The PCM controls the ground side of the solenoids to turn them on or off. power comes from the fuse box for all the solenoids. Ignition switch supplies power to the fuse box for this issue.

It should NOT be hot with key off. Only when on.

Mike , from the first beginning I measure the voltage on the TRANS fuse , It was 4V . (I mention it with the pictures post).
I did the test with voltmeter , I didn't think about the ampere ....

Sorry .

With key on you have no power to the trans. Does this thing run? Engine? Ignition switch will not be the problem if the engine starts.
