After I've been driving30mins not all the time but sometimes as I'm driving the car kicks down to 3rd and the revs go up from 2000rpm to 3000rpm my mechanic has cleaned the filter in gearbox and has had on the diagnostic to see any faults but none stood out.
Have had this problem with these models before
