2000 f-350 7.3 hard shifting after rebuild and now won’t shift into 2nd

Hi new here .. got a 2000 f-350 7.3 had no tranny in it when I bought it. Has ts6 tuner but only 3 Positions work on a 4 position knob? has shifted hard into 2nd and 3rd since I put in rebuilt 4r100 tranny.its the worst when first taking off from a start up ..1rst gear seems to drag out longer than I think it should going high into rpms before shifting to second .. if I lift off throttle it ####s sooner . now after 6k it stoped shifting into 2nd gear at all and just redlines .. I can shift it into 2nd gear manually with shifter .. trying to Diagnose any help will be appreciated

Get the codes read. Without the codes, all anyone can do is guess.
