Mounted on the transmission housing, the NSBU switch provides selector position information to the TCM. This switch detects the position of the shift lever and communicates to the TCM that the vehicle is in Neutral or Park so that starter can engage. The NSBU switch is known to fail, leading to issues like: no start condition, DTCs for the pressure switch, fail safe mode and incorrect gear showing on display.   \u003c\/div\u003e\n\u003ch5 style=\"color: rgb(228, 38, 38);\"\u003eFeatures\u003c\/h5\u003e\n\u003cdiv\u003e\u003cul\u003e\n\u003cli\u003eDual Connector Switch\u003c\/li\u003e\n\u003cli\u003eGenuine OEM Replacement  \u003c\/li\u003e\n\u003cli\u003eInstalled With Common Hand Tools \u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"font-weight: bold; color: rgb(228, 38, 38);\"\u003eNote\u003c\/span\u003e Please visually verify the switch on your transmission has the dual connectors before ordering.  \u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Allison Transmission","offers":[{"title":"Default Title","offer_id":45504873562135,"sku":"AT29540479","price":315.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9387\/6759\/files\/NSBU_Plug_web.jpg?v=1793122365","url":"https:\/\/ce1fdc-a9.myshopify.com\/products\/xdp-allison-nsbu-neutral-start-back-up-switch-29540479","provider":"Honey Badger Motor Sports","version":"1.0","type":"link"}
