Hey Rick, I'm still having a problem figuring this out. I have a ecm on the way so I wanted to check some wiring. I have 12 volts at the brake switch and it goes to 0 when the brake pedal is pushed. On the 4 prong harness, I have power to all pins on the wire harness except for pin D. When I give power to pin A and try to ground pin D to the tranny, nothing happens. I also do not have power at the aldl connector. So I dropped the pan again and checked for pinched wires. I didn't see anything so I took the tcc solenoid out. With it out if I connect the power and ground, I do not hear a click at all. Does that mean it's bad? And even if that's the case, that means that something must be messed up with the wiring outside the transmission. It only occurred after I installed a shift kit and wired the tcc solenoid up backwards (i bought a new one to replace). So I'm not sure what else because nothing else was touched.
