    2017 Denali 1500
  1. I spoke with my service manager today about the problem and he was familiar with it and said most of the time they can flush transmission ,replace filter and fill with full synthetic fluid and the problem goes away.
  2. 2017 6.2 Denali 14k Miles I have noticed that I get this vibration on highway. It seems to me it is like a shudder when engine is lugging like it needs a leer gear . I started leaving in manual position and every time it would start vibration I would done shift to 7 from 8. The vibration would go away , then shift back to 8 and it would shudder in cycles until either accelerated or or manually down shifted anyone have this problem I believe it is transmission
  3. I still have a 2010 denali pickup with the 6.2 140,000 miles not blue smoke on start up . But on cold mornings it has a knock in engine at first start up which i think is valves ? maybe . Has been at dealer for problem and they did a decarbonization of the engine and it didnt make any difference . Doesn't use any oil and runs great . Once it warms up about 20 secs knocking/clatter goes away . Dealer said GM said that is normal . Does anyone else have the same issue?
  4. mine is blue as in oil not black . What is DI ? direct injection ?
  5. 2017 GMC Denali 6.2 , after my truck sits for a few days and i start up i notice a small puff of blue smoke coming from tail pipe. My experience from other vehicles is that is usually an indication of oil seeping past valve seats. I have noticed that on other vehicles before ,but usually high mileage vehicles my truck only has 14K miles. Has anyone else noticed this or have and suggestions if that is normal for new engines or should I be concerned ?

  7. Dealer replaced my rear end on truck and it did the same thing . I started looking and the axle was not mounted correctly right side wheel was forward to left . They didn't get it in mounted correctly . I would check the mounts where springs attach to axle. and check spacing of tires to fender wells on each side is same.
  8. Dealer called me today and said that everything check out ok on computer and that it's not a sensor or computer problem , but that something inside transmission has come apart . He said it has some metal inside and they don't know what its from unless they tear down completely . they said if they do that may as well rebuild $4000 or just replace with rebuilt $4500 with warranty 100,000 miles . 2011 4wd with 66k miles . I am thinking of trading it in . I just don't understand how a truck that was working just fine and after just replacing fluid and filter this happens.
  9. Correct fluids and full took amco they said it not shifting out of second . Said computer is telling it to shift but mechanically it will not shift . I called dealer he said try to reprogram Tcm . Amco doesn't have capability so had wrecker pick it up and take to dealer . My luck warranty went out August 2016 . My guess is the tcm is in pan and must have gotten damaged when pan pulled off . Amco wanted to pull transmission and tear it down . I didn't want to go that route yet .
  10. I just had my transmission fluid and filter changed truck has 66k miles 2012 1500 with 5.3 auto. Now it will slip like it low on fluid , but it's full . Any ideas of what happened . Tranny was fine before i changed fluid and filter . Sometimes it works fine then next time when you step on gas it just slips and doesn';t go.'
  11. Replacement of truck ? NO . AC ? NO but should fix or have attorneys send them letter
