Ive not done any auto programming and cant answer your but the table on the left does not say its vs tps. I think it might be calibration for the pressures in the force motor and shouldnt be changed. So at 102kph looking for 0 psi delivered it uses 0... pwm hz? something? and gets 0 psi actual pressure. The tables you want will be other ones.

Those tables would be road speed Vs TPS.

Most of my experience with Auto's is for the ecotec stuff so I'm not fully aware off all the different tables in 11p for transmission settings but I'd be looking for tables specific to 1st and reverse.

The main table shows 0psi at zero road speed and 0% TPS so that is minimum line pressure in the trans. There may be tables that modify the pressures when shifting.

Could you try reducing the Force Motor - Pressure (PSI) Added to see if that makes a difference?

I’m not sure what it is named in $11 but in the later stuff I tune with it comes under garage shift. There is usually a table with half a dozen numbers with something like P-R, P-D and R-D along those lines.
