Recently, I noticed that my car slid backward down the driveway overnight. I've always put in first gear when I park w/o the parking brakes on (I do it now every time since I began noticing it). So I thought I give it a test. I came home one day, put the tranny in first gear and shut off the engine. My car started sliding backward. My driveway is on an incline. Is it my clutch that is giving out? I don't have a problem with pick up when I'm driving. Does anyone know what might be causing this?
