I wanted to alert you to an issue I had with our 2015 Acura MDX transmission. A few months ago I noticed that the tranny would flutter between gears at about 40-50 mph or about 2200 on the tach. First the dealer told me it was going to be an $800 job but I told them it was a certified used car and might be covered up until 100,000. They came back to tell me that Bulletin 16062 covers the issue up to 85,000 miles, including a software update and replacement of the transmission fluid with "fluid plus." And there was no cost. Perhaps you don't have a problem, but I wanted to let you know about it just in case.
