Over revving question

[stentona]

Hi Guys,

Just a quick question.
Driving on the M4 today, I found my 2001 C70 revving at about 4000rpm. I was in 5th (of course!) and doing just over 70mph. It stayed like that for a good few miles and it didn't seem to have much more power than that. After getting in a traffic jam & then getting back onto a clear ish part of the road it revved about 2800 at 70mph, which is whatI've been normally used to. Any ideas what the problem might be? If any?

Cheers
Stentona

Wrong gear selected?

Slipping clutch? Wrong gear?

I was defo in 5th

If it's a slipping clutch is it worth taking to a garage straight away?

Unless you were spinning the wheels in 5th at 70 the only thing that could cause that would be the clutch slipping, providing you were deffo in 5th.

I'm a good driver but not that bloody good! :laugh

Once its started slipping (if it is that) it will only get exponentially worse.
You can nurse the car about or do clutchless gearchanges (but that will knacker your synchro rings unless you are very good at it) to get a bit more out of it.

Thanks Chris. Sods law ... I have a potential buyer as I'm getting an MG ZT-T ... now I'll have to get the clutch fixed first
