Transmission switch

What is that name of the switch that commonly fails in the tranny, NTSBU or something like that. I searched it and think i have the letter jumbled or something because i am getting nothing and know there is a zillion threads here.

Reason being is i am looking at a Duramax 2004.5 LLY with this on the mechanical condition.

Notes: Transmission trouble. Does not always go into gear when drive is selected. No other defects

wanted to research the switch to see if this could be the problem.
