Discussion
Slightly strange problem this weekend - car booked in for Tuesday to investigate but interested to see if anyone else has had this issue or any ideas
Manual box, V12 engine - when I change up a gear, particularly in the higher gears, the revs go up very approx 1k revs and stay there for a few secs before dropping back down. It's almost as you would expect to see the rev counter behave when you put your foot on the gas in an automatic car, where the revs shoot up at first but then back down as the box changes gear, however in this instance of course I have a manual car
The characteristic can also be seen if you are in a high gear, at low revs and put your foot down on the gas. The revs go up sharply, then drop back down and then slowly start to rise again
I thought it might be clutch related, the garage over the phone have suggested a possible sticky throttle although I'm not so sure either is the issue. Thoughts ?

Thanks for the quick responses
Clutch was my automatic assumption, servicing department seemed to think not as I described it over the phone - sounds like I was right first time
Any experiences of cost to replace clutch in V12V or expected life (I've done about 19k miles in my car, from new)
Think I'm right in saying that those who have had clutch upgrades of one description or another have had them on the gearboxes fitted to V8 Astons, with no actual 'upgrade' options to the V12 car systems ? If there were one available, now seems the obvious time for me.

AML kindly fitted a new clutch to my V12V at about 5000 miles since the old one had a defect that was detected by a professional (I hadn't noticed, but I drive like Miss Daisy).
At that time (late 2012) AML quoted £4000 for supply and fit. That was negotiable.
If I needed a new V12V clutch now I would talk to BR, their clutch is twin plate like the AML V12V but will come with a lighter flywheel if you want that. They will also fit the right bearing right from the start!

I had a defective part which was replaced on a number of cars belonging to other V12V owners on here and I had to fight the dealer for weeks to get a resolution that was acceptable. In the end AML paid 100% of the cost but it was a faff and the dealer was not helpful.
It was not the supplying dealer but it was one that a number of folks on here rave about. No naming and shaming rules mean I cannot say it was dealer XXXX.
I don't have a BR clutch so I don't know what they would charge. I would guess it would be a bit lower than AML but with better quality components. I did consider the BR clutch and as I understand it (memory may fade) it was the same quality friction material as used in 1-77, so it's good kit.
So a brief update. Thanks for all the input and to Mike at BR for some advice over the phone. Car is due to be collected tomorrow by Stratstones - I assume they will concur it is indeed a replacement clutch that is necessary
The question of whether it will be covered under warranty is interesting. I agree with both points of view above to an extent - just because something is 'consumable' in the sense that you expect to have to replace every so often as a result of wear and tear does not mean it can't also be considered a warranty item, if it goes far earlier than expected
For instance, if brake pads/discs/tyres went after 1k miles, unless you had been treating the car like Chris Harris in a hooning video, you would have every right to say it was unreasonable. Clutch after 5k miles is patently unreasonable. Clutch after 35k miles if you expect 45-50k mile life is probably reasonable. Where inbetween do you draw the line i.e. is 19k miles reasonable for a clutch to be replaced under warranty ?
Let's wait and see what tomorrow brings.......

Unlike some specialists they don't quote prices online.The BR 'option' involves a lighter flywheel and a slightly more wear resistant plate (hope I've got the terminology more or less correct there - I can't pretend this is an area I'm overly knowledgeable in) however the difference between the AM standard fit equipment and the BR option is significantly less than the upgrade should you have this fitted to any V8 or an early V12V
The upshot being that unless you need to change the clutch anyway, there is no point going for the BR option. So, if the factory pay or if the dealer is able to get a significant contribution, it will by definition be much cheaper to stay with the dealer/factory fit option however if the factory refuse to contribute, I may as well go to BR on the basis it will be both cheaper and a little better

Does sound like clutch, high gear low rev and floor it is a classic test for slipping clutch.Clutch was my automatic assumption, servicing department seemed to think not as I described it over the phone - sounds like I was right first time

I looked at a Morning Frost V12VR manual that had an invoice in the folder for £3.8k for a clutch replacement
Dealer has confirmed it needs a new clutch just from a brief drive of the car
Initial quote................£4,900 including VAT !!!
They don/t recall having to ever do one on a V12V (which tells it's own story about mine going now) and it's 'in the book' as a 15 hour labour job, which requires the manifolds on one side being taken out......sounds somewhat OTT to me, to put it mildly
Next step is they have asked the factory to support a warranty claim - will be interesting to say the least to see how this one pans out
