shift patterns with pin 71 and pin 31 questions

These options enable the various shift pattern modes within the PCM.
Note: J1 is the 'BLUE' connector on the PCM.
Switch types used must be momentary connect to ground.

'No Switch' = Performance mode via a switch is not functional.
'One Switch' = Performance mode via a switch can be activated (J1 - pin71).
'Two Switches' = Performance mode via a switch can be activated (J1 - pin71), and Manual Mode can be activated (J1 - pin31).
'C2 Data Bus' = Shift pattern modes are sent on the data bus to the PCM from another module, eg - BCM.

Only the following values may be entered into this table:
- No Switch
- One Switch
- Two Switches
- C2 Data Bus


I get the above on the transmission calibrations general parameters for shift pattern select. What does this mean? Adding a button for pin 71 give me a different shift pattern only or does it effect other things? Adding a button on pin 31 what does this do? Does it manually shift the transmission when I press the button on pin 31?
