1995 Ford Thunderbird

It means your ECM has detected a problem with the transmission. Many trans faults can be remedied harmlessly if done quickly. Of course, there are some problems which call for an immediate rebuild A dealer or well equipped trans shop should be your next stop to detertmine the fault code and whether failure is imminent. Also, the light should be flashing in a pattern such that you can count the flashes and arrive at a digital code depending on your vehicle make/model/year. etc which you did not provide. Someone here may be able to interpret the code for you if that is the case. It is also possible that more than one code is stored.

Approximately 8/24/03 12:58, Jess uttered for posterity:

If the engine RPM stays unchanged, meaning that it isn't really going in and out of O/D, the light means you need to have your transmission control checked... is a fault indicator.

The flashing light means the PCM has detected a fault inthe transmission. You need to get the codes checked out.
