Earlier this year I tried fixing my slight 2nd to 3rd slip by cleaning the solenoid, but it didn't work. Now that it is colder out, I've noticed another problem that only occurs until the car warms up (about a mile of driving).
When the car is cold and I come to a complete stop, it hangs in neutral for about 2-3 seconds and then slams hard into first gear. Feels like I hit something or something hit me. Similar to my slipping, once the car has gotten to operating temperature, the problem completely goes away.
I've done some googling and found a few forums for other cars that say it could be related to the torque converter. Others (mostly BMW) say it could be fixed with a TCU software update. Could it be either of those? I'm planning on having to get my transmission rebuilt in the spring, assuming it makes it that long, but is there anything I can do until I reach that last resort? I only just hit 77k miles. It drove just fine when it was 85 degrees this summer after I bought it, but colder weather has begun to unveil a slew of transmission problems.
That description doesn't sound good for sure. How does the trans fluid look? Sounds to me like it is on its way out unfortunately.
Doesn't sound like having it rebuilt is the best idea as the 06/07 accord AV6 trans has been proving a good replacement
we have a problem with sludge and crud in the torque convertor that slings outward and clogs the filter screens = no pressure to shift
Letting car sit parked 15-30 minutes restores temporarily- the trans ability to operate
Try using SS mode, used higher line pressure- any better??
Are you on the new DW-1 Honda atf? it helps - better fluid than the old spec which is gone forever
As the car is new to you, do you have any maintenance history?
ckd for trans being a warranty replacement?
Ckd the front and passenger side motor mounts? 75kmiles you are right on schedule for a front failure, causes mystery vac leak and rough shifting
we need you to get under the car and ck for fluid
I have seen cars blow out a main seal and make it home, a block away it pukes out the fluid- you stop the car and next time it wont go!
Any news on this? I am having a similar issue as the OP but it's not a hard drop it just shifts as if it was in neutral back into gear like nothing happened. And as he said it only happens when it is cold, no issues at all once warm. Haven't done any solenoid cleaning as I have an 02-S and I'm still looking around to see which one to clean or all... I just had the fluid changed by a Honda dealer but I am starting to think (hoping*) it's an issue with old cv/axle assemblies as the car has some vibration under acceleration. If that's not it I just have a boat load of issues to fix.
All 3.1 quarts. The transmission was doing the same thing prior to fluid change. Mechanic said it was on its way out but also told me I had to do the timing belt, rear main, and oil pump seal all at once.

One 3 qt change is only approx 1/4 of what the trans holds. Most usually do a 3qt change 3 times over with some driving in between changes. That will get a majority of the old fluid out and replaced with new.
I wouldn't do the timing belt etc until you figure out if the trans is on its way out or not

I'm going to put her up on stands tomorrow and check her out. I'll know more then.
Oops, I forgot I posted this because I've been waiting for warmer weather to really start investigating since it's been way too cold to work on it outside.
I have no maintenance history on it other than the fact that it was originally a lease. I have absolutely no leaking of any fluids at the moment (knock on wood).
I did a 3x3 fluid change with the new Honda DW-1 directly from a dealership between August and Septmeber. I drove about 2-3 weeks in between. The first 2 drains were pretty dark, and the third was slightly better. I'm wondering if another 3x3 would do me any good. It's still pretty dark even after the first time, and I think another 3x3 would get it all back to a nice clean red. Maybe it's just really dirty in there?
Now that I've driven it in the winter, I can say that it would hang in neutral for 3-4 seconds sometimes. Long enough for people at 4-way stops to start to get frustrated when I didn't move right away. But now that it's getting warmer again, it's getting less and less pronounced.
I have a surge between 2nd and 3rd that isn't horrible but it is noticeable. I can get it to shift smoother if I use Sport Shift and let it get past to 4,000 rpm first. I'm guessing these things are related. But as I mentioned earlier, I did clean my shift solenoid, but I didn't apply current to it to test it unfortunately.
^ The 3x3 should come out Brand New ATF at the third change.. If don't then your trans is dirty asf.. Go a 2x3 until the ATF starts to come out almost brand new.
Isn't the transmission screen on the 99 internal? If I get to that point, I think I might as well get the whole transmission out and have it cleaned up and rebuilt. I'll try the 2x3s though and see if that does anything.
I still get the slight surge from 2nd to 3rd, but the hard drop into first at stops is pretty much gone now that the temperature is in the 50s here. Hoping that eventually getting the fluid clean will help.
Based on the transmission diagrams I've seen, it doesn't look like it. Is there any way to get to the screen to clean it without taking the whole thing out?
I guess that makes my life easier in a way, as I'll just have to do the drain/fills (but makes my life harder because I can't clean the inside properly).
according to the gen1 thread diy linked above, it goes to 98,but 99 was still the 4 speed
Look at the diy then look under your car- a match?
In that case the bottom cover does come off the trans and a replaceable screen filter is right there, similar to older American cars
One of our acura dealers/vendors can hook you up with the correct parts and number of qts of dw-1 fluid
Option: a can of seafoam Trans Tune driven for a week and drained-new filter- fresh fluid, will do wonders at getting the old dark sludge out of the oil passages and ports
If you suspect clogged filter now, install a fresh one and then add new fluid and seafoam, let the new filter catch the crud for 2 weeks and do a full change on all parts and fluid
Honda makes a special Gasket Cinch product that works awesome on paper and fibre gaskets, holds in place, seals perfect and doesn't ever dry, so when you need to remove later...!
OP, you should click on the link above. Another guy had tranny problems with his 1999 4 speed. He fixed it by changing all the electronics on his tranny. Its worth a look.
Did a 2x3 trans fluid change last week. It wasn't even close to red. Considering I already did a 2x3 or possibly a 3x3 (can't remember anymore) less than a year ago, that's not good. Not sure if I want to sink another hundred bucks into more fluid at this point if it's never going to get red. Anyway, just updating. Here's a pic of the fluid from the first drain last weekend:
And here's the magnet that had just as much metal on it as the first time I drained last year:
It's almost as if I dreamed the first fluid drain/flush! Déjà vu.

If you're looking to fix the surge in 2nd to 3rd; 1 st gear drop you need to replace...
1. Shift control solenoid valve C.
2. 2nd clutch pressure switch.
3. 3rd clutch pressure switch.
It's hard to say if that's a lot of material on your drain plug because the drain plug is apparently doing it's job - keeping that stuff from circulating through your trans.
The color appears the same as mine (after ~50K miles since the previous change, which was a trans rebuild) and I'm not having any serious transmission issues. I wouldn't break my back changing it until it turns red. Just do a 1x3 every 2nd oil change and squirrel away ~$50-$100 per month into savings for a new AV6 if/when yours dies.
