Narrative:
After takeoff at mia, upon flap retraction, we noticed that amber in transit light was staying illuminated. We kept the speed down to 230 KTS and got vectored out west as we ran the checklist. After running the emergency/abnormal checklist we ran the normal checklist and set up for the approach. According to the emergency procedure we landed flaps 15 degrees with the #6 slat mid way out with no rolling tendency. We landed at about 143000 pounds with a normal touchdown. We then coordination with ramp for a gate and then called dispatch for a new piece of equipment. Maintenance noted this was a repeat item.
