Another illiterate mechanic on the loose, dude get a scanner first, it's cheap less than 4k .i made a similar mistake and almost paid dearly for it.i wonder why all these illiterate mechanics just can't buy and use a scanner to first diagnose current fault in modern cars with computer.by the way the ATF you used is wrong.to avoid expensive repairs drain it and refill with recommended fluiud.

Mmgboji:
1. Change your rewire or you will be on your way to changing your transmission (gearbox).
2. Drain that Oando fluid and replace with recommended fluid.
3. Scan the car.
4. Follow the result of the scan for a straight forward fix.
5. Nothing is wrong with your ECU.

Stubborn82:
Thank you everyone for your advice, I really appreciate.

I later scanned the car as it was suggested here, the scan pointed to gear selector switch (picture attached).
Though, the rewire was not happy with me when I told him that I want the car to be scanned because he felt, I didn't trust him and I made him look as if he doesn't know his job.
When the scan guy tell us the fault, my rewire allowed the guy to do all he could and still come back to point of changing the ecu, we changed the selector switch the problem is still the same, because the ecu is not passing circuit data correctly, meanwhile the scan guy give me a trick to use if I don't want the blinking D light, he said that if I don't have the money for ecu, I should put the gear to neutral first and start the car, and behold the light stop blinking, but once I put the car to park and shift gear the lights would blinking again. But I think that's risky for me, it is better to change the ecu.

If your car is not having any drivability issues please don't change the ECU. Don't go and inherit another bigger problem. You did not share the codes here. What we need is just the code. Go and buy an obd Bluetooth scanner and be doing it yourself

Well first things first, for the honda accord EOD, dextron III transmission oil can be used temporarily, its in the car manual. However a one drain doesn't remove most of the fluid. Drain again and use honda dw1.

Go to where they use a more sophisticated and expensive scan tool and scan your car. These expensive scan tools can scan each component (transmission, srs etc) of the car.

What were the codes you got when you scanned, P0750 indicates a gear selector switch issue.

Look for a honda gear specialist to guide you not any mechanic.

Lastly do your research, there are tons of videos on YouTube, research the codes from your car scan or the issue you are experiencing on YouTube specifically for your car type, you would see others may have documented same issues you have.

Good day good people

I have come again o

Last month my car eod was blinking D light, as I was driving home, so when I got home I park, they I started seeking for advice here and some other channels.



Some advice me to check the fluid level, I checked the next morning before starting the car, true it was below the low point.



So I decided not to drive it until I got another fluid, but I do start it to warm every two days, but I later begin to see, park, at same time with reverse light and D light blinking while the car is in park.



I took it to mechanic, we remove the fluid and put oando dexron 3, but these light are still showing, I was told it might be pressure switch, we changed it, we clean all the sensors that are cleanable, the electric rewire trace eventing traceable but yet these light remain.



So he remove my car ECU/brainbox and put another one from another eod, and immediately all the lights clear off, the rewire told me that my ecu got problems that I should change it.



But I told him to wait, I want hear from an expert on nairaland on what they will advice.



Should I change the brainbox or is there any possible way out.



Though the gear is driving well with those light on and D blinking.

This is a first hand info from me< i have used the car a couple of years ago and i experience this issue. It will only take you to clean your transmission filter and change the oil if due for change. The problem will be solved.

Stubborn82:


Thanks for your response sir.
Please where is the transmission filter located, is it inside the gear or where.

As is it now, we have changed different brainbox but the conditions still the same, I took it to another person that many refer as expert, he told me that the problem is brainbox, I told him that we have try different brainbox but didn't solve the problem then he told me that maybe we didn't try the brainbox that is actually fit the model, that I should let him go and find the right brainbox.

The transmission has not been opened before and I don't want situation where they will damage the transmission for me.

what actually lead to me knowning about the filter was after buying a different gear box and the problem remained on the car. Called back the gear seller in annoyance he sold me a bad gear that the car is doing exactly like the old gear.
The mechanic has already sold the old gear to Aboki as scrap. He then sent me a guy to check the gear and he told me my gear might be good after all that the filter could be the issue, he then charged me again but I made sure I studied exact what he did which the mechanic never was aware of while we struggle with the old gear.

The filter in a very small on the size of a finger tips been hold by a mere random nut below the battery stand. God cleaned with carbrator cleaner and the problem solved.
After over two years of use of the new gear, there appears the problem again, the first I did was to instruct mechanic to do the cleaning first and behold the prom blue disappeared till it was sold a year later.
Find the nut under the battery stand.

Yes there is a filter underneath this. Very small finger tip size. That is the culprit .
