Sounds like revving but no rpm increase

hi, hopefully this is in the right spot


i've recently been having an issue with my acura tl '06 where when i'm driving (typically between 40-50+) the car will sound like it is revving when I let my foot off the gas. The rpms do not increase. If anything, in the video, it shows them decreasing a bit. Could this be an issue with my trans? I just got it flushed the other day and the issue persists. I can still drive the car. It doesn't seem to having a rough time shifting into gears and it doesn't jerk or have any loss of power in any gear. video link below

Welcome AF. I think I see a check engine lite on, if so get it scanned and post the code.

appreciate the welcome!


the only codes popping up are for my 02 sensors. Granted, I don't have the best scan tool so i'm not sure if other codes would pop up with a better scanner.


i'm pretty sure this issue is only happening in 6th gear. Every other gear if I let my foot off the gas, the car has no issues, but when in 6th it will always give me that high rev sound.
