SQ5 ZF gearbox

Hi to all,

I’m new to the club and happy owner of a 2015 sq5. I purely wondered if anyone has an opinion regarding weather or not to service the gearbox because it is a sealed unit, i know I’m kinda opening Pandora’s box because there will mixed feedback but my reasons for asking are that Audi say obviously leave alone, another well recognised an trusted garage i use highlighted doing it while its at 60k otherwise leave it, entirely my choice. But i just have some concerns that 1st 2nd is a bit grabby when changing gear, upshift an down so is this a common behaviour with the ZF or should i get it looked at look. I never experienced this ever with any of previous multi/DSG’s as been in Audi for 13 years now. Any feedback would be appreciated an hopefully I’m just being paranoid with my new purchase! 🙏
