I wish I knew how to best describe but here goes. I recently bought a used 2016 EX-l with 30k. Regardless of econ or not when accelerating the up shifting does this odd thing where I can watch the rpm gauge bounce. The engine is similar meaning it shifts smooth but goes up but then slightly down. There isn't a noticable gear shift but on a meter you would see rpms rising but periodically dropping a little bit. Almost feels like riding waves. Is this normal?
