Here are some pics and vid of installing the Kickdown Solenoid. Got a great Used one from Landseer

The removal is to use a 3/4 closed end wrench. I was able to remove the old one from the bottom after the bolt fell out. I installed the one (white writing) from Landseer from the top, then put the crush washer once it was in the area. It's an almost blind reinstall, but if you can get a flashlight from the top, you can kinda see the threaded hole.

You can do your test with a remote switch to the kick down switch under the accel pedal, ignition in the on but don't start and put the car in drive with car OFF. I actually still had it like that when I was still trying to test the solenoid out the tranny but grounded and got nothing. Once I mounted it and started to tighten the bolt, I can hear it click.
