My overdrive light is flashing indicating the overdrive is off
My 2002 Explorer has always been in overdrive since I bought it, recently the light started flashing that it is out and I have no idea why? I need to find out how to get it back in overdrive? It is an automatic and now when I need to excelerate quickly it revs up and has a delay.

This could mean there is a problem with the transmission,but most times when OD light is flashing it is because the wiring to the OD switch is broken.
is the OD switch on the end of the gear shift lever ?
or does your vehicle have the shifter on console between seats ?

Overdrive (O/D) Off
The O/D OFF indicator illuminates when the transmission is locked out of O/D. This dual function indicator will also flash off and on if a transmission malfunction is detected.
This means there is probably a DTC - diagnostic trouble code stored in the transmission control module ! You'll need to take it to a repair shop !
The overdrive light also serves as the "check engine" light but for the transmission. If its flashing it means the computer recognizes a problem with the transmission or its electronics. If the engine was just replaced, they probably forgot to plug something in, or some wiring got damaged in the engine swap. It can be scanned with a scan tool for a code and the code will indicate what circuit is at fault.
You should have the computer self tested by someone with a scan tool. The flashing overdrive light indicates a concern with the transmission. Self testing the computer should produce a fault code and give you some idea of what is wrong.
If your overdrive off light keeps flashing this indicates an electrical or mechanical fault has occurred with your transmission and a diagnostic code has been stored in your trucks on board computer. The stored codes can be read by diagnostic scanner and will aid in making a diagnosis of the problem that is occurring.
the OD light flashing indicates that the transmission control module has observed a fault. Take the car to a local aftermarket parts place and get the codes pulled (typically free) this will send you in the right direction regarding a repair.
it is probably the vehicle speed sensor. Tells computer how fast the car is going so it will shift at proper time. A tech with a scan tool can run the EEC test and read the codes and tell you if it's the speed sensor. easy repair. Buy speed sensor on Ebay
The O/D light flashing is an indication of a transmission electrical fault. The powertrain control module (PCM) monitors the electronic sensors and actuators on the engine and PCM. If it finds a fault on these circuits, it will alert the driver. Since the O/D light is flashing, the fault is specific to the transmission. You'll will need to have the codes checked in the PCM before any repairs are attempted.
