Nobody is going to text you. If you're that impatient, have your car towed to a shop.

The flashing D4 light is telling you that the TCU is reporting an error code. Read the thread at the top of this section that says "read this first" (there's a reason for that...) and you will learn how to read and interpret the error code to determine what the problem is.

Usually, a transmission problem won't make your engine die, though. Is your Check Engine light on as well?

no lights on my guages at all only the flashing D4 light. and sorry i was just figuring someone has had this prob before and could let me know if its safe to drive still cause my girl has to be at work in 30min and we are using my car.

It depends on what the problem is. It may not be serious, or it may result in you damaging your transmission. Pull the code, see what it's saying is wrong, and you'll have a better idea of how serious it is.

It will also flash when there is something wrong with the main relay. Check the main relay.

where is that located? main relay

There is no way to really "check" it tho, u would have to get another one and replace it or repair the current one.

Under the dash, to the left of the steering column. You can get a picture of it on Google (brown and gray box with one plug coming out of it.) However, pull the code first to see if that's the issue. The main relay controls the fuel pump, so assuming that's the problem right off the bat could result in a wild goose chase.
However, the main relay COULD account for the engine cutting out... though normally it won't even start, since the fuel pump wouldn't be working.

Don't make assumptions just yet. Follow the clues that the car is giving you, and only when they turn out to be dead ends, look elsewhere.

sweet thanks =^) like i said i reset the car and now its fine. i will have to check it out more tonight after it cools off cause its 109 here

If the main relay is failing, the insane heat would most certainly do it.

[The_New_Guy]

yeah one of my buddies is gonna come by tonight and help me see if i can find out what it is. thanks again

Thats another reason that the main relay may be the culprit. Its notorious for acting a fool in hot weather.

Uh, yeah I didn't realize u said that already.

[The_New_Guy]

so you think the heat could cause it to short out or even go out? cause its been 100+ for over a month now

Yes there is



Or you could just open it up and see cracked solder joints
