Road speed is from the ABS sensors I think Fatz

Also, fuked clutch or not, if you push down on the accelerator you expect to see a rise in RPM don't you?

Ive heard it was from the front ABS sensors, but I disproved that by hitting 110km on my speedo spinning in the wet while the car was stationary, hence why I am not 100% certain where it is measured from, I could find out very shortly though

You do expect to see a rise in RPM, but initially it wont flare as much as others have suggested it will. You will only see a 500-1000rpm increase as the clutch will still oppose some friction onto the flywheel

I didnt say a slipping clutch would result in the revs goin of the dial. Say if your in 4th sitting at 80-90kmh then sink your foot into the throttle the revs will raise up around 1000 revs and the speedo might go up only 10-20kmh. I made a post about this happening ages ago and just got told I couldnt drive but I got a replacement clutch out of it

What you describe here is symptoms of a slipping clutch, if you made a post about it and you were told that you could not drive, the people who posted that should refer to my above comment

Yeah I think they were auto drivers anyway fatz

Nothing wrong with auto drivers

I'm now driving an auto, dam manual T just kept getting owned of the line :blushing:

Its measured from your rear wheel abs sensor...

Sweet I couldn't be arse looking it up in the factory manual.

To many pages when you got a migrane

Cheers for the responses guy's, Fatz, you make a lot of sense with your theory, I too was expecting a greater rise in rev's, but of course it's not dead yet so it would only slip a little. I will give your experiment a try on the weekend and see how we go, I then might need to speak to our mate Mal.

I'm guessing none of you guys have actually had experience driving a manual or one that has a slipping clutch?

When a clutch is initially on its way out, it will NOT continue to free rev till it bounces of the limiter, but will more than most likely pick up 500-1000rpm and sit there until the cars speed equals the rev co-efficient as described above. The clutch still has some sort of opposing friction on the flywheel so thus a complete free rev will not happen initially. It will happen in the higher gears and then slowly work its way down to replicating the problem in the lower gears, why? Because giving the car WOT in the higher gears puts more initial load on the clutch and makes it way more prone to slipping. The fact that you say the car isn't pulling like it should makes sense because it isn't . The clutch isn't transmitting all that power to the rear wheels hence causing that sensation.

Quick test, go out put your car in a higher gear e.g 4th, sit on the point of the rev range just before you get a huge shot of power, depending on your tuner, it will most likely be about 2500-2800 odd rpm and give it WOT, at this point in time you should be able to experience what you have described above. Watch your speedo and your tacho, compare both and you will notice that the tacho should move a lot quicker than the speedo and when you back of the juice, the tacho will fall quite a few hundred rpm but the speedo wont fall much at all. This occurs because the engine speed (rpm) is derived, wait for it, at the engine, and the road speed (km) is derived at the wheels. Most cars have road speed derived from the gear box, but from my understanding that Ford might have added a sensor further down the drive train to get the road speed.

So in short if your experiencing what I have described above, your clutch has a limited life so don't give it a hard time until you can afford a decent unit.

Bloody ell ... Fat-Tony is right on the money with this one.

Tabbitha ... just shuddup! What would you know about a clutch anyhow? For you it's only about how to grip your beer.

teeq> Go do the test suggested .... sit in your car in your driveway, no better go out onto the street, select fourth gear and give it a bootful of revs and then drop your clutch. If the car stalls the clutch is good. If the engine slowly dies in revs then it is your clutch slipping.

If it's slipping it will quickly deteriorate if you keep provoking it with WOT at low revs in the higher gears. Go easy until you can get it fixed 'cos once it's gone it's gone and you'll be driving nowhere.

Fat Tony and Turbo06man are both right on the money...

First time for everything I guess

Having had a couple of clutches go in the T and Phoon I have a little recent experience.

What the fat man said sounds about right to me.

In the early stages the clutch will "flare" at peak torque, particularly in a higher gear and up hill. It will be almost unnoticeable at first. A momentary increase in RPM without a corresponding increase in road speed. This will get worse as the clutches ability to hold lessens over time and wih each slip.

I'd be starting a search for a new one. Mal Wood would be a good place to start.
