4L80 shift question When in 1st gear, my 4L80 shifts to second gear. I don't want it to do that. I want it to hold the gear it is in. My last one was like that.
Any tips on what to do. I am using the same tune for the "new" 4L as the old trans. I would rather do it internally than change the tune.
Thanks

Its a super easy fix in the tune if you have HP tuners or know someone who does. or if older 93 to 96 Tunercat otherwise Transgo kit

I have HPTuners. I have seen the write up on Gen 3 computers using the Urban shift. I have a Gen 4 E38 and 2006 4L80. The Tune does not have the urban shift button. Is that the same as D2 ? I have Normal, D1, D2---Pattern A, D2---Pattern B, D2. Pattern B has the D2 populated with all 318 and not let it shift. Pattern A, D2 has all 0's except the last two cells. Is this where I need to shut off the shifting?
Thanks !!

Beyond that you will need someone with HP to answer that question.
