I realize this is an old thread, and noticed you fixed your issue.
I have noticed mine shudders at the same speeds, but when the torque converter unlocks, upon light acceleration. I am currently running a stock Edge EVO on Lvl 3, and Lvl 2 when I tow. They both do it, but I also played with the shift firmness settings, it is still happening. Is this something that the Custom tunes I am waiting on might fix, or is this commeon in an 07 Screw 3.73 Rear end 2WD?
