96 Tbird OD OFF light does not turn on

I just purchased a used 1996 Thunderbird. I love it!!! However, I have one concern. The first time I hit the TCS the OD OFF light came on and then would not go off. After turning the care off and then back on, it seemed to 'reset' like the manual said it would ie. OD OFF light woul not be lit up. HOWEVER, it has not since come back on no matter when it it the OD Button.

Is this a sign of transmission problems? What should I check before I have it professionally looked at? I can not afford a tranny. Please help!!

When you are driving down the road and you hit the button do you feel it drop out of overdrive?
How many times do you feel a shift from a dead stop?
I bet the button is just bad and the overdrive is working fine except for you can't turn it off.

Or... when you hit the button does it stay out of overdrive? It could be the bulb in the dash.

Thank you for your reply. Yes. I did think of that and when I was driving down the road I noticed two things. It 'seems like' when I am going slow, then accelaerate in one 'click' or push of the button it appears to accelerate quicker. Then after slowing abit, clicking again, it appears that it does not have the same acceleration power. But honestly, I am just not too sure. I live in Providence and getting good speed is for any time period is difficult, even on the the highway.

The Thunderbird is very clean and seems to be well kept. I did call the previous owner and he said he never used the button so would not know. He seems honest, but then again, he sold a car to me. so..... other than this concern, I must say it is one of the best cars I have ever had. This is the first used car I ever boutht, and always wanted a Thunderbird!!! So far I am pleased.

Ok. Additional information now that I think of your question. In attempting to watch the shifts, when it hit 65-70 during acceleration from about 40 mph, it seemed to get heavy and not go any faster for a few seconds, and then kick in again, but did not feel like it was 'slipping' so I feel ok, so far. I am not sure I can tell how many gears it is going though.

If the overdrive is on and you turn it off with the button while cruising then there will be no mistake that something just happened. You will know it even if you don't have a tach. Do it with a steady throttle while you are at a cruising speed after you have gotten above 45mph. The key word here in this case is cruising and not accellerating. Get on the highway and do it while driving the speed limit. If you feel it drop a gear then it is working and the light is out. If you don't feel a change, it is either in overdrive and the button isn't working or it isn't in overdrive and you have another problem. I very, very strongly doubt that this is anything other than a minor electrical problem. I think the button got unpluged somehow.
Have you counted the shifts from a dead stop at normal throttle?

I'll 'bet the farm' that the wires at the base of the shifter are broken. See it time and again. pull the shifter surround off and look at the base of the shifter where they go around it... porbably broken where they move each time you move the shifter.

Ok. I have not had a chance to see how many gears I go through, but will be able to check that on the highway later today.

However, I believe at this point it is something electrical. For a short while the fan for heat did not work (then came back on), then shortly after that, the OD OFF light came on and off when I clicked the button. Unfortunately I was not driving, I was stuck in traffic. Hopefully it will work when I get on the highway.

I thank everybody for thier input. I will post again after I get on the highway.

If overdrive works but the button makes no change while cruising, then usually the switch or wires are broken or loose. If overdrive works and the button makes a change but the light doesn't come on then there is probably a problem with the bulb or the wiring to it.

On the fan part if it was when you first started the car in the morning the climate control waits until the coolant has reached a certain temperature before it will allow the fan to come on so it doesn't blow cold air on you.
