I also vouch for a heat gun - whilst working inside a GM 4t65E transmission, its usually said that you need to say a prayer that the harness connectors dont snap where they plug to solenoids.

a heat gun works wonders here and they come out intact. - Same can be used on the interior plastic pieces.
