slipping clutch

1995 escort...while driving, engine revs but car goes no faster. Sounds like a slipping clutch? I had the clutch replaced less than 25,000 miles ago and the car is not abused. Any other suggestions.

It's a clutch problem, sorry dude :(

It could possibly be an oil leak which is spilling on to the clutch... but it all requires the clutch to come out again anyway.

MM22, can it be adjusted? I know on my pickup, I had the clutch contaminated, but rather than slip, it would grab something fierce or grab and release repeatedly really hard shaking the truck. Once engaged, I had no slippage, but I sure didn't like changing gears. Tore up a couple pinion yokes too. No fun.

There are no adjustments on this clutch. It is a simple hydraulic clutch.
No matter what the problem is, whether an actual clutch problem or some sort of leakage, the clutch is going to have to come out. Also, be sure the flywheel is resurfaced, is within specs, and is clean.

My own experience some years ago was with an oil leak from the rear main seal. Accelerating too fast would cause slipping. It sounds like this car is getting to a certain rpm where it just can't keep a grip anymore.

What would cause a clutch to slip sometimes, but not all the time?

On the backside of your cluctch pedal is a pushrod that is adjustable. This adjusts the freeplay. Your problem could be that you have no freeplay. My manual says the freeplay should be 1/4 to 1/2 an inch.

And how do you see if there is or isnt any free play? And if not, how do you adjust that? Would that maybe fix the problem with having to mash the clutch pedal to start it, or is that the neutral position sensor needing adjustment too?

ok, its got some freplay in it, but almost seems like it might be a bit excessive. Is there any way to adjust the neutral switch? I would prefer not to jam my clutch in every time I start my car. Otherwise to adjust the pedal, you have to adjust the pushrod lock nut?

If it has too much freeplay then that's NOT why your clutch is slipping.

The switch is adjustable but I think the picture may be wrong. I think on my car there are two switches. The one you need to adjust is closer to the firewall. You can see it if you can get your head down there :banghead:

Ok, So just loosen it and move it? Is it bad to have about and inch, to and inch and a half freeplay in the pedal? Im thinking the clutch needs to just be replaced, but im hopeing i wont have to many problems with it for a while.

I'd think it is OK as long as the car doesn't try to move with it in gear and clutch peda depredded.

Actually it does, I cant park in my friends driveway because it will roll back while in gear. So it would probably be a good idea to adjust? Ill be taking a look at it tomorow.

You have something that will require more than a pedal adjustment. These clutches shouldn't require any kind of adjustment. I've never had to adjust one. If something feels wrong it is usually related to low fluid.

Remove the inspection cover from the bottom of the tranny at the flywheel and have a look in there. You should be able to tell if there is a leak or if the clutch or flywheel is in bad shape.

You said you only have trouble when accelerating. If the car otherwise acts normally when cruising around at low speeds, then there is something wrong where the clutch meets the flywheel.

I can ussually only push on the gas maybe an inch more then where it is at before it will start to slip. It really doesnt matter what speed im going. As long as I am staping the same speed or accelerating slowly, im fine. The pedal has about an iinch to an inch and a half of free play. The master cylinder has plenty of fluid, even before I did my brakes the other day it had plenty. This has been going on for about a month, if not more. I will check that out this week if I can.

Well, your pedal does have too much free play. However, pressing the pedal DISENGAGES the clutch and doesn't have much of anything to do with a problem of slipping.
Are you able to change gears easily? If so, the clutch pedal is likely working just fine.
You likely have a worn clutch or you have a leak. The pedal should be the least of your worries right now.

Yeah, pushing in the clutch disengages it, but if you put it in part way, it will slip, which is normal. I wont be able to look at the flywheel and clutch and for a leak until probably sunday, so its gonna be a few days, unless I bring my other jack with me to my gf's. And gears do change fairly easy, reverse and first I some times do, first, starting from a stop, sometimes seems really tight, and reverse it just doesnt always like going in ear the first or second time when I pull it back, it will be in the right position, but it stays in neutral when pulled back.

Where on the net can I find instructions on how to change a clutch?

Where on the net can I find instructions on how to change a clutch?You can do a search for service manual pdf's for the car, but you will probably have to pay for most of them. Otherwise you can go to your local library and get a chiltons or haynes manual.

Wasnt the clutch for the most part, it was fairly worn, but still was ok. It was the flywheel that was causing it to slip really bad. Couldnt sustain it at more than 50 mph while in second gear and could put it in first and let off the clutch and it wouldnt stall while stoped and had to take it up to ove 5,000 rpms to even move it. So I took it to the shop last weekend and got it back the other night and he told me the flywheel was causing it for the most part. The fork plate was also worn down like ive never seen either.

What kind of condition was your flywheel in that would cause it to slip? What about the pressure plate surface? Could the pressure plate not be clamping the clutch enough? Or was there too much clutch disc wear or other wear or out of adjustment to cause the slippage?

If you got the flywheel turned replace the other parts. The parts are cheap compared to the labor.

Clutch disc had plenty of time left on it, the pressure plate was fairly worn down too, but the mechanic said it was due to the flywheel for the slipping, the clutch was feeling great since I got it fixxed, but the car has been decomisioned as of last friday, got a 1.8L motor for sale, brand new alt, water pump, timing belt, v-belt, serp belt, clutch thats just barely broke in, 230 k miles, runs great, $100 obo, ship from Sioux Falls, SD, pm for details

I was hoping to learn what kind of condition would the flywheel have to be, for the slipping to occur. Was it glazed, real smooth so the disc wouldn't grab? Conversely, too rough and your clutch wouldn't last a month.

After all of the repairs, why part it out? Tranny go? Too bad.

Depending on usage and how many times it may have been turned in the past, I suppose a flywheel can reach a point that it doesn't have the appropriate thickness for the clutch to grab it... same as rotors.
I haven't ever run into the problem of a flywheel being to worn, but I am sure it happens.

Motor and tranny are good, just wound up destroying the front end, rearened some lady when driving last friday, looked down for 2 seconds at most, looked up and slammed on my breaks and slid into her, probably at 20mph. I dont get it, most of my accidents are when I am driving good, like im supposed to. Still runs just cracked the radiator, mangeled up the mounts, hood, bumper, lights, drove it right up onto the trailer earlier tonight. Dont think im gonna get a chance to part it out. All i did was get the flywheel turned and put in the new clutch and it worked good.
