slow down shift

Hi

I have a 06 Focus ZX5 automatic with only a few hundred miles on it. Noticed, that in one instance when I brake hard then ease up on the brake and come to a stop the tranny hangs in second gear too long, and then slams in to first giving the car a noticeable jolt. Other times brake hard then do a rolling stop and than back on the gas the tranny hangs in second then shift to first gear very abruptly. Under normal braking the downshifts are smooth.Asked the dealer about it but they say there is no technical service bulletin issued by Ford and they believe this is normal for this tranny. They did not sound too convincing, so I would like to ask you guys for your opinion on this shifting pattern for the Focus. Is it normal or I have a bad tranny? Thanks for your help.

Hmmm whenever I press the gas on my zx3 when coming out of a turn it goes steady and then it jolts and takes off. But when I brake at a light and then take off its fine. I'm starting to think its the cv joints maybe?
