Volvo V70 D5 185 HP AUTOMATICs ruptures when switching…

Hello, for some time now I find that the gears of my V70 D5 EZ 2007 automatic partly quite hard jerking in. Butter soft is really far away. No matter if warm or cold. It cracks quite strong. 173,000 km it has down! Does the software update or similar need? Would be really grateful for an info. PS: Have also 6 months used car warranty. (????!!!) 🙂
