One explanation for the Pilot to say -"its stuck, it wont move etc" is because the pilot has firmly gripped the 'Stray' No1 TL and is exerting too much of a sideways force on the lever thereby Jamming it in position.
Please read the preliminary transcript above. Contrary to what has been said there is no such indication of a stuck TL for the time being.
TAM 3054 was a manual ldg in config full with headwind 330/8.
