Have a 2005 Chev Avalanche 350 V-8 with 95,000 miles.
Have slight vibration at idle and when reached 40 mph.
Had Tranny and Torque converter checked. They are fine.
Engine and transmission mounts were replaced.
Universal and CV joints replaced a while ago.
The mechanic is now saying that vibration could be internal to the engine.

I see that you’re already working with your mechanic to diagnose the vibration concern you described. If Customer Assistance can help you work with your dealer towards resolving this, please email Christina with your name, contact information, VIN, and dealer name.

hey everybody. I have a 02 avalanche with 146,000 miles on her. bought it back in July of 2011. All stock besides tail lights, strobes and dash lightbars. only put just under 3000 miles on it now since then. i noticed when going after being stopped at a light and then go at a normal slower speed instead of hammering it down that when it shifts i hear a noise. but if i give it a lil more gas after stopped it doesnt seem to do it. idk the owner before me has all records of everything done and i keep it well maintained to checking all fluids every week to even cleaning her 2+ times a week. but today was the most i noticed by far when i drove for about a hour. A few side streets and about 20-25 mins freeway But i only noticed it def. when it shifts from 1 to 2. My brother a mecanic so im going have him check it, but wanted to see if there was any other Av owners who had similar problems?
