My truck is a 1998 c1500 4.3 liter 5 speed manual 2 wheel drive reg.cab long bed. Some things that tend to bug Me about the truck is that 1 the truck tends to jerk somewhat bad when shifting gears. Its the worst when shifting from 1st to 2nd gear. 2nd to 3rd not so bad 3rd to 4th and 4th to 5th are just fine. I have noticed that it seems the clutch does not really start to engage until its almost completely released. Another thing is sometimes when backing up and I push in the clutch pedal I here a loud clunk or bang come from somewhere out side the truck.
