PCM pressure learn?

Has anybody heard of this? After installing Transgo the computer sees the increase in pressure, over some time period and lowers line pressure?

Nope. The adaptable shift parameters are pre-set tables, and cells are switched purely by driving conditions. When the table tells the PWM solenoid to go 100%, it's 100% line pressure, whatever that happens to be.
