You may need to learn the fine art of double clutching.
To up-shift--step on clutch, shift to neutral, let up the clutch, then step on it again, and shift to the next gear.
To downshift--step on clutch, shift to neutral, let off the clutch and rev the engine, step on clutch, and shift to the lower gear.
It takes practice, but as you get used to your truck and how it acts, you'll be able to run through the gears without making a sound.
Good luck!!
