Gearbox playing up slightly
Right as rain for most of the time, but just occasionally pulling off after almost stopping, or only stopping for a moment, there's a clunk as gear is engaged and the car then moves off
Also when selecting reverse, it's a bit reluctant to engage, and when power is supplied, gear is selected with a clonk and the car moves off
All other times the gearbox works flawlessly, with barely any indication that gear changes are actually happening
Will replace the gearbox oil filter and auto transmission fluid soon - searches on the web suggest that should sort it out
