recently my accord had this code p0780- shift malfunction. From some research I figured that since it didnt point specifically to what gear it was shift malfunctioning, and after reset the light and it coming on a week later it wasn't that serious. So I did a couple fluid changes for the tranny, twice so far and it hasnt come on ever since. I heard the malfunction could be all the little particles of transmission getting stuck in the crevices of he tranny leading it to shift incorrectly, and fluid changes should solve this. Tomorrow I'm planning to do another fluid change being 3 total, which is the number reccommended to fully flush out the tranny since it holds about 7-8 quarts, and only 3.1 quarts can be changed out each time unless you flush it completely. This has been a touchy issue. Don't get fucked over by the dealer especially when you don't have waranty, try to do things yourself first. As far as the other code, I never came across that before so I couldnt help you there. Pm if you have further questions. Don't listen to everyone and their stupid reasons, 98-02 tranny's are bad if you dont take care of it, drive hard, never change fluids etc. So if you drive the crap out of your car, then I suggest to get another vehicle cause these trannies are sensitive. Best of luck.
let me kno how it goes....accord manual recommends doing this 3 times, refilling the 4th time and using that as a complete flush, so you'll be looking at 12 bottles of ATF if your is a 6th Gen, I'm at my 3rd change right now, and my what a difference in driving it has made, it shifts earlier, smoother, feels like a brand new tranny to what I had before. I might do it the 4th time as recommended, but I'm waiting to see if the code comes up again which it hasnt thus far, but we'll see....
well in the manual it says drive short distance, and doesnt mention specifically how many miles to drive it....What I did was the first time I changed it, I drove it for like 1k miles LOL, 2nd time was about 600+ miles and third time was around 60 miles or so....I'm not sure If I need to do this a 4th time as recommended in the manual since the shifting and everything has pretty much improved dramitically, but in your case, are you flushing it (4x) or changing it once every 15k miles?
HondaGenome... Did the problem ever come back???.. I am getting the same P0780, and I have done three drian/refill, and not sure how this will work out.. I do have the extended warranty as my Accord LX-V6 is a 2001..
I drive 2002 Honda Accord EX V6 car. It has 111K miles on it and i bought it from a dealer as-is last year.
Yesterday, the TCS and Check Engine light came up together. I stopped the car and restarted the ignition and the TCS light went off but the Check Engine light is still there.
I went to the autozone and the code they mentioned are P0740 and P1676.
What could be the issue and what should i start with?
What do you think it will cost for the repair?
Can I drive the car to work (50 miles a day) until I get time to get it repaired?
It happened y'day when i was returning from work. I stay in Chicago area and sometime last month TCS light stayed on when I switched the car on in early morning cold. But it went off when i restarted the car after some time. But this time, it came up with the check engine light which is still on...
If you have completed the transmission flush (4 changes), try disconnecting the battery for 1 minute to clear all of your codes and see if they repeat. Your accord is known for the aut transmission going out.
