after my car has been sitting in the sun all day while im at work it doesn't really slip at all until i drive the car for about 10 or so minutes. Them it starts slipping. This only happens in the warm summer months that i've noticed. Also it seem worse with more humidity. My drum brakes also start squeaking when the humidity gets high. Lately the humidity has been down and my brakes haven't been squeaking and my clutch has not really slipped all that much. I checked the fluid level and its full. The pedal feels fine. The clutch itself is about 2 years old and has probably 20k - 25k miles on it. Is the clutch just wearing out? or is there something i can do to fix this. It also doesn't matter what gear i'm in as far as the slipping goes. I hope someone can shed some light onto what is going on with my clutch.
