  Well, 2 no-bid contracts to donors didn't seem to result in a good job...

  I have a 2020 Sierra with the electronic latch. Can I switch that out and put a regular latch in.

  Yes it’s damn shame what vandalism can do. With defacing, putting chemicals on the grass and possibly including algae in the pool. I’ve taken care of a few pools in my life algae can be a problem. They’re ways to eliminate the problem. I’m sure the problem will be solved. Some people just don’t like nice things. Or is it TDS?

  ouch to both. $650 for hooking up their computer and hitting a "reset adapts" button is ridiculous. and I would want to know why they think a new transmission is required besides the manager wanting a bigger bonus this quarter.

  Thanks everyone for your input on this subject. It was very entertaining but not educational. Bottom line. The GM 6.6L should not consume oil, which it does, no matter the driving style. Only time will tell if it lasts past 100k. I am hoping 200k+. GM needs to get back to the piston rings and top fuel injection which works and has been proven. You may now move about the cabin.
