how to adjust the shifting cable? on 1997 Chevrolet Lumina

when i have it on park its actually on reverese, when i have it on neutral its on overdrive, so basically everything moved up.
I need to adjust it to be back how it originally was because my reverse lights stay on when i turn the car off and it kills the battery. so how do i go about adjusting this? or would i have to change the shifting cable itself?
