Knowing you Mike, that comment has engineering merit to it! Care to explain? Pete

my S has transmission shunt (judder) if I try to be gentle with the throttle and clutch - much smoother if given more throttle

trying to reverse is terrible










wish I had not fitted a competition grade clutch

Can be a number of reasons, most will need the clutch off. However it can occasionally be caused by the clutch failing to release properly, if you are very lucky that might just be lack of clearance caused by the clutch rod not having any free play. It is an outside chance but it is at least worth checking that the clutch rod is slack when the clutch is engaged, and that the clutch lever is also free.

Incidentally, TVR didnt do a great job of converting from cable, the clutch rod isn't pressing the clutch lever at quite the right angle. It can also stick into the release arm as the end of the clutch rod gets worn. If it has been over adjusted to compensate it can stick.

My daily drive does the same under some combinations of torque and revs. You just get used to driving round it.

Seems counter intuitive to me somehow but contamination on the clutch can cause judder rather than slip, at least at first. If oil has leaked on to the clutch it can cause judder first. Not sure if it is easy to take the clutch cover plate (thin sheet steel plate on the bottom of the front of the bellhousing) off on yours to see if oil is leaking. If that plate is missing water and muck can get in and have the same effect.

(Many many years ago I have seen talc put into a clutch to help deal with contamination! Wouldn't want to risk it these days)

Select first, right foot down, left foot up and "drive like you stole it" for an hour or two



(possibly won't fix the problem but will take your mind off it)

Wasn't it Coca Cola that was the old remedy for overcoming clutch slip back in 'the old days'?
I never had to try it myself, but I had heard tales of it being used as a "get you back home" solution. Or for rallyists, to the end of the stage.
Anyone else heard of this Top Tip?

I must confess, I have used Coke in the past, not on a slippery clutch, but only to clean metal objects like old coins or artifacts, or to dilute Bacardi. :shuddernotjudder:

Thank heavens I discovered whisky just in time...

Never tried whisky on the clutch, always a first time, might smell nice when warmed up?

Yes I've seen coke being used a couple of times on rallies a long time ago

Guess this begs the question how or where do you put the Coke?


If you saw it years ago I presume it was "full fat" none of this Diet nonsense?


On our recent jolly around Scotland do you think Irn Bru would have worked?

[Spanish S2]

More revs, no judder!

must admit they were minis, and they have a very convenient inspection hole above the clutch/flywheel through which the sticky liquid could be poured. Presume on a Ford it would have to put in an pump action oil can and squirted from beneath the opening once the lower plate between the engine and g'box had been removed. Quite often left off as the area is protected by a sump guard.

Very early cars had clutches made from leather. Fullers earth was periodically pored into the clutch for better friction.

A flywheel that's had a slipping clutch on it for some time can become 'glazed', and if you fit a new clutch directly to it, you can get judder. That's why I normally have the flywheel refaced each time. Can't be dealing with juddery clutches!
