Piece of cake. The TCC apply rate can be changed to apply the clutch softly. BUT "burn time" is not good and the longer the apply takes to reach 60+% duty cycle the more friction material damage due to heat. I use the value of 60% because it is usually enough to create a lock and hold condition depending on EPC or "line pressure".

Unlocking the TCC on deceleration is also possible. Heck, lots of PCM strategies out there do that anyway. It's possible to change a few parameters and get even a PMT1 to do it.
