In the Morning transmission hesitates to grab first gear after backing up

Hello, just wondering about my SUV. When backing out of my driveway in the morning it sometimes hesitates to grab first hear when I put it in forward. It does not seem to have any power when pushing gas pedal and then finally starts moving and driving normal. I do not really have any other issues with it. It normally runs really well. Only other thing is when I brake really hard it comes to stop and then sometimes shuts off.
