How to check if solenoid for TCC is energizing

I did a search but I am not clear on how you check if the TCC solenoid is energizing.
As far as I can tell you turn the power to the on position but with the motor off. You connect pins A & D to energize the solenoid and then you measure the resistance of the connector pins attached to the case of the transmission (on the Drivers side).

Which connectors do I test the resistance of on the transmission? I think there are 4 there.

Check the resistance between A and D.

Re: How to check if solenoid for TCC is energizing

one way you can see if your lock up is working is drive the car up to 50 mph to make sure its in 4th gear. keep the car at very light throttle to maintain
50 mph at the same time press the brake pedal just enough for the brake lights to come on. if you have a tach you should see the rpms drop about 300 rpms. if not you should feel the car have a slight miss the you tap the pedal. i do know that the tcc power circut is ran through the brake pedal switch.
