GREEN WRENCH LITE CAME ON
I believe it's a transmission issue, but your best bet is to take it to a dealer. Wrenches are never good on the display, and the computers are so complicated now it's tough to self-diagnose.
There are about a million dash symbols out there so you need to look in your owners manual to find out the exact meaning. Green is not bad and means that something is working, not something wrong.
It may just be a service reminder.
