08 Impala 3.5L Trans Leak

OK i got a 2008 Impala S and it just started leaking trans fluid from these two tubes that come from the front of the trans and turn up into it right in front of the trans pan, it also started kicking into gear when it warms up especially when moving from a stop. Does anybody know what these tubes are, have not had time to trace the lines, but noticed them wet after quick inspection under car, they ave what looks like a black rubber or hard plastic boot/grommet where they connect into. I'm fairly confident i can do the work my self but i don't have any idea of what the part to order would be called

Trans Service is up to date, done about 4 months ago, was expecting another service soon, but wasn't anticipating the leak

Thanks for any help
