Ok guys, I have a problem and hopefully someone will have an idea what's wrong. More often than not, when I'm in 1st gear or reverse and I'm idling real slow, about 5 - 10 mph, and I push the clutch in, I hear a loud knocking/clunking noise coming from what sounds like the area in front of the tranny. It also seems to be more prevalent if I'm on an incline. Any ideas?
