch would be working hardest at this point, which I think is consistent with your information given.
Please do not blame me if there’s are fiberous burning smell and you cannot get the mondeo back home.
