Hi Everyone,

 

I purchased a 2016 GMC 1500 Denali crew cab 1500 with the 20" wheels. The truck now has 2,000 miles. I have brought this to the dealer 4 times to fix the issue. The first time they rebalanced and road forced. (no improvement with vibrations above 60 miles per hour.

 

The second time they replaced the 2 rear tires (they claim the road force balance was higher than they wanted). Vibration is still present in the car now at 65 mph and above.

 

I called the dealer and they scheduled a visit with the regional tech. A few weeks later I drove around with the tech with a picometer. He determined it was the tires causing the vibration. They re-balanced the tires one more time and found the right rear tire required a lot of wheel weights to balance the tire. They determined the wheel had an issue and ordered a new wheel and tire (wheel a lone needed 5 oz to balance).

 

I picked up my truck a few days ago and guess what!!!! still vibrates now at 80 mph and above.

 

Some people have been posting that michelin tires fixed the issue? I currently have the goodyear eagle ls-2.

When it shakes look at the tach and see if it's moving any. Just had mine in the shop for a bad vibration which I think is the converter because the rpms jump around about 50 rpm while it's shaking.

the converter slips in DoD to smooth out the 4 cylinder vibration. Its normal

 

Try having the driveshaft trued next, got rid of a few peoples around here.

No way it's the drive shaft, it does it when all eight cylinders are running and under acceleration at each shift. My tach never moved like this until the vibration started. If it was the drive shaft it would be constant at a certain rpm.

Exactly, I don't think there's a one cure fix all in regards to the vibration issue. I think investing in a driveline shop that specializes in drivetrain reapir might be worth it then having a dealership keep swapping out tires and balancing the wheels. Someone paid $85 to have the driveline balanced.

      Mangoal or FitcamX OEM Dashcam?

      Late reply, but yes—it works on the SLT trim. Compatibility comes down to the plastic shroud shape behind your mirror, not the trim badge itself. On the SLT with auto-dimming, it uses a plug-and-play Y-harness off the mirror/rain sensor power, so no need to run wires down to the OBD port. If anyone's ever unsure about fitment, just drop a photo of your mirror housing and we can double-check it.   Appreciate the detailed feedback on the install! On the windshield glare—we actually took feedback like yours and developed a dedicated CPL (polarizer) filter to cut down dash reflections on sunny days. If you're still running the cam, shoot me a DM. I'd be happy to send a CPL filter over for you to test out—no charge.

      Yes, every time the developer updates his code, you must recompile. I will private message you with the latest because it changes pretty much with every version.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.
