I have a 2007 JKU 2wd 6 speed. This morning I jumped in it, started up just fine, pushed the clutch in and tried to put it in gear and it wasn't having it. I killed it, put it in gear then started it and it struggled. I couldn't let off the clutch once I had it in gear nor would it come out of gear. I have been told to check the fluid for it, but where do I find the reservoir for the clutch itself, aside from the brake fluid reservoir? If anyone can help or has an idea, i'm all ears.
