Tuners and transmissions

I am looking for some info regarding how the tuners interact with transmissions.

As far as I know, there are two tuners which interact with the transmission- SCT and Edge (and Gryphon too). What specifically are they interacting with and adjusting?

I've heard they change solenoid voltage. What does this actually do?

They raise hydraulic pressures in the trans. Does this have the effect of holding the bands "harder" so they don't slip?

They also do torque convertor lock-up, which I assume is for efficiency of power transmission.

What else do they do? What are the negative consequences?

Thanks in advance,

Edge evoloution, gryphoon, sct and phalanx all tune the tranny. The sct when custom tuned will require the strategy#.. The first part of the number is the pcm calibration and the second sequence is the tcm calibration. They can control lock up and most if not all of the tcm function. This is why to switch tunes the pcm/tcm requires programming and a reboot. Basically loading a tune with the truck off and not allowing shift on the fly.

Basically locking the converter earlier will make the engine work harder and build more boost earlier. Then increasing the line pressure through the valve body will put more pressure on the clutches to hold the power in a nutshell.
