    Increase the shift pressure tables, decrease the shift time tables, use shift torque reduction to fine tune feel.

    Increase the TCC min pressure table.

    Make sure all downshift speeds are lower than their corresponding upshift speeds (in the WOT shift parameters and the PT shift tables).

    Make sure the TCC release speeds are lower than the corresponding apply speeds.
