Actual pics? Those are actual pics of my truck...
No, zero, zilch, nada vibrations at all and the transmission is working very well. Granted, it has 288 miles on it so far but I actually really like the 8-speed for shift quickness. I think it doesn't suit some peoples driving style but I've had no trouble.
Well, I'm out.
Traded the GMC in on a new truck and I am very happy about it.
Good luck guys - I really, really, really hope we do end up finding a solution...
I'm so frustrated with the vibration (now 57,000 miles worth of vibrating) but I can't find a good solution... Looked at a ZR2 today but... hmmmmm
I can't believe we haven't figured this out yet!
If the '16 doesn't vibrate that means it CAN be fixed, since it's "the same truck" with... something... different that has fixed that. At least, that's my hope. My '14 vibrates at 70+ BAD and has done it for 40,000 miles. Posts like yours, that document what has been changed and what has/hasn't worked are very helpful. Keep us updated!
