    I have a 2000 silverado 4x4 automatic with small v8. I've recently noticed a slight vibration with speed in excess of 30MPH and it appears as though my transmission is making a "clicking" sound when taking off. At first the clicking would go away when in either 2nd or 3rd but now does it when downshifting as well. Any help would be great...

    Welcome to the club. Check you front CV joints. If there worn they can click at anytime. You'll here them more when going slow because of less engine noise.

    Also U-Joints... Especially since you mentioned a clunk when taking off.

    Sometimes the clunk taking off can be the chain in the transfer case being wore out.

    The rear u-joint from the drive shaft to the rear axel was shot. Popped it off and the bearings were nothing but metal dust. Thanks for the help folks...
