On easy acceleration the truck shudders, feels like its coming from the transmission, no codes thrown. Not sure what tranny it has in it. Any ideals?

It would have a 4l60/65e if its when cruising and locked could be converter shudder

Under moderate ~ heavy acceleration no shudder. Just when lightly accelerating. It has 75,000 miles on it, tranny was power flushed( @ 50,000 miles) by the Chevrolet, just started this on Tues. If its the tq conv., does it need to be replaced?

Thanks

try laying your foot on the brake to unlock the converter and see if it does it-
i think when the throttle sees a certain %, it unlocks the converter, and if its not the engine cant build torq-kind of like driving a stick car and lugging it
just a guess though
