Challenger Clutch Problem

As an owner and not a mechanic, I have encountered, over the internet, about a dozen complaints about Dodge Challenger clutches failing before they should have,  This does not involve the discussions about the problem of spline lubricity, which appears to have been addressed by the manufacturer, or problems with the hydraulics or actuation. Some of the clutch failures have been about no engagement (can get it into gear with the engine idling, which generally means the pads are burned due to racing or abuse) and some of these have been about no disengagement (cannot get it into gear while engine is idling, and can when engine is off). The following discussion is about the latter: no disengagement. One poster complained that there was no spring in the pressure plate. Same thing. A few more have complained about warped diaphragms.  Same thing.  This problem is typically due to a failed fulcrum ring weld which shifts the fulcrum thereby disabling the lever action of the diaphragm fingers. The fulcrum ring is a structural component within the pressure plate assembly.  It is not a moving part and it is not a wear item. The weld fails because it is weaker than the surrounding base material and is a geometric stress concentration point.  This website is to show you what to look for in those instances.
