Transmission problems

Okay I have a 2004 accord v6 automatic transmission. Just the other day when the car was going to first to second gear instead of switching it the rpms just started shooting up and didn't want to go anywhere as if it was in neutral. When I turn it of and restart it my car works for like 10 mins. Its taking time for reverse kick in and taking a little longer for drive to kick in like. I checked the transmission fluid its a little dark but not to bad. Well hope y'all could help me thanks

^Could be , but the way you are describing things sounds more like a total loss of fluid pressure intermittenly.

How many miles are on the car? Did your car ever get the 2nd gear oil jet kit put on? There was a TSB for that and if they never did that then you can use that to your advantage. GL.

The oil jet kit was a worthless band-aid that didn't work. Transmissions still failed. Take the car to Honda, they need to replicate the problem. If you are lucky, they will goodwill the new transmission and torque converter, if you don't have an extended warranty.

Your transmission is shot, mine did the same thing.

Okay my transmission is shot but it only works for a little while. So what was wrong with yours. Was it the gears was it the solenoid or torque converter.

i bought my car from a used dealership a few years back with like 40k on the dash, started having transmission problems about 6k miles later...felt laggy between shifts and what now..they checked it and said it was fine...then 1k miles later the trans is completely stuck in 1st gear...so i bring it to a local honda dealership. tells me that my solenoids are shot according to their computer...okay they replace them and it doesnt solve the problem...offers to replace trans and labor for $4500 i said hell no...then comes back 5 mins later and says okay we can do honda goodwill and it will only be $2200 for trans and install..so i said i dont have the money...comes back and says dont worry about it we will take care of it and they replaced the transmission for free..

Okay went to Honda they were trying to charge me right at 5000 new 3900 used. Crazy I asked him if that's the lowest he could go. Said American honda only said 10% off. So he didn't want to work anything out any lower. he said internal failure you need another tranny. The mechanic walked me out and I asked him what exactly was worng. He told me the clutch worn out. The reason was because of aggressive driving makes since. So is the any over haul kit out there or anything like that

I would also go to another dealer and see what they can do. Maybe they can do what they did for sickv6. I wouldn't just give up yet. My buddy has a 02 accord and his tranny went and he was out of warranty. Car only had 78k on it and the dealer just made him pay $500 total for it. He went to 3 different dealers and then finally got a good price. Good luck with everything.

Yes they were all honda dealerships. They are the only ones who can help you with the discount on the trans. Its a known problem on our cars.

Instead of starting a new thread I will continue on with this one.

For anyone that has any 3rd gear slipping problem there are now many fixes to try before giving up on the transmission. Most of them do not cost much and are not that hard to try out.

1. Change your 3rd and 4th gear shift pressure sensors. (about $80 internet price for both)
2. Change your transmission filter. (about $11 internet price)
3. Change your transmission fluid doing a 3x3 (3 quarts drain and fill 3 separate times)
4. Check your shift solenoid filters to make sure they are not plugged.

If that does not cure the 3rd gear slipping problem you can move on to the more controversial fixes below:

5. Adjust your shift solenoids using a special tool made by Sonnax part number 88950-T.
6. Change to a non-FM (friction modifier) type transmission fluid such as Redline Racing ATF or Redline Lightweight Racing ATF.

Number 5 and 6 will also let you adjust the transmission for a more sport oriented feel with quicker shifts.

My Accord that has 183,000 miles on it and was no longer able to shift into third gear but with all of steps taken above it now shifts better then when the car was new. A much more Sport oriented feel with much shorter snappier shifts without the lag in-between shifts. I wish it had shifted this way for the first 182,000 miles. Although it may be dead by next week, who knows.

