It's a 2008 4.2l 4wd

The last picture is what I'm looking for, first picture is what I'm seeing...
Looks like it's under that plug...but idk if/how to remove it without breaking it...

The later 4L60E transmissions have a speed sensor of some sort there, only way to get to the boost valve on those transmissions is to pull the trans, pull off the pump and replace it with the pump outta the vehicle and trans. To the best of my knowledge there is no way to remove the electrical connection.
