Exclamation Clutch stuck engaged...

What is wrong? I think it is the friction plate stuck to the flywheel. Clutch pedal feels normal. Any ideas? It is a Spec 3+ with thier flywheel. Happened durring the burnout. Pretty sure the guy did not put me deep enough into the water box. Tires did not spin and the car lurched and died with heavy clutch slippage (had the line-lock on).

Well I vacuum bled the hydraulics and the fluid was clear. There was some air, but it did not change anything. Looks like the trans has to come out.

yep, you welded the flywheel to the pressure plate. I did this with my last 3+, it got hot on the launch and stuck together.

What clutch to you run now? Did Spec do anything for you? This is stupid. A clutch should be designed to not do that.

I've seen a couple of clutches "welded" to the flywheel. We actually have got the un stuck by driving the car lol. Just hold the clutch pedal to the floor which will keep the pp in the released position. The go out and drive it...changing gears by rev matching. Once you get it into the higher gears like 5th or 6th just stab the throttle wide open from a low rpm and I bet the disk will come un stuck...just keep the clutch pedal to the floor during the whole process.

My old man done this on a customers car once and taught us all a lesson. Since then we've done it one other time and it worked then too...in both cases the clutch keep working fine afterwards.

When the clutch pedal is pressed in and the trans in gear, the car will be in gear. So when you start it in gear, the car rolls.

Jon, I tried driving it in the pits and it did not give, but that was like 10mph and in 1st. I will see if I can try higher speeds and gears. I also put the rear in the air and tried working the e-brake while in 3rd. Prolly not enough inertia. Wouldn't a lower gear work better? More torque?

A higher gear will be more likely to break it free. For example, when a clutch begins to wear out, it will show signs of slippage in the higher gears first. The engine is going to make the same amount of torque regardless of what gear its in. Ever tried to do a burnout starting of in 5th gear? Probably not, right...but if you did you'd probably slip the clutch not the tires. The lower gears have more torque multiplication which would move the car easier and put less stress on the clutch itself.

You should be able to take of in 2nd gear and work your way up to 5th or 6th as long as you don't have to stop. Just rev match your shifts. Hold the clutch pedal down the whole time and it will probably break free with some heavy throttle...

I went around the block. Luckily did not have to stop. Went up to 5th holding the pedal and it did not break loose. Tried holding the throttle, tried stabbing and coasting, nothing. Only got up to about 50 or so. May not be making enough power that low in the RPMs to break free. I think I may try again over the weekend at a higher speed.

Exact same thing happened to me after a burnout Nd launching from about 5500rpm. I drove it home by rev matching my shifts. Looks like I'll try to get it in 5th and stab it a few times to see if it'll come free.

Wow...2009 to 2012...zombie thread back from the dead. A clutch will not stick unless it is super-heated to the point that you actually begin to melt the disc facing. Then upon cooling the disc can weld/bond to the corresponding surface of the plate or flywheel. Do you have a line-lock? What was happening when this occurred?

FYI: I sent the clutch to Spec. The friction disc welded to the flywheel. They didn't warranty it (it was pretty new) but they did work a deal with me that saved me some money so I was happy in the end. Sorry to all it took so long to reply. I totally forgot about this. I ended up replacing the clutch and sold the car shortly after.

Word for the wise. Be damn sure you are in the water before heating them up or if it does stall out, wait a bit before trying again. Maybe you didn't melt it the first time, but the second time it will have more chances cause the heat will still be there.
