no my shudder is constant, and i can make it occurr for probably 10 seconds, and it gets worse the longer is goes.
ive driven enough autos to know when lockup occurrs, but its not harsh like im getting.
maybe, just MAYBE, the lockup IS the problem. i can be cruising at 100km/h, i might squeeze my foot to go up a hill and it will release and the revs go up. normal im guessing? (lets assume im in D and not M) sometimes, i can be in the same situation, and it wont unlock, and i REALLY need to push the throttle for it to kickback to 4th to overtake etc.
its weird, but disabling will at least take the attesa out of the picture. assuming it continues to do it while its disabled.
i should also look at WD40ing the throttle input attached to the pedal. it might be worn or dirty down at the bottom end where its driven most