Thanks for the post Jaster, googling for the stuff I found lots of (at least for me) new stuff about automatics problems.
It looks like the pressure switches are the root cause of all the problems, it works like this:

1. the switches measure the pressure fall/rise of the fluid during a clutch dis/engagement, ECU uses the input to learn the ammount of the fluid/time required for the dis/engagement
2. the switches wear faster than they are supposed to (probably due to heat) and start to feed the ECU with inaccurate input
3. ECU attepms to time the disengagement of the gear it is shifting from and and engagement of the gear it is shifting in so they exactly match, but fooled by the broken switches it misstimes and causes the clutches to slip
4. unlike MT clutch the clutches are not designed to withstand slipping, their function is more similar to synchros than to a clutch; few seconds of sliping under load destroys the clutch completely (damaging is the heat generated, not the friction itself as far as I can tell)
5. the friction modifiers in the Honda ATF Z1 make the slip last longer

So IMHO all the fix steps from Jasters post including the 5. and 6. should be done, and not just as a fix but also as a preventive measure.

As to which fluid to use, Redline D4 ATF seems to be the best, both as to what people report and because of its formulation. It makes shifting under light throttle as plush as the Honda ATF Z1, and under high throttle it shifts smoother and faster at the same time - the friction modifiers in the Z1 cause the clutches to keep slipping during engagement and then suddenly engage, resulting in a long bumpy shift, while the dynamic viscosity of the D4 makes the engagement linear and short.

Hi guys I'm new. I just got my 05 accord cpe v6. My tranny is not slipping or atleast I can tell yet but basically it won't hurt my auto tranny if I did a flush and put the Redline D4 ATF? Or is that just a solution to fix the tranny slipping? ? Sorry to re-ask the questions. Thanks.

See the thread on acurazine. There are some guys running non-FM fluids in TL's with promising results. Accord *maybe* needs some FM in the fluid (ie the D4) to prevent shudder as unlike the TL it doesn't close throttle during the shift, but thats just a guess. I'm myself leaning to try the Lightwheight Racing and see how it works, I did D&R with Z1 (was using DEXRONIII before) shortly before I found about The non-FM fluids and for the first time that I own the car I experinced a slip during shift, two times so far, the revs rised for a fraction of second going 2-3.

for 6th gen they both are 28600-P7Z-003
on www.hondaautomotiveparts.com they are under "AT SENSOR - SOLENOID", the part is "SWITCH ASSY., OIL PRESSURE"

Just replaced mine, the one under battery is easy, the second is hidden like a treasure, in front of the distributor, on top of the tranny, had to use long tubular socket wrench on that one.

I had a chance for only a short test so far and the car was still warmed up, the shifting is less noticeable and faster, at idle standing still on the brake and shifting, the kick is greatly reduced, bump-shift 3->4 under light-to-none throttle is almost completely gone (very minor bump is still there if you watch for it carefully tho), WOT shifting seems the same (differences if any are probably hidden in the kick due to stiff mounts), and isn't erratic, but the erratic shifts under throttle were happening only occasionally for me, will see in longer run if that is fixed.

On cold starts I used to get a metallic clunk going to reverse (sometimes even few seconds after the shift itself, when I was already backing), and the kick going to drive/reverse was pretty strong, I'm gonna test that when the car cools down.

I think you may have typed that a little to quick. Of course they need to be different part numbers for the 2 shift pressure sensors.

on the 6th gen they are really both the same part number, unless there is mistake in this diagram:
http://www.hondaautomotiveparts.com/...ENOID+%28V6%29
28600-P7Z-003 014 002 SWITCH ASSY., OIL PRESSURE (TEXAS INSTRUMENTS)

the 002 is required quantity

28600-P7Z-003 is 33psi, 28600-P7W-003 is 27psi, and the switches I took out were both the same part (slightly different than the new). The following post on acurazine suggests 28600-P7Z-003/28600-P7W-003 combo from year 2000 onwards, the www.hondaautotiveparts.com displays 2x 28600-P7Z-003 for all 6th gens 1998-2002

My Bad. I had never noticed on a 6th Generation that they do use the same pressure sensor for both.
