D4 Light flashes
hey, can anyone help me? i have a 98 integra rs (automatic), anyhow, my D4 light flashes all the time, adn my check engine light is on. Has anyone ever encountered this before? It's a little rough sometimes when its changing gears, and my gas mileage is terrible. Any help would be appreciated.

I think that it is a transmission code. I remember reading in the manual that it is a problem with the transmission. There is a symptoms chart to go with it, certain conditions with either the light flashing or off. Is the tranny acting weird, not downshifting, slow upshifts, hunting between gears, or no overdrive?

i have the EXACT same problem. my D4 light flashes but the check engine dont come on. the check engine comes on when the sspeedo dont work. but thats another problem altogether and should go away when i swap the engine. anyhow i think that its the transmission and sooner or later it will start to slip. like i know my tranny is fcucked right now whenever i make sharp turns it goes up to high rpms. and i know there is something wrong but i dont care to fix it...just because this tranny and engine is gone next season. but other then that get your tranny checked out...it will get worse

Well I took my car to Acura last night to get them to diagnose the problem and they said I need a whole new transmission! I just don't believe it, this light in my car has been on for 2 years, and I haven't had a problem, how could I need a new tranny?? The codes they got from my car were..
P0700 - Automatic transmission control
P0715 - Problem in mainshaft speed sensor circuit
P0730 - Problem in shift control system
Don't you think with all those problems, that I would notice something wrong with the car??

Sometimes replacing just one sensor would solve all the other problems.
Since i see this being a common problem, I’m sure someone will reply you with a better answer and solution.
As for the Acura killer ship....they just want to make the most out of you.

ok, do me a favor...
Check the transmission fluid level. If you do not know how to do it (not trying to be sexist here....my sister doesn’t know either), have your dad, bf, uncle, friend etc check it.
It is also mentioned in the car manual how to check it.
report back with color of the fluid..it it reddish pink or brownish?
any burnt smell?
How many km do you have on your car?

or her b/f's brother can check it 
...Sarah Call me when you get a chance or just pass by the house
she took it to acura and they said she needed a new transmission...i think she has just over 100,000 km on her car.

im thinking its the fluid..."ALWAYS use honda ATF fluid, costs little more..but in the long run its worth it, " or its the speed sensor.
Buff4Prez, do let us know what was the issue!

Haha you sound just like Mike, he said do a 5 speed swap too haha.
I looked at my tranny fluid, its a redish colour, no weird smells or anything.
I have called Acura's customer care, and if I can provide all my maintenance receipts fro my car, they will consider replacing my tranny for me since I still have low k's on my car. I let you know what happens with them.

Let us know how it goes with the killer ship.
Also, my experience tells me that Honda and Acura have a very picky transmission, if you don’t use the recommended fluid...it wrecks it...oil seals get eaten up, build up of sludge, improper shifting etc. All this info was gathered from other sites such as TI (before I even knew about TI), when my friend was having a transmission problem. It wasn’t the D4 light flashing but sometimes it would shift improperly, late ----, would not down shift etc. When we switched to ATF, it solved the problem 100%.
If you planning to buy the ATF fluid, get it from Honda its cheaper…and it’s the same it you would get from Acura (same bottle, packaging name etc). I guess when you walk into the Acura killership all they hear is chaaachinngg!

hey Acura girl,
i had msged someoen with your problem, he was having the same issue.."D4 light flashing" ..this is what i got....
" I dried the ECU and the light stopped flashing after that, the code that I was getting was an ecu code so that fixed it. Your problem might be different"
I think reseting the ECU after u do the flush would be a good idea!

Ok, so I have talked to Acura and they are not gonna help me out with this because I can not provide them a receipt of having my tranny flushed at 48000k's. So I guess I will have to start looking for a new tranny, but I might just try the speed sensor first.

Hello Acuragirl,
Getting the tranny flushed is a good idea. Please make sure you get the Honda ATF fluid...if you don’t get this, it is no use doing the flush. 278$ for the speed sensor seems to be a little steep. Have you shopped around for this?
Also, in your next post, pls explain a little more on what exactly happens with your tranny. Is it just the D4 light? Does it shift irregular? Do you hear any grinding or squeaking noises?
Resetting the ECU, it is very simple...however i am not sure if you are the DIY kind of person who doesn’t mind getting their hands dirty once in a while. If so, post back and I shall give you step by step instructions.

As for resetting the ECU, I probably wont do it myself, but if you can give me instructions, I can get someone to do it for me.

acuragirl..., I know u wanted to do this on the weekend…so here is a link on how to reset the ecu ....LINK . I got this from TI. Keep me posted on how it turns out!
If I were you...I would just drive the car until the trany dies...cause fixing it is as costly as buying a new transmission. Talking about transmissions ... I found out that "Mr. Transmission " do a free check up. Not sure how good they are though!

Now with these engine codes/transmission codes, they give you a pretty good idea of what's happening. I poked around on the net for your problem and it could possibly be a problem with the TCM (transmission control module). Definitely change your transmission fluid though as the first step, it's cheap and it's long overdue. If you continue having problems passed that, maybe try swapping the TCM with a known good one
