A computer controlled automatic transmission should actually learn how you drive and adjust to protect itself. If you drive nice and easy your transmission will shift soft and early. If you drive it like a fire truck going to a fire the transmission will shift hard and late. The computer raises the line pressure to protect itself, this makes for quick and very stiff shifts. When you clear trouble codes most newer cars reset the learn function and you have to start over training your car how you drive.
