Default changing park to drive shift pressure (HELP)

ok .... everything in my tune is dam near perfict but the only thing i cant seem to figure is sometimes when takeing the car out of park the transmission seems to shift too hard

again all my other shifts are good (firm but not overkill) the only shifts that are too hard "sometimes" are takeing the car out of park or netural and putting it in drive

is there a way i can adjust the pressure for putting the car in drive without loosing pressure up to

My guess is you might have to play with the force motor current for that one since there is no direct table to adjust for it. What year is your car and what do the numbers look like for the 0kPa Line Pressure row in your FMC table? I would try increasing them by 5% and see if that helps. Just keep an eye on shifts while coasting as well since all shifts with no throttle will be affected by this change.
