Not 100% sure just an oil change I think

Got a 2010 Audi q5 2.0tdi Quattro it’s auto 7speed I think the clutch is going. It seems like it’s slipping bad certain gears it don’t do it like in 4th or 6th and sometimes 2nd but 1st,3rd,5th and 7th it just revs right up and then it comes up “gearbox malfunction you can continue driving (limited functionality)” if you put it in manual it will let you put your foot down abit more in a few of the gears especially 4th and 6th but still slips and comes up with malfunction. Does this sound like the clutch is going ? And how would I know which one to buy to replace it with. it was gearbox serviced about 1 month ago not long after we noticed it started slipping and the malfunction started coming up. any help much appreciated want to figure out if it’s easier/cheaper to replace the clutch or the gearbox with a second hand one
