SOURCE: Gear Position light D4 is always flashing irrespective of gear.

This issue is caused by a transmission fault or malfunction, most likely a shift solenoid in the trans has failed or the trans control module has a problem, the trans can be tested for codes that will show what circuit or component of the trans controls is causing the light to stay blinking, have it tested.

SOURCE: car will not start when hot, D4 light is flashing, car will start

I had a '91 Accord. When the car would get hot, i.e., sitting closed up in the hot sun, the car would not start. Not even turn over. I don't know what the D4 light is. I called John Eagle in Houston where I bought it brand new. The service supervisor said it was probably the main fuel relay. I think that's what he called it (it's been a few years). This relay shuts the gasoline off to the engine when the car gets too hot. It is a safey thing so that the car won't catch on fire, like in the case of an accident. He said to open all the doors and raise the hood so the car can cool off. Sure enough, after about 15 minutes or so, the car would start right up. If I remember correctly, I think the relay is located under the carpet on/near the firewall on the driver's side. Seems like the Honda OEM part was about $80.00. Don't know if this helps or not, but I thought I would throw in my two cent's. Good luck.

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

SOURCE: 92 Accord Automatic shifting

Has anyone change the transmission fluid and used anything other than Honda ATF-Z1. If so, have the fluid/filter changed in this car and use only Honda Fluid. This is the only fluid that you can use in a Honda. Even if you have used the correct fluid an fluid/filter change may help. If that is not the case then I suggest you seek out a trusted professional.

Transmission gears or the bearings or the throws are worn - so things do not stay where they are supposed to & this cause the tranny to pop out of gear.

My car just losing power its a automatic goes from 4th gear to 1st rev away up can any one let me know whats wrong its a daihatsu yrv turbo

That looks like a burnt out clutches.
Check the fluid in our transmission, if it is in minimum level, add up to the max if needed, smell the fluid if it smell like burned oil that means clutches gave away and needed replacement.
You have to bring your car to the nearest garage to assess the damage to your transmission and ask them how much your gonna spend for the repair.
You have a choice for a rebuilt, came from junkyard, and do a total repair/overhaul for your transmission. Whichever that makes you save some money.

Hope that helps!

Will not start and noticed that when you attempt to start, both the park like is on and D4(drive),D4 light goes off and still will not start.

if the D4 is drive like as in P R N (D) D 1 then the car thinks you are in gear the netrual safty switch is not working try shifting the shifter the car will only start in park or nutral if you get it to light up the P or N be carefull KEEP YOUR FOOT ON THE BREAK when you try to start the car cause the car maybe still in gear if it is malfuntioning

It sounds like you have one of a couple problems. First, for the D4 light to be on and flashing, there is a problem the TCM (transmission control module) is seeing. If this is a V6, these transmissions are notorious for having problems internally, and need to be rebuilt at a transmission shop, or replaced. There is also a chance that either the third or fourth gear pressure switches have gone bad they will be the black and brown switches bolted to the top of the transmission. These can also cause this light flashing to occur. I dont understand the rest of your post. If you could clarify what you mean i could try to answer you question a little better

If it feels like you only have 2 gears, and 1st is gone, then it sounds like the transmission computer needs to be replaced. Very easy self done job.
