    Default When throttle kickdown is not set at 100%

    Graph show what happens when the Throttle Kickdown tables are not set at flat 100%...

    ( 4-3 Kickdown curve has been axis-swapped to match axes of 3-4 PT Upshift and 4-3 PT Downshift curves )

    Above red line = upshift into 4th
    Below green line = downshift into 3rd
    To right of blue line = throttle kickdown into 3rd

    The blue region shows a conflict (PT upshift table wants 4th, throttle kickdown table wants 3rd).

    PCM may or may not follow the kickdown table... it won't shift when you think it should, and vice-versa.
