Take it and have it checked for codes. It sounds like the trans is overheating and needs repaired before it is ruined.
The overdrive light will be off when the overdrive switch is pushed in. If the light flashes then that's a trouble shooting code.
The check engine light on a 2005 Jeep Grand Cherokee looks like this... Here is a link Check Engine Light It looks like a little yellow engine.
How to change the brake switch on a 2004 Jeep grand Cherokee Laredo
When my jeep cherokee alternator went bad, the check engine light came on and I didnt have a clue what was going on until my volt guage was reading in the red zone. When I replaced my alternator, the light went off. So in my opinion i wouldnt consider the check engine light as a alternator light.
I dont describe things well but, your transfer case is underneath the driverside of your jeep to the left of transmission if you were facing the steering wheel from the driver sear. It looks like an extension or addition to the transmission. While underneath the jeep follow your front driveshaft back, what it connects to will be your transfer case.
speed sensor on top of transmission,if the speed sensor does not work then the shift inside the trans is broken and trans will need to be rebuilt
It shows that there is a problem with the transmission. Just like the check engine light, the overdrive light has codes that tell you what is wrong with the transmission and the various components connected with it.
blinking overdrive light indicates a transmission problem. take car to a transmission mechanic
There is a problem with the transmission.

An OD sensor determines when your vehicle is in overdrive. If the overdrive light comes on in your vehicle, then there may be a problem with the transmission.
Transmission Problems, you shouldn't be driving with this on!
When it has been pressed and the light is on, the transmission is limited to 3rd gear.
The Overdrive Light flashing indicates an internal transmission problem which could be caused by anthiny inside the transmission. Most likely the transmission would have to be removed and taken apart to find the problem.
Are you sure you don't mean OD off light? If so, that means that the overdrive gear in your transmission is not activated. On automatic transmission models there is a button on the end of the shift lever which controls whether the transmission is in overdrive or not. Push in on this button - the light should go out and overdrive will be activated (which will definitely give you better gas mileage).
The overdrive warning light might start flickering when you are driving because of low transmission fluid. This light could also come on because of tension on the transmission while you are towing a boat or trailer.
Take it in. There is either a problem with your transmission or with the overdrive switch itself. Overdrive switch should be a lot cheaper to fix. I'm assuming the light not only goes on, but the overdrive physically turns off as well when the light is on.
