1992 Accord Shudders - DTCs
I have a 1992 Honda Accord LX. It has had several DTCs for the
automatic transmisison set for quite some time (approximately two years for at least 3 of the 4 codes). There didn't seem to be anything wrong with the car, so I didn't worry about it. The D4 light blinks only when the test connector is shorted. I didn't even realize that these were DTCs for the transmission until recently. Recently, the car has started to shudder on accelleration (or under load, like when performing a stall test) between 1500 and 2000 RPM. (It feels like you're going over small ripples/bumps in the road.) It occurs almost exclusively in this RPM range, although it has begun to creep up into higher RPM ranges as the problem has worsened. It is very hard to tell if it is a sputter (engine) or a shudder (transmission). There does not seem to be a sputter in the engine when giving it gas while in park (or reving the engine freely through the specified RPM range). I do not have the service manual for the car (though I have been meaning to get one). The codes are 1, 2, 7, & 8. I do not know if these are long or short blinks because they are all the same duration with the same duration pauses in between. I would guess that they are short, based experience. Can anyone help? I would appreciate any help possible. |

What's the mileage, and how recently have you tried replacing the Honda tranny fluid? 'Curly' |

Also, I guess since I try to take very good care of my vehicles I didn't even think of it being necessary to mention when my last trans fluid change was because I never let it go too long, though I did just check and notice it has been about 24,000 miles since I last changed it. I try to change it every 25,000 miles. (Change it, not flush it). So, as for your other questions, the car has about 174,857 miles on it, and the trans fluid has about 24,000 miles on it. Do you think that's enough miles on the trans fluid for it to start acting up? It's never happened on this car before, even with more miles on the fluid. I was planning to try changing it this weekend anyway. However, here's another question I thought of last night after I already posted my last message: Is it okay to use Mobil Synthetic ATF in this car? The manual says to use Dexron, and the Mobil Synthetic says it's for use in vehicles that require Dexron, so I've been using the Mobil synthetic. Is that a problem with this car for some reason? Oh, and yes, I cleared the DTCs and they came right back (a long time ago). Also, I've already replaced the entire distributor because the bearing wore out and ruined all the contacts (common problem with this car). However that's one of the few aftermarket (remanufactured) parts I have put on the car because it was SO much cheaper than the new Honda part, and I don't know if it will last. When it broke, it never caused any sputters, it just wouldn't start. I thought I'd check on it this weekend also, just to be sure. I would really like to know what the codes mean. Hopefully that covers everything. |

So, as change, as in change, run, change? or just change once? if you change once, you arent getting all the old stuff out of the torque converter. > for your other questions, the car has about 174,857 miles on it, and > the trans fluid has about 24,000 miles on it.

Dexron will destroy your Honda, so the synthetic version of Dexron probably has already. 7 litres of Z1 (drain-n-fill two times) MIGHT get you back in the game, but it's probably damaged beyond hope.

1992 Accord Shudders - DTCs
Thanks for the help guys. One stupid mistake. . .
I've probably been using synthetic for about 60k miles. I didn't see it say temp replacement anywhere in this manual (though I've seen it in others). Argh! I see more and more you shouldn't use anything other than honda products in honda vehicles. I was just using Mobil Sythetic in the engine and trans. Now look where it's got me. While I'm at it, is it safe to use Mobil 1 in the engine? According to that chart it sounds like my A and B solenoids are all bad. However, I'm not having / haven't been having any of those symptoms. Well, I'll try getting Honda fluid back in the trans and see if it's not too late. I may have to drive a couple hours to even get some. I just moved to Ridgecrest, CA and there's no Honda dealer here. Even if it comes back, I wonder how much damage has been done? At least my fluid hasn't ever been dark like the guy with the CRV. Maybe that's good. Is this a case where I should just take it to the dealer and drop the money and have them check it out and possibly do a flush, just to get the rest of the synthetic out, or is it not worth it? |

Bite the bullet, get a proper flush done, and see what happens. In fact, if you notice a distinct improvement with one complete flush, get it done AGAIN to catch the last of the synth. This is NOT the time for half-assed measures. Transmission replacement is horrendously expensive. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

They don't 'flush' honda autoboxes, just drain-n-fill them. Why not order 7 quarts from the dealer and have them put it on the bus? Warm it up, drain it once for 10 minutes, refill with Honda, run it through all the gears for five minutes, repeat. Reset the codes. You'll know soon enough if the codes don't return. If it's WAY better, invest in three or four more quarts and do it again to be sure of good protection. 'Curly' |
