I learned this as well.

For those that try to unplug the shift indicator switch on the trans, the plugs are "glued" in for some reason. I figure some one at GM thought they should keep contaminates out.

I learned that if you heat the switch with a heat gun or blow drier, the plugs will release. This will have to be done each time you unplug as the glue will adhere once the plugs are inserted.

Gregski found the easiest way of all. Replace with a non-glued switch and plugs.
