2004 Jeep Grand Cherokee V8 All Wheel Drive Automatic 124000 miles
My Grand Cherokee will change gears in overdrive mode very often on interstate highways which are fairly falt here in North Florida. Trans fluid fine, serviced at 100,000. Levels full and clean. Seems to get worse as car gets really warmed up after about an hour of driving. Today engine light came on. I took it out of overdrive and came on home (200 miles) No signs of overheating or smoke. This happened before without engine light coming on. Coincidently, today radio panel would not light up or change channels after this happened? Do you think this could be a computer problem or a real transmission problem. Will change in and out of lower gear several times in 5 or10 minutes. Sometimes more frequently once it starts. Don't trust my jeep dealer to be honest with me and lookin for help.
