Charles Kistler Posted May 10, 2021 We have 2012 NV 3500 every once in awhile we get a shutter / shake. It last about 10 seconds and than goes away. When this happens I can put the transmission in neutral and the problem stays. I can rev up the RPMs with no change to the shutter / shake. It does it when I'm towing and also does it when I'm not towing. Had it back to the dealer they found nothing. They did a transmission service and it still happens. Where should I start looking?

radin2son Posted May 10, 2021 What are the conditions when and where this happens? Long, fast downhill roads? If that is the case it may be the abs, warped rotors or something going on with wheels and tires. Older posts may be helpful. Quote Share this post Link to post Share on other sites
Charles Kistler Posted May 10, 2021 Up hill defiantly not the breaking when this happens It has never happened at a higher rate of speed I never really looked but would say below 50 MPH Quote Share this post Link to post Share on other sites
radin2son Posted May 11, 2021 In 2012, the tow package was an option that included tow mode, extendable mirrors, hitch etc. Do you have tow mode? Later years, this was standard with V8s. That said, I don’t recall any posts reporting a problem like yours. Quote Share this post Link to post Share on other sites
Charles Kistler Posted May 11, 2021 Yes we have the tow package. We use the tow mode every time we tow. thanks Quote Share this post Link to post Share on other sites
