This is a discussion on clutch within the Transmission & AWD forums, part of the Tech & Modifying & General Repairs category; is there any harm in driving with a clutch until it dies(other than ending up with no clutch obviously)?...

    Most people will replace the clutch once it starts to slip really badly, as the car is not as drivable. Not too sure what you are really asking, but most people don't replace their clutch until it "dies," which might mean different things to different people. Of course, if you are planning an extremely high power build you might put a stronger clutch in there before the stock clutch goes. If you wait too long though, you might find yourself stranded.

    What is going on with your clutch? Is it slipping, or is the engagement point changing dramatically? If it is the engagement point, it could just be that your clutch fluid is low...If it is slipping, then different story. One way to tell is to put your car in 5th gear (while going maybe 25-30MPH), and then floor the pedal. If the car doesn't accelerate smoothly, then your clutch is slipping. (another common symptom is if you are in say 3rd gear, downshift to 2nd, and let out the clutch slowly...if the rpms don't go up immediately, the clutch is going).

    I would say the most harm is that it's dangerous. If your clutch is slipping badly you have greatly increased risk of being struck by an on comming car when you attempt to pull into the roadway and your car will no longer move.

    Drove mine till i could go thru all 5 gears without moving. Only downside is cleaning the nasty, black, burned clutch material out the bell housing.

    Drive until it starts to slip. Then get parts and replace. There is no use in driving until it just won't go anymore, you'll get only a very few (maybe no more than 100) extra miles out of it. Also ALWAYS replace throw-out bearing while at it. For testing slip, I'd recommend a speed where the engine runs about 3.5 - 4 K RpM, in the highest gear possible, then hit the gas. If it holds the clutch is good. If you do this at 2k you may not have slippage due to the torque not being there... Then it really doesn't tell you anything.
    You can't have everything - where would you put it?

    The clutch in my daily driver first started to slip some time in early 2009. I've been driving the car routinely ever since.

    It's not only saved me lots of money but also taught me valuable skills -- Jackie Stewart said "light is right" I think. Light on the controls, think ahead, etc.

    Granted, I've only driven the car with a slipping clutch for four years so I don't know how much longer it'll last, and at some point the car may become immobile. So far, so good though.

    Spiro, if you don't mind me asking: at what mileage did the clutch on your car start slipping?

    This is on a Toyota, to be clear. The first clutch started slipping around 140,000 miles and I replaced it at around 160,000 miles. The second clutch, the one still in the car, started slipping around 250,000 miles and the car now has 280,000 miles.

    The clutch in my Subaru does not slip. However, the dealer replaced my clutch assembly and flywheel at my request under warranty at 30,000 miles, so the "new" clutch only has 110,000 miles on it. I'll be disappointed if the Subaru clutch starts slipping before it gets to, say, 150,000 miles. Although it's common to think of turbo cars as a demanding application, there is little torque out of high boost so most of the rpm range in most gears and in my case most of the time is under low torque. In that sense I'd expect more life out of a WRX clutch than a RS clutch.

    ^ What torque load are you putting on the Toyota clutch (i.e. what torque does that engine have left ;-) ?
    And I don't mean that negatively, not'in wrong with making a clutch last, I hope I can get a decent life span out of mine.

    I'd think the WRX is meant to GO, and a slipping clutch wouldn't be very helpful there...

    I agree.

    I'm still on the OEM clutch at 108k miles of vehicle life (68k miles of ownership), though my transmission must endure about 1.8x the stock horsepower and 100 ft-lbs over stock. The clutch has yet to slip.

    Well, that's a valid question. Of the original 195 Nm specified when new, the car now produces roughly 0. This really helps clutch longevity.

    What year is your car?

    On the 06-07 model years, it was more common for the pressure plate to give out, leaving you with "light switch" engagement. Sure you could make it slip in higher gears when at stage 2 under load when the clutch had little mileage on it, but more commonly your engagement zone went to 0, making it very hard to drive.

    When that happened I replaced mine.

    I mean it was either engaged or disengaged. When letting the clutch out to get moving there was no friction zone. There's a DIY with pics in my sig line.
