4l60e force motor negative

[busted axle]

i am just curious what effect the force motor negative table has and does it need to be the same as the positive table i have a 99 silverado p0411

Not sure what it specifically does but I have never seen a calibration where both tables weren't the same. GM eliminated the negative table on 2001 and up calibrations.

I do believe it is for off throttle Coast down pressure but I am not sure trying to figure it out

For what reason? Sometimes to figure out tables you just have to try changing them and see what it effects. But apparently the GM Engineers saw a reason to set them both the same.
