A shift kit will not help your problem. Your problem is either vacuum, or the kick down cable/linkage is stuck on the side of the trans. Make sure the linkage moves freely. When you replaced the modulator did you install the valve? Did you check vaccuum to the modulator?
Dont waste your money or time on a shift kit.
Adjusting the bands and a fluid filter change wont fix your problem either.
