I thing I noticed is that you dont mention any city driving,thats what your missing.I use 2 do relearn on older Chrysler trannys,and I would take them in the city,start from a stop,then start in 1st and shift it easy into every gear.Do this several times.Let it downshift by itself.Do this several times.Then go on highway,start with lower speed like 50,drive it for a mile,then nail it,go back to normal driving,take it up to higher speed,55/60 drive a mile nail it drive normal,then see if that helps.It might take some miles 4 tanny 2 relearn your driving habits
