I have a 2006 SS/SC with the G85 4.05 LSD I push the clutch in and have pedal feel but no full disengagement. I can start it in gear and it just goes and can’t get it out of gear with the car on, and won’t go in gear while running but doesn’t grind when I try. When I have it up on jack stands and have it in gear and I rotate the tires there is very little resistance like it’s not connected to the engine and the wheels spin opposite of each other in any gear. I am at a loss with what is going on and can’t find any solution with research.
