[No one's Fool]

When downshifting my 2018 RLX, most gears do a pretty good job. However, going from 5th to 4th, the rpms get a little too high during the shift, and the speed actually increases instead of decreasing, until it realizes that it's going too fast, then it does slow down. Not too bad an issue in itself, but I just bought a 2019 MDX for my wife, and it's even WORSE than the RLX . . . same gears ! I would have thought after a year of complaints about he shifting in the RLX, they would have looked into the entire fleet. Has anyone else experienced downshifting problems with late model Acuras ?
Thanks.

Do you have a RLX with the 10AT or 7DCT? Same with the MDX with a 9AT or 7DCT?

I've noticed this issue with the MDX 9AT since it first came out in 2016. I've had a few +16 MDX loaners when doing warranty work on my 6AT 11 MDX. I like to downshift before a curve to use engine braking to slow down and engage the sh-awd to help tq vector around a curve using the gas pedal. The 9AT MDX seemed to accelerate before the curve with each downshift instead of slowing down. It felt more like downshifting on bicycle on level ground and you can pedal easier at a faster RPM after reducing the some gear resistance. I had to downshift 4 times or more to get the same engine braking effect like my 1-2 downshifts with the 11 MDX 6AT or 08 RDX 5AT.

One of the main reasons I skipped the MDX 9AT and RLX 10AT. I've been extremely happy with the 7DCT and have zero issues in my 19 MDX hybrid and 18 RLX hybrid. Both hybrids seem to always be in the right gear when accelerating, handling, and braking. The electric motors regen brake+tq vector at the same time to do the same effect of engine braking in my 11 MDX.
