Over the last week or so, when starting from cold, I've noticed that going from 1st to 2nd, 2nd to first, and 3rd to 2nd are a bit notchy, with resistance to getting into gear. Once the car has warmed up though, it's as smooth as Silky the silkworm sleeping in his cashmere-lined sleeping bag.
Anyone got any ideas what this could be? The car is under AA gold warranty.
