The 14-16 have had "chuggle" issues, mostly resolved with a TSB requiring dealer to reprogram the computer, theres a big thread on here, it should be easy to findI've got a 16' with approx. 30k and have noticed some sluggishness and odd shudders here and there. I was my understanding that this issue was more on the 8-speed trans. Has anyone else with earlier trucks had issues?
