Cummins 2006 5.9 swapped to a 2016 6.7
I?m new here and thought I?d see if someone out there can help me. I swapped a 2006 5.9 to a 2016 6.7 Cummins. As soon as I hit 4th gear, my check gauges light comes on and my temp pegs, yet it?s not overheating. I loose massive power. I threw 6 codes, P2609, P0234, P0116, P2509, P0483, and P0217. The check gauges light comes off and temp goes to normal if I pop it in neutral and cost for few. Why would this be happening and how can I fix it? Thank you all in advance!!
