Don't say that it cannot be in the transmission, as the TCU (Transmission Control Unit -motherboard) talks to the engine controller and can tell it too not raise the RPM's during that time, for instance would be when the transmission would be shifting between drive-gears to lowers it's RPM by 400 RPMS to shift smother. I am not saying that is what the problem is, but at the same time it could be the transmission as well as any other component on the engine.

I would attempt cleaning the throttle body. Not a difficult process. Do a advanced search here in the 2018 Forum, use user Bandit400 and search.
