I have just bought a second hand 2016 1.6 automatic AWD.
When cold the gears from 1st to 2nd is slow to change and even throws me forward because I’m expecting the car to change. However when warmed up, it changes ok.

I have searched and found that some advice is to change the transmission fluid?

I took it to my local dealer and they couldn’t find anything wrong with it, but did advise to change the oil in the transmission.

They did however update a couple of software updates and charged me £85 for looking at my car and the updates. Is that to be expected from updating the software? Plus they never solved the slow changing.
