I had the same problem , would shift fine up til 30 kph 2nd gear and just starts reving high and won't change gear , got diagnostics code it's P084B which means transmission fluid pressure switch/switch H circuit range , I've tried bringing it to dealer but a week waiting list ;( drove today for 2hrs after been parked up for 2days and had no problem but engine management light still on , if I could find the presure switch I'd replace it myself
