Hesitant on 1st to 2nd
 

Hi folks. Lately my 8 has started to hesitate when driving off, but it's fine after 2nd gear or drive off? It's currently got 122k on the clock so could this be an issue? I don't have any paper work to suggest it had a gearbox flush in the past. Also if the box was faulty would it not be on all gears? Help
