Hi, I'm suffering some clutch slip on my 86 110 CSW but only after its battled along the motorway for 30 mins or so. After a couple of miles off the motorway it goes away and I can't replicate the fault when the engine is cold. Even with excessive revs when applying the brake the engine starts to stall as it should and everything appears normal. Is this just the first sign of the clutch starting to go, or is there something else that could be causing this?
Thanks
