Exactly. I am actually surprised how much throttle it takes for my Matrix to unlock the TC. I'm guessing around 25% and low revs, and maybe a bit less at higher revs. I plan to make my proposed control circuit unlock the TC at the same throttle % as the ECU would to avoid any possibility of damage. Still working on the control circuit because it's still not right. Tomorrow at work I'm going to make my two relay override for some preliminary testing:

When the control side is grounded, the first relay breaks the connection between the ECM and transmission while the second relay creates an artificial circuit to trick the ECM into thinking it is still connected to a solenoid.
