Re: Where does your clutch engage on the pedal? High or low? ---
Usually it would be pretty obvious that there are issues though, its not something that just happens overnight ... right?
First thing to notice would be grinding gears easier? ---

Mine engages at about 1/2 to 5/8 of pedal travel from the floor. I believe it used to be higher until I changed the clutch fluid.

Re: Where does your clutch engage on the pedal? High or low? ---
I slipping clutch isn't engaging. You won't notice grinding. If your hydraulics are going, they won't fully disengage the clutch, so that's when you get grinding. You can test for slippage by driving about ten MPH, put it in 5th and floor it. If it builds rpm slowly, its ok. If it slips, it'll build rpm faster as though you're revving it with the clutch pedal half engaged.
The best thing to do is talk to Jim at Power Torque Systems it the ZF Doctor. |

Re: Where does your clutch engage on the pedal? High or low? ---
OK, well the last few times I drove the car I noticed it was hard to get it into reverse ... almost taking two hands.
It seems to be intermittant, but I have been missing 3rd ... almost like its locking me out or notchy to go into gear , taking more force than it used to. This is the kicker ... now my pedal seems to be engaging almost to the floor, like the complete opposite as before. I hear a slight click sound also when the pedal is let out about 1/2". There is no clutch smell, the fluid under the hood looks good, and there is no slipping under load in a high gear. I am thinking I have a clutch linkage adjustment necessary? Maybe a lock nut is loose? Thanks for your suggestions! ---

My 93 and 95 are both midway. My 2012 ZR1 is about the same as your Viper.

Is your clutch hydraulic fluid topped off and bled?, outside of the throw-out bearing fork, there isn't any mechanical geometry to it outside of the clutch disc thickness. I would bleed it. a bad clutch would still release and it should never be hard to select a gear.

Re: Where does your clutch engage on the pedal? High or low? ---
Not sure if its bled or not , but its topped off and clean looking.
It may have air in it ... the guy who owned it before me posted on here that his kid drove the car one night and came home with NO fluid in the reservoir. Not sure how he fixed it or what he ended up doing in that situation though. The thing that kills me is the car has driven fine for the past 2 years I have owned it ... its just this past month the clutch is acting funny. Thanks for pointing out a possible issue ---

Re: Where does your clutch engage on the pedal? High or low? ---
I read up on Bill's ZFDOC site , and I am starting to think I am having clutch hydraulic master issues.
He says " The preemptive dog teeth are most susceptible to damage when the clutch hydraulic system becomes degraded. The sensation of NOTCH SHIFTING is more prevalent when the sliding collar's preemptive dogteeth become worn or badly deformed. Advanced stages of preemptive dog tooth wear may result in GEAR ENGAGEMENT DIFFICULTY due to metal burrs restricting normal movement of the sliding collar. A healthy clutch hydraulic system should provide silk-smooth gear engagement. " I just hope I caught it in time before any kind of damage has happened. How many hours is a clutch replacement? How about the time for the clutch master cylinder replacement? As far as trying to bleed the system first, I have never done that before ... what is the process? THANKS!!! --- EDIT : I just emailed Jim at PowerTorque too ---

"Try to put it into reverse when it first gets started.
If you have difficulty getting into reverse there’s a very good chance that the clutch master cylinder is not at 100%." This was a good page too : " http://tech.corvettecentral.com/2007...1996-corvette/ " It says to replace the slave and master at the same time. Looks like that is where I will be starting ! ---
