It's the touring and elite models that have the ten speed - to the best of my knowledge, my '19 EX-L with navi is still the 9 speed tranny. I agree though that it is not the transmission itself causing issues, but a software issue. The transmission shifts smoothly when steady power is applied to the pedal and on higher gear shifts. It's only at low speeds when you are pressing and letting off the pedal and then pressing again that seems to cause an issue, which I'm assuming is a software glitch. Seems like the computer is thinking (technical term) about whether it needs to stay in 1st or switch to 2nd gear. Once it makes up it's mind (again pardon the technical jargon), and switches into 2nd then it tries to catch up to where it should have been already.Lilfish, correct me if I'm wrong but isn't your 2019 EX-L a 10-speed? I have a 9-speed 2018 EX and have experienced the same thing. It hasn't happened too much lately. I question whether the cause is actually in the transmission. Could it be the gas pedal software, if there is any? I don't think there is a throttle cable. The signal for more power is sent by wire instead.
