A small number of J8 Vehicles built as over-the-road units for non-reg BUX markets and sold to US-based mining operations with the intent of re-programming the diesel PCM to limit vehicle-speed in the mining environment. The discretion of which mining flash is to be used is left to the discretion of the operator.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10139879-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2014/MC-10139879-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10139879","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"JEEP","model":"WRANGLER","year_from":2012,"year_to":2014,"match":"exact","vehicle_ids":["2012_jeep_wrangler","2013_jeep_wrangler","2014_jeep_wrangler"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
