Went to dealer Sat. to get tranny fluid. Bought 4 Qts. , thank god I did. Book & service guy said "3.2 quarts needed"! When I got home & drained it out, it ends up being 4.3 Qts?? Because of extra cooler for tranny? Any Ideas? I had enough b/c I had a quart of Syn. ATF from Valvoline in cabinet. Just curious of amount it drained. Anyone know? Thanks LP
PS. If this is in the wrong place moderators, sorry. |

I used 4.5 quarts per flush ( no cooler) when I did my triple flush. And boy did it need it!!!! only 15K miles |

I would be acreful about mixing ATF in a Honda/Acura trans.
I know the Syn will mix with anything, and is consided to be higher "quality".
The issues is that has different specifications than the Honda fluid, and may have adverse effects over the life of the Trans. |

.
Those that have performed the transmission drain indicate that 4 quarts is normal. Posting on the older threads indicated that the owners manual and service manual indicate 4 quarts per drain.
However, I just checked my owners manual and you are correct, it does indicate 3.2 quarts on the change. From others posting it appears to be about a 1 quart discrepancy.
Good question for the forum Lrpba300.:29: |

Thank you BaldEagle! I was beginning to wonder there! I thought ya was against me :D I just wanted to know what the deal is.

It was to late on Sat. night to get to the dealer & I had to drive the vehicle. I figured 1 qt. of syn. ATF would be ok till I change it next time. :rolleyes: |

The crux of the issue. Do we know for a fact that synthetic ATF is better for Honda/Acura transmissions than Honda's own Z1 fluid? No, we do not.
Do we know for a fact that Z1 might not be a synthetic or a blend?
No, we do not.
So why change to something different, and if the transmission does have a latent weakness, at best just delay the outcome?
I plan to follow Acura recommenations for 'severe' service, keep my warranty intact, and when the time comes extend that warranty. Plus, do a flush at an Acura dealer when the time comes. Other than that, drive, drive, drive! |

| DaleB, that quote was from N_Jay, not me. If you read the original post, I said I had to use ONE QUART of Syn. ATF fluid b/c I didn't have enough. I feel it will be ok to add 1 qt. till I can change it later. I still want to know why the book says 3.2 qts., but when I drained the ATF fluid, it was more like 4.3 qts? It seems to shift quite smooth again, now that I've driven it for a few days. |

I realize that, I just jumped in as an excuse to raise my number of posts. I'm so shameless.....:bonk: |

| Anyone else change their own transmission fluid and get by with using only 3.2 quarts, or did it take over 4. :confused: :confused: |

| I checked the 01 svc manual earlier today. There are numerous references to tranny fluid capacity/change. Only one says 3.2; the balance indicate 4. Majority rules so it must be 4+. |

Then owners manual is wrong. It indicated 3.2 quarts. |

Hey, I'm just statin' da facs! Gotta pick a number, might as well pick the one that shows up with 4x the frequency, right? Besides, the tranny takes whatever it takes to get it to the 'fill' line on the dipstick. My intent is to buy 4 quarts. Better to have a little left over (won't, though, based on everyone else's experience) than having to hitch a ride to the dealer for another quart :D |

Of course, we are just talking PARTIAL CHANGE when we do the 3.8-4.2 quart thing....
keep in mind that even with the severe service, doing the partial drain and fill, you will be running on approx 1.5 Quarts of ORIGINAL Fluid at 90,000 miles!!!! (That's if I did the math right..)
I plan on doing full flushes.

Ard, we all love ya, but can you run us through the math that you used to determine this?:D |

I'll try...
figure 8.66 qt for the overall capacity.
Then 3.8 is what you get when your drain.
Therefore, after one partial drain and fill you have this much OLD oil:
1-3.8/8.66= 1-43.9% = 56.1%
So, after one service 56% of the total fluid has not been changed, or is "old"
(The severe service interval is 30k.)
So from 30 to 60 you have 56.1% old or 4.86 qts.
Then at 60k you change part of it again.
56.1% x 56.1% = 31.4%
31.4% of 8.66 capacity is 2.72 qt
Then at 90k you change some again
31.4% x 56.1% = 17.6%
17.6% of 8.66 qts is 1.5Qts
Also, keep in mind that there is some fluid that has 60k on it (approx 1.2 qts) and some fluid that has 30k on it (2.14qts) plus, of course the 3.8 you just added...
There's a couple of ways to skin this cat.. You can also just figure out what happens at each change:
30k 4.86 original and 3.8 new
60k 4.86x56.1% = 2.72 original, 3.8x56.1%= 2.14 ('30k') and 3.8 new
90k 2.72 x 56.1%= 1.52qt original, 3.8 new, 2.14x56.1%=1.2qt ('60k') and 2.14 '30k'
As common sense would indicate, there is a mixture of differnet proportions of age oil, and each proprotion is reduced by the same amount with each change...
Anybody still think the partial drain is adequate or advisable? And to think there is actual discussion of the impact of a quart of synthetic versus factory fluid to top off a refill! 18% of the transfluid at 119k miles is still original....

I have a question for checking the fluid level. I flushed the fluid yesterday and on the last fill, I put in 3.75 qt. But after the road test, I checked the fluid level and it was up to the middle of the dipstick! I made sure it was completely drained before I tightening up the drain plug as to make sure there was anything left in the pan. I was forced to reopen the drain plug and drained out what I think was about 1/2 qt of fluid. But when I checked the level again, it was still near the middle of the dipstick, way over the 2 holes on the bottom. The car is still shifting fine, should I drain out some more fluid or am I checking the fluid incorrectly. I am checking it after it's warmed up and on level ground with the engine running.
On a different note, I have 30000 miles on it and I changed the air and micron filters too, man they were very dirty. |

Near the middle of the dipstick sounds way too high. Fluid will foam if the level is too high, and that is not good at all.
Might try a qt this time, and keep a close eye on it. It is difficult to say what is happening, except some fluid was obviously NOT draining out. Did you fully warm it between changes and let it run a while? I haven't done this procedure myself, so I am sure others will chime in on this that have done it.
On the filters, the micron is supposed to be changed at 30K. Sounds more and more like that is one schedule to adhere to.
Is this the first time you changed the air filter? I doubt I would retain a stock filter past 12-15K myself. |

Dale,
I drove the car in between the changes and made sure it went into all 5 gears. On the last drain, I left it draining extra long to make sure everything was out. Do you recommend I do a complete drain and fill or try to drain out another 1/2 quart and recheck? I think I might have already answered my own questions since I will have to change my crush washer now that I have loosened the drain plug couple of times to drain out a few oz at a time.
This is the first time I changed the air filter at 30K. It was too bad but maybe I'll consider 15K next time or at least check it to see if it's needed. Thanks. |
