Clutch Slave Cylinder Failure???

A couple weeks ago, I noticed that it was getting difficult to shift into reverse. Over the last week and a half, shifting into second gear required more force (no grinding, just more muscle needed). Last weekend after driving the car for a couple hours, I parked the car and then smelled something burning, although I didn’t smell it again until last night. Last night, I left my house in the Viper (which was cold), shifted into first and then second two times on the way to a traffic light. When the light turned green, I shifted into first but then couldn’t get it to shift into second. Running out of momentum, I tried to shift back into first and couldn’t do that either. Again, no grinding—it just wouldn’t go into gear. I pulled over and turned the car off, put it into first and started it up. Again, when I tried to shift into second, it wouldn’t go, nor would it go back into first, requiring a repeat of the off-and-on procedure. While waiting for the light to turn green, in gear and with my foot on the clutch, I started to smell something burning that reminded me of the odor I smelled last weekend. Guessing that it was clutch related, I took my foot off the break, and the car started moving forward under its own power, despite the fact that I had the clutch fully depressed. Then while going down a steep hill in front of my house in first gear, and even though I wasn’t touching the clutch, break or throttle, the car twice changed speed, by briefly bogging down and going slower than it usually would in first gear going down this hill. I finally got the car in the garage and turned it off and notice for the first time that there is now almost an inch of play at the top of the clutch before it feels as if it’s engaging anything. What the…? Oh, and today the gears worked fine and even shift easily (that is for the 20 seconds it took me to maneuver out of the garage and behind the flatbed tow truck).

So now I’m guessing, after having a long and very helpful chat with JonB about the issue, that the pressure plate was not disengaging for whatever reason (faulty slave cylinder actuator, leaking hydraulic fluid?) and that, in addition to fixing the underlying problem, the flywheel has probably been glazed and now needs replacement too. Anyone else have any thoughts or problems like these?

So my 04 Viper, with a mere 1198 easy miles (1000 of which were break-in) on her, is in the shop for (i) this clutch issue, (ii) the cam sprocket bolts issue (yup, DC thinks my car was affected—I haven't had any symptoms…yet), and (iii) an ABS warning light that came on the other day (five minutes after I hit a *** hole) that will not go out. Other than ALL THAT, the car seems to be running just fine... Good grief. I've apparently fallen for a high maintenance girl. :crazy:

Help?

Re: Clutch Slave Cylinder Failure??? Rats!

An $85K American car at that. My 1998 V6 Camry, which I drive hard and barely look after, while not as much fun to drive as the Viper, has never let me down. Did I mention that when I had less than 300 miles on the Viper the triangular body panel just in front of the passenger door actually FELL OFF when I was washing it? There are three screws to hold this panel on—I heard the last of the three fall off right before the panel itself. One not-so-smart guy at the dealership said, “What do you expect? It’s a hand built car.”

Don't get me wrong--I love the car and will miss it while it's in the shop. Still, it's a little frustrating to have so many issues so early on.

Hang in there Russ,

Which dealership did you take your car to? Jason told me once that an ex-Woodhouse Viper Technician works at a Dodge dealership in Laurel (Laurel Dodge?). If your dealer is not able to do quality work on your car, then give Laurel Dodge a call. Good luck!

Soo.

Your symptoms that you described are exactly what happened to my 2001 Z06 to a tee. Every time I took it in, it would shift fine. Ended up trading it in before the issue was resolved.

Re: Clutch Slave Cylinder Failure??? Rats!

You know, assuming the flywheel will need to be replaced, I wonder if I can get the dealership, as part of the warranty work, to use the new Mopar lightweight flywheel listed in Viper Wizard's post earlier this year, assuming I pay any difference in price between the stock flywheel and the lighter flywheel.

Thanks for the encouragement, Soo. I'm hanging in there alright. I’m not too worried about the problems, given that I’m assuming they will all be completely fixed in short order. If it turns into a ongoing problem, as experienced by DonSchmeichel with his Z06, then I’ll get worried. I vote for bubbles and a good and fixable explanation as to how they got in there. Oh, and the car is at Jerry’s Dodge in Springfield being worked on by Jeff Sherman, all at Jason Heffner’s recommendation. I’ll let everyone know how things turn out.

Re: Clutch Slave Cylinder Failure??? Rats!

Sorry for the somewhat duplicate post, but for anyone not following the posts on the cam sprocket bolt issue or anyone doing a search on clutch issues in the future, I'm posting again here.

My Viper tech that's working on my car just called and said that the reason I had clutch failure is because two of the eight bolts holding the pressure plate together were backed out a quarter of an inch each and were apparently never tightened down during assembly. :rolleyes: My flywheel had some hot spots on it as a result and is being replaced, as well as the master and slave clutch cylinders just for good measure. All within the initial 1,200 miles.

Re: Clutch Slave Cylinder Failure??? Rats!

The torque specs for the pressure plate are usually very low, leaves very little room for error.

The hydro parts on the Viper are very sensitive also. Do you have a good pedal now, and is the engagment where you like it? I really don't like one to close to the floor when racing, but for normal driving it's great. Is your pedal stiffer or easier now? I've been thru some nightmares with pedal feel on the many Viper's I've had. Let us know how your's is working now.

Dang, I just saw this post!

SRT-10 trucks are experiencing a high incidence of slave 'failure'

I dont know if related, but Truck is is due to catalyst HEAT and proximity to the slave lines, boiling the clutch fluid.
Be sure any exhaust work has not affected the line routing. Upgrade fluid to DOT-4 or DOT 5.1 hie temp.

Thanks Jon. I'll have that checked as well. Get this, I learned yesterday of another 04 Viper that had clutch failure due to pressure plate bolts coming out. I'm betting this is going to be recall number 2 for the 04s.
