On my truck it varies. Sometimes the shudder is very faint, I initially dismissed it as being the exhaust, I have a bit of drone with it dumped before the axle, or rough road, Sometimes it feels like running over a series of rumble strips, shakes the whole truck. He might not have even known it was starting.

Feed got it right. It was doing it before it was tuned, but at that time it was infrequent enough I thought it was rough spots in the road. Now it's almost every time I go those speeds and it's getting worse :-/

With all the known issues with the torque converters/TCC, I would hope they at least cover a new converter regardless, good luck. After I get my alignment straightened out mine is going to the dealership for the same thing and the constant service stabilitrak message. I've been riding it out hoping it gets really bad so they can't deny there is an issue, but it's really inconsistent.

You really don't want it turned off on these transmissions, they wouldn't last very long. Mine was turned off for two weeks and I could see it how it would destroy itself.

my understanding is EFI live is on or off,HP tuner allows %

my thought could be with EFI live,one might turn it off then back down all the pressures because its brutal with TM off.just my thoughts
