Morning Scott

Sounds like one or more fingers have snapped off the diaphragm. They spin around with the clutch assembly like socks in a washing machine, and occasionally slip onto the mechanism and jam it up. Hence it's fine one minute (just when you think it's ok to go for a drive) and not the next (Beep! Beep!)!!

My Tuscan was exactly the same, and the culprit was a single finger.

As for the dealer / mate thing; if you can get the bits (and good luck on that!!!) then it is just a clutch at the end of the day - so a bit of DIY may be ok.
The problem is that the slave cylinder may also be on the way out, or may not (mine was shagged!) - is your mate up to stripping / examining / changing that? Then because it's a hydraulic system, it'll need bleeding right through. And so on.

I would personally go the indy route (I did - Austec), as these sort of jobs can get on top of you if you only think you know what you're doing. Is the potential risk worth £400 to you?

Hope you get it sorted soon mate.

Hi Neill,

thanks for the reply, my worst thoughts confirmed (B*****S)

The guy has is own garage and full facilities so as you say it is just a clutch change, what I don't know is if the engine has to come out and whether that is normal practice for clutch replacement, my guy might not be up for the extra agro, I will get the quote from him and Austec and see how they add up...

thanks again for the response it always helps to here of people who have had the same experiences

If you do change the clutch yourself and have to do the slave(highly likely),
when you put it back together refit only the clutch and bellhousing first
then bleed the hydraulics before refitting the box
as this is the part of the job that is most likely to give you trouble,
keep a clutch aligning tool in while doing this to stop the plates from moving once it works!
an old first motion shaft works well from a ford type 9 box(sierra/capri etc)it allows you to turn the clutch plates while the pedal is depressed to ensure clearence which is paramount as it will wear again quickly if there is any drag.good luck.

Had simular problem but I had no warning, went to local shop for groceries jump back in car unable to select any gears. Lucky enough i was parked on a hill so just about managed to get car rolling on its own steam to select first gear and creep the 2 miles home.
Turn out to be thrust bearing had siezed up and bored its way through the finger followers. The dealer replaced the whole clutch assembly, slave cylinder, thrust bearing etc etc on my car.

Ouch that sounds expensive when you say thrust bearing and finger followers isn't that within the engine and not clutch? so did you have to have engine work as well as the clutch ? or is the thrust bearing an finger followers all part of the clutch, apologies I don't know much about these things ??

No its not covered by the engine warranty, thrust bearing and clutch fingers are all part of clutch assembly and the gearbox side of flywheel & no engine work needed, you would need a fairly catastrophic clutch failure to need engine work. If your going to need to replace your clutch make sure you replace slave cylinder as well saves time and money later.
My whole clutch assembly was sent back to factory for inspection, as this apparently this was only the second time they had seen this problem. Anyway to cut a long story short it cost me over £1700 to get fix.
Must give Gatwick TVR a BIG thumbs up thou, as I had car back within 24 hours of the car leaving me on the back of the flatbed. plus they managed to get the factory to refunded me the cost of parts.

cheers I will definatley get the slave cylinder replaced aswell then, like you say its not worth messing around, i wonder if there have been any mods to new clutch assemblies as it would seem this isn't such isolated incident.

Is there any news on your engine probs I saw your thread below ??

It is very concerning about our crotches. They are turning into consumables like brake pads. I wonder if the latest cars off the production line are still using this flawed design?

No news on engine front, I guess it did'nt get to the dealers till late friday.
Being its Le-Mans weekend I suspect that it won't get looked at till Monday anyway.

Opinion seems to be that early failures are probably down to instal/set up than the clutch unit itself. I guess AP Racing know a thing or two about making clutches.

Well good luck hope its not bad bad news, I will be interested to know what they find.

Rolex £1500 Fited Clutches as consumables would not be good, I dont know if there is any evidence of a flawed design. In some respects I give up trying to work out how these things fail so early on, hasn't the motor industry been building clutches, engines, electrics etc etc for 50 years....I don't get it. I am becoming resigned to the fact that this is just the way it is and I either put up or shut up..

Well I did read on a previous clutch thread here that the exact same clutch is used in the new Aston Martin DB93k9%*&?"@e7h or what ever its called, & they've had no problems that I've heard of.
I think the problem lies in the way TVR has designed the rest of the clutch assembly that opperates the clutch.

It seems to be that the travel isn't properly limited so that the slave continues pushing after the release point therefore stressing the actuation fingers. Mine is adjusted so that it only just releases at fully down so we'll see how long it lasts this time.
