TCC Lockup/Solenoid

[Sweet6]

My ECM is showing the TCC is lcoked but it is not locked. I verifed that there is 12 volts going to the plug on the trans. I did an OHM test between A and D on the trans connector itself and did not get a reading. Any other tests? It seems like a bad solenoid. But wanted to make sure before I do anything.

Do you have any voltage at pin "F" on your ALDL connector?

I will check that. Which one is F? Top right?

just change it out. I did it for $75 with parts and mine works perfect now. Huge relief

Top left. "A" is top right.

Swapped mine out a few weeks ago while changing the filter. Wasnt locking as you described and I had verified voltage on tranny plug., def works now.

change it out.

I checked F and did not get 12 volts. But then I tested another car on which the TC locks up and there was not 12 volts on F either. So I am not sure what is going on now.
