My wife's 2011 Tahoe has the ZW7 RPO code but "standard" blue rear shocks. I'm not sure what the Premium Smooth Ride option is supposed to accomplish if they use standard parts.
I don't even know why the put such a high gear in a vehicle this size. My wife's 2011 Tahoe has 3.08's and it really needs a 3.23 minimum. The 6L80E has such a deep overdrive, there's no reason to run such a high ratio.
Ok, I finally figured out the problem. That's the good news. The Gray 16 pin to Black 20 pin conversion harness is wired incorrectly. The bad news is you'll have to remove all the components to gain access to the conversion harness to remove and fix it. All you have to do is repin the Black 20...
Typically slow and very expensive shipping compared to other places. I actually have a brand new GM cooler kit (if your Tahoe has the 4 spd auto transmission)...if you're interested.
2012 HDD Nav install, DVD remote inop *UPDATE*
I installed the new 2012 HDD Nav/DVD unit in my wife's 2011 Tahoe, everything works great except for the DVD remote, any ideas ?
I would'nt let JL work on my lawnmower, much less a $40K+ vehicle. There are "Multi-vehicle" universal type anit-freezes out there. Good luck on determining if that's what they actually use.
