    hey guys. i have a 1999 silverado extended cad, 5.3 liter. about a day ago a noise started coming from my transmission that sounds like a rotational tweek or clicking sound. it sounds in all gears, while accelerating, and in idle. cant figure out what the sound is and was wondering if anyone could help in knowing what it is. please help!!

    You need to get under the truck and listen to the noise. My first thought is if it does it in all gears and park / neutral it could be a cracked flexplate or loose torque converter bolts.
