If you're asking if and how the shift firmness/duration will be controlled, it should be very simple(I can only assume at this point as I havn't been able to do my own). The PCS module has a number of options for input for this variable. I will use the map sensor since boost is the absolute best measure of engine load. As the boost rises the module will increase the shifting firmness through a combination of pressure and solenoid signal. Forgive me if that's not perfectly correct with regard to the tranny internals, I don't actually have to know the down and dirty of the tranny to make this happen, just have to know what I want it to do so that I can play with the pressures and durations of shifting while using map as a reference. However, you could use any input sensor you wanted for other needs, such as tps, or vss for incorporation into a TC lockup strategy, or simply have this in conjunction with a TC manual lockup switch, or have it come on based on speed, or rpm, or whatever you can dream up.
As far as the input device, I will use a joystick that's mounted on a tube that bolts to the floor right where my shifter comes through the floor now. I will use a standard automatic shifting cable to physically cycle the valvebody through P,R,N,D. For this I will physically move the joystick from left to right. So that P will be basically all the way to the left, say 45 degrees layed over toward the steering wheel, then R would be proportionatly more straight up and away from the steering wheel, N more straight up and again farther from the steering wheel, with D being with the joystick standing straight up. That way you would have a tactile reference for mode selection by simply feeling with your hand. I actually considered using a servo for this, but the user feedback on which one you were in would have depended on lights, or something much less informative than a tactile feedback like having the joystick physically moving throughout the range in your hand.
Then to shift up/down, I will have microswitches at relatively within relatively low degrees from straight up that will trigger the shifts to the module. So for me, I will set it up so that pulling back on the joystick will shift up one gear per each "slap" or tug. And obviously "slapping" or pushing forward would lead to shifing down one gear per hit. I will also have a rotary switch for switching between differing profiles that I create, so that I can have a grandpa smooth profile for cruising, but then simply switch to another profile in case I want it to lay stripes on each gear, or anything in between these, because you personally "program" the values so that it will do exactly what you want.
You also have the option of programming in full automatic shifting strategy so that if you kill the 12v power to the manual input device(joystick, paddles......) it will revert to this fully automatic shifting schedule in case you want hands-free operation just like a standard auto would. Except that you get to design this program as well so you can dial it in at any time by plugging up a laptop and changing parameters to any aspect of the system.
Check out their webpage. Powertrain Control Solutions (PCS). Their tech guys are really sharp too, so you can bounce any crazy questions you might have off of them. I will be going this route as soon as I have time and can afford a BTS. /ubbthreads/images/graemlins/tongue.gif
