Harsh Gear Changes

tomred

Hi,
I have a AT 370z Roadster (2014).
I am the second owner and I have noticed for a while that the changing of gears using the paddles is a bit harsh and it seems very occasional it slips.
The first issue seems mainly 3rd to 4th it is most noticeable on, it is like a real ker-chunk change (no mechanical noise) but seems real brutal.
Second issue happens rarely and happens in auto (noticed it 4-5th) and feels to me like clutch plates slipping as it changes revs high for a second and then is ok.
PS change down is fine and it has done 60k miles.
I live in Dubai so it is very difficult to get real mechanical advice as main dealers are worst in world (will change whole suspension arm just to change bush and you can't buy just bush!!!) and independent don't give you impression they really know what they are talking about.
