2018 RDX transmission glitch

I have a 2018 RDX because I wanted the 3.5l v6 engine that is tried and true in honda/acura vehicles. I have experienced a "very intermittent" Transmission problem where the vehicle will begin in 3rd gear and after getting up to speed and when shifting into 4th, it feels like a car hit your vehicle from the rear end it shifts so hard on each ensuing shift to a higher gear.
I cannot change the gears with the paddle shifters.
When I move the shift lever to manual gear selection, it does not function nor do the paddle shifters function while attempting to drive it in in manual mode.
I have been able to pull over, turn the vehicle off, and it seems as though the electronics system communicating with the tranny, "reboots" and then the car runs perfectly again.

I have experienced this 4 times in the 17 months I have had the vehicle. I have taken it into the dealership and of course, cannot replicate the problem while at the dealership.
It is my sense that this hard shifting will certainly damage the transmission if it happens again or more frequently in the future. At this point it seems that my only option is to but the extended warranty with the hope that when the transmission is finally damaged enough that it needs replacement it will be under the extended warranty.

Does anybody have an idea of the cause of this intermittent transmission malfunction?

Sounds like the dealer needs to reprogram the transmission. I think they call it "flashing?" I bought a new 2018 RDX over the Honda CRV because of the V-6 engine - which turned out to be an excellent decision. I have not regretted buying the Acura. I kept my RDX for about a year and put 17,000 miles on it, then traded it on a new 2019 Acura MDX. Anyway, I never had a bit of trouble with my RDX transmission - or my MDX with the 9-speed transmission for that matter. I would agree with you that this "hard shifting" might damage the transmission. Good luck with this - hopefully the dealer can pinpoint the problem. Please keep the group posted.
