Chelsie, On your 2006 Cherokee: It's best to have this issue checked by a transmission shop. When all the lights are on there is a code(s) in your vehicle's computer. A professional diagnosis which will include scanning is needed to determine the type of transmission issue and the correct repair. Good Luck!
