8 speed transmission changes

[genpk]

Have an interesting issue with my 2015 gc diesel.
Every now and then i get a momentary drop in revs, almost like a flat spot in between a change of gears , just for a second or so.
Only happens odd times and sometimes between 2nd to 3rd, other times 4th to 5th and when the engine is at low revs.
When driving it a little harder the changes are all smooth and fine.
Had the trans pan and oil changed about 6 months ago.
As said, only does it every now and then- very strange

I would firstly be checking the fluid level in the box...

Funny, I think that sounds pretty similar to what mine does occasionally - also had the fluid and filter done 6-12mo ago... Likewise, seems to be no real pattern to it, only happening every now and then

I have not experienced this yet on my diesel. Possibly it is shifting up quicker making you feel that way? I know these things shift up so many gears in very low speed to be economical if you are not putting your foot down. And again even with the foot down it does not hold gears like the petrol versions just lets the torque push the car keeping revs low. But you probably know all this already just my thoughts
