It sounds like your kickdown linkage needs adjusting correctly. Keep this in mind. You can certainlt **** manually, however, that does not help the throttle pressure at all if the kickdown linkage is not adjusted correctly, so essentially, all you are doing is taking a chance with transmission failure. Without the kickdown right, the throttle pressure is still low and not holding the clutches together very well and you are shifting at over 5k. Not a good scenario.
