About a month or so ago my 5 speed started to grind going into 3rd gear. My clutch is probley fairly worn. But it shifts fine if you give it alittle fuel going in to 3rd. Also when i downshift sometimes it will grind alittle. If i put it in real slow it wont grind. Do you guys think this is clutch problems or something wrong with the transmission. Truck has 90,000 miles on it.
