Catman Posted November 11, 2019 Share Posted November 11, 2019 (edited) Lightning bolt on dash but not the engine light. The problem that I feel is that the truck is not going into gear good first/reverse. It will go in gear with a clunk then seems to work fine. I also can’t switch between n2/n1 while lightning bolt is on. It only stays on for a day or two then goes out and all issues are ok with going into gear. Almost 400k on truck. Any ideas? Thanks in advance Edited November 11, 2019 by Catman Quote Link to comment https://www.bigmacktrucks.com/topic/59809-2016-cxu-613-mp8-auto-lightning-bolt/ Share on other sites More sharing options...
upsman Posted November 13, 2019 Share Posted November 13, 2019 Engine symbol light only for emissions issues. Lightning bolt means electronic malfunction.
