Diagnose clutch problem from photos

Recommended Posts

Been draggin' my LS2/240z, stock original 18k-mile 2006 GTO clutch, with slicks and as many posts have described, it stopped going into 3rd or 4th gear on high-power shifts. Around town it was still driving fine. After screwing with the hydraulics for over a week, I finally took the advice of several of you and dropped the tranny for a look around. Attached are photos of what I found. Most of the wear/deposits on the flywheel are in two places 180 degrees apart. Clutch plate looks fine by visual inspection. 1) what is the diagnosis? 2) Is this why I can't shift at hight rpm? 3) Can the parts I have be even temporarily fixed to get me thru next weekend's drag racing? I'm ordering a new aftermarket Mantic ER2 clutch system tomorrow, but I understand that it will have to be broken in over 300-500 miles. Even if new stuf is overnighted and I do a fast all-nighter assembly, I don't have time to do the break-in before next Saturday's planned trip to the strip with a friend coming from out of state. Can a pressure plate and flywheel be re-surfaced and re-used anymore?

I would resurface the flywheel and put a cheepo clutch in just for your weekend trip but it looks like a lot of heat has been put into the flywheel and especially the pp. Did the clutch slip at all or was it just your shifting that was the problem?

As best as I can tell, it wasn't slipping. When it first started acting up, I tried to induce slippage on purpose and couldn't get it to slip. I am pretty certain that I was the culpret with too much intentional slippage on the line. I was also partially engaging the clutch with the line lock on to "pre-load" the drivetrain. I guess that was a good theory, but not a good practice. Gonna have to challenge the CV axles some more and just hope for the best. Thanks to JMortensen, it is easier to swap an axle than to change a clutch! This is my very first clutch work, so I'm collecting data from folks with more experience. Thanks for your input.
