Car runs great, but every since I replaced the battery, I have been stuck with the green light and transmisson overdrive. Can anyone tell me how to override the situation. The button on the shifter is non-responsive.

Overdrive Control Switch
The overdrive control switch is located in the instrument
panel. In the On position, automatic shifts
into fourth gear overdrive will occur. In the Off position,
the switch overrides the powertrain control module
preventing a shift to overdrive fourth gear range.
The switch has an indicator light that illuminates
when overdrive is turned off. The switch also resets
when the ignition key is turned to the OFF position
so that the automatic overdrive feature is restored. The use of fault codes is employed to help diagnose
the electronic components that operate the overdrive
unit and torque converter clutch.
Sounds like your transmission or lockup converter is slipping. The slipping causes heat and it is downshifting out of overdrive as a built-in protection strategy. Get the transmission looked at ASAP before you get stranded because it's stuck in a downward spiral right now. The problem could be caused by a stuck solenoid, which is a relatively cheap fix, but the more you drive it like this, the more you're working toward a full, expensive rebuild.
if it has overdrive transmission the torque convertor has a vein broke inside causing shudder replace torque convertor.
the torque conver does the overdrive when it hits a certain rpm it upshifts to overdrive in torque convertor.
with vein broke it hrows it out of balance causing it to shudder and possibly slip.
I had that same problem a few months ago. I didn't really think anything of it because my car still drove the same and I didn't know it could turn into a big problem. A year ago I had my transmission rebuilt on my cherokee then this year a few weeks after that little light started having problems, my car just stopped moving. I had it towed back to the shop and they needed to replace a bad part on my transmission again. So if you've previously had problems with your transmission I would suggest getting that checked out so you don't get stuck on the side of the road for 4 hours like I did. Sorry if this doesn't help, I'm not exactly a car expert I just have lots of problems with mine.
I would start with replacing your tranny fluid. black is no good. your tranny should hold about 7 qts of fluid. The tranny fluid runs through your radiator to help keep it cool. If your thermostat is stuck closed your eng coolant won't circulate and the coolant will get hotter inside your radiator. thus making your tranny fluid hotter and breaking it down. After time it will turn black from getting too hot. Let your car warm up to normal operating temperture then grab your upper radiator hose. It should be very warm. If not your thermostat is stuck closed.
