When you're driving and then your drive light starts blinking. can you tell me what's wrong.

Blinking "D" indicates an internal transmission issue, continuing to drive it may cause further , more expensive repairs.

You need to have the car scanned. It is a free service at Autozone,Advance, or Oreilys autoparts. Then the clerk can tell you some of the possible parts you need. If you get the Code numbers, we can tell you what the onboard computer is telling you.

Be careful if it is a Code 401, for that engine the scan can be wrong. If 401 comes up, it can be a clogged EGR port in the Intake manifold.

if it is blinking do not drive anywhere. if it is not blinking drive to your nearest Autozone and they will tell you what is wrong.

With the light flashing ,codes are stored in the transmission control module . Have the codes check an this will tell you whats wrong . Probably a sensor or shift solenoid or line pressure solenoid .

You need to extract any code(s) that had tripped the tranny computer. Here, you can find what is actually going on with the transmission. The blinking OD lamp is telling you something is wrong with the transmission.

Hope this helped.

you have a severe missfire thats why the light is blinking
the smoke and sound were the cat converter[s] glowing red hot from the missfire
dont drive it untill the missfire is fixed or youll ruin the cats[if not already] plus a good chance of fire exists

you have a transmission fault the D4 light blinks to tell you that there is a transmission problem when the light is blinking the transmission computer put the transmission into limp home mode so it will not shift normally and you should try not to drive it very far when it gets to this stage you need to have the transmission codes check to pin point the problem

IM NOT SURE BUT THAT MEANS SOMETHINGS WRONG DRIVING IT COULD DEPLOY AND HURT OR KILL SOMEONE I WOULDNT DRIVE IT TILL I GOT IT FIXED

u need to have the codes retrieved and take it from there, there are specific codes that need to be troubleshooted in order to diagnose it correctly...

you have a bad srs relay, take it to autozone and tell them you want a trouble code done, it is free, it will tell them what it needs.
