    I had the flush and new type fluid fill several weeks ago in my 2017 Colorado and the problem has not reappeared. I hope this is a permanent solution because I really like my truck. Anybody have the problem come back yet?

    You are probably better off checking the individual forums.The tranny issue is a hot topic on specific model forums. Several on corvette forum have had the flush and so far no one has reported it coming back after the latest flush. The old fluid was slightly hygroscopic, so the new fluid may solve the problem. Time will tell.

    I had the fluid changed a few weeks ago with the new (Feb '19) formula & it was great for about 200 miles, actually enjoyed driving it. But it is back to the shudder/shake that it had before & is doing the clunky shifting now too. I think it is actually worse now than it was before the last fluid change. I didnt notice the clunky shifting before it. And yesterday I backed out of the driveway, I accelerated to get it moving, then let off & when I did, it felt like it shifted gears & lunged/accelerated, had to slam on the brakes before I ended up in the road. Kinda scared me.

    maybe damage was done having the faulty fluid in there. Transmission change in order under warranty of course. Mine has been great since they did the fluid change in December
