    Decreasing shift pressure in the 4L60E

    I have a built 4L60E with a 3000 stall, the builder said he bumped up the pressure when he built it (said it is one of the few thing you can manually adjust in the tranny to a degree) down low rpm's it shifts kinda hard and up top not hard enough, I have adjusted the "shift pressure table" and don't want to go any lower on the low end of this table, I should be able to take care of some of this both ways on the low and high ends with the "force motor current table", just not sure how to adjust it, can anyone help?
    Thanks

    I also have the same issue's with my 4l80e. Did you take out all the torque management also? I can't really find a proper way to adjust the shift pressure tables when you remove the TM.

    Yes I took out all TM.

    Try increasing the values in the low end columns on the Force Motor tables.
