Overdrive Light Blinking

Any idea why my overlight drive would be blinking. The engine light is also on. I do not have the tool to get the codes so any advice would be helpful. Transmission? That's my guess. Oh yeah, The car is a:

2003 Crown Victoria P71 Police interceptor.

Get the codes read.
The CEL can be read at any parts store that does it, the trans code most likely has to be read elsewhere but you can ask at the parts store.

I have the same problem but I burnt some wires in my trunk when my system caught on fire but I checked the wires and they were ok but I got my tranny rebuilt 2 months ago because of the OD light flashing and its still doin it I was wondering if my problem would b electrical before I take my car back to the shop....my car starts but runs like it has no power...97 Crown Vic

+ 1 on getting the codes
Looking on crownvic.net some of the newer models like your 2003 will show a CEL if they have gone into limp mode. This would be the case if your tranny is acting up. Also looking at crownvic.net it looks like the most common issue with the overdrive is the solenoid going bad not actually the whole tranny.

Also there are some nice bluetooth scanners available on the web for pretty good prices I picked up an ELM327 v1.5 and it works great, newegg.com has them for around 20 bucks. You do have to have a laptop or Android phone though as the Apple App store doesn't have a compatible app. The Android App Torque Pro runs 4.99 and pulls all the standard data as well as all measuring points in real time.

SamTi44 did you get the computer reset after the rebuilt tranny? If not hit up your local Autozone or O'Rielly and reset the ECU to see if that clears up your light issue. Also if your ECU is still showing the tranny issues it may be keeping the car in limp mode killing your power.

Im not sure if it was reset but I will try it..Thanks
