Glad you are ok. Thank you for posting this important safety issue.
Its about the on going issues with this non Honda outsourced 9-speed transmission that is to blame.
There are many reviews about it and including the 2019 year. They only fixed it with starting
off in 2nd. The other issues are still there. It took those few seconds to decide to drop one or two gears.
Called gear hunting. The Honda made 6-speed doesn't have this issue. That is why......
The 9-speed is quicker 0-60, but slower in the Quarter mile, and at passing cars (Like you did)
compared to the well proven 6-speed. Also makes you wonder why Honda came out with its new
10-speed, which is much better on the posted reviews.
For your own piece of mind. The lower 3 trim levels of the Honda Pilot have the proven and
better transmission. Maybe you can ask for a trade in at the Honda dealer. Those Pilots are
a 100% Honda, and so are the upper 2 trims of the Honda Odyssey. Really no reason to leave Honda for one Transmission's bad history, even back to the 2014 jeep issues.
