TCC lock-up issues
I just recently had my trans rebuilt, using Probuilt's Street/Strip kit, along with a Edge torque converter. Overall, it is an amazing build. However, the torque converter lock up does not work. My gas mileage is toast on long trips!
I tested the pigtail (pink/black, purple) at the cruise control switch, and it showed a solid 12 volts. I'm not sure if you're supposed to be able to hear the solenoid, I've been told that you should be able to hear an audible click. I can't hear anything when I ground A and F on the ALDL. Also the voltage didn't show any change when I grounded those terminals.
Is there anything else I should be looking for?

Re: TCC lock-up issues
Key on , you should have power on the purple wire at the connector on drv side of trans
With the connector in place ,if you probe the tan/black control wire should also have 12V which is the control circuit to ground through the ECM.
Grounding that wire (key on ) should activate the solenoid
