Hi new to all this audi driver for 7yr looking to upgrade

I currently have a 53 a4 1.8T iv had her for 7 yrs now and just fancy a change iv been looking at a 58 A4 cabriolet accordingly it's a 1.8T but it only has 5 gears is this normal? I though it would be the same at mine with 6? Might sound like a daft question
