I just did a complete ATF flush and refill on my 2000 Ody as some people have suggested on this board. Previously, I did a drain and refill at 45K and the infamous “3X” drain and refill by a dealer around 95K. Now the car is over 130K and I started to feel little sluggish lately. The whole process took less than 3 hours including a Magnefine filter installation. Here are the pics. Many thanks to all those people who’ve posted HOWTOs on this project.

Parts needed: case of Honda Z1 ATF (12), Magnefine filter, 2 hose clamps


Tools: screw driver, hose cutter, 3/8” drive ratchet, ½” drive handle + long extension (>12”), 17mm socket, [not in pics:] oil drain pan, measuring bucket (enough to hold 3qts), 12” clear hose (3/4” in diameter), roll of paper/shop towels


Remove the plastic splash guard on the bottom of the engine compartment. Use a screw driver to unplug bumper and fender plugs.


Remove the ATF fill plug using a 17mm socket with long extension. Newer Odys or rebuilt trannies may no longer have this fill plug. Use the dip stick tube instead for refills.


Use a ¾ driver ratchet to remove the transmission drain plug.


Drain ATF. Slightly over 3 Qts should come out.


Clean the gunk around the magnetic part of the drain plug and screw it back in with 36 ft-lbs torque.


Refill ATF. Pour in about 3 ½ Qts.


Cut returning ATF rubber hose on the driver side. Don’t do this if you’re not installing a Magnefine filter. You can simply remove the hose from the ATF cooler.


Insert one end of the clear hose over the factory hose on the radiator side. The other end should point to the measuring bucket.

Changed fluid twice and installed a magnefine filter yesterday at 137,000 miles on my recently purchased 2,000 Ody Lx. Not too difficult of a job, probably the hardest part is taking off/re-installing the splash guards.

I don't know if its fortunate or unfortunate that it still has the orig tranny in it...seems to shift allright as of now. Bummer knowing the tranny is the weakest link in these vehicles.

Thanks a bunch. I am still confused about a couple of things.
  1. Which hose needs to be cut. Can you show a more wider picture as when I peek down there in my Accord's engine bay, there are two rubber hoses both leading towards the tranny (I take it one is taking the fluid to the tranny cooler and other, back to the tranny).
  2. After the cut, when you start the car, won't air be sucked up from the other end of that hose that was cut?

Bump and another question.

Can I just order the factory Tranny hose clamps and use them to put in the magnefine or would I be better off with the screw on type clamps shown in the Pix?
Details, details

Took a look at the a picture of the accord transmission and the layout looks just like the ODY..

The line to be cut should be the one closest to the drivers fender (short and straight piece)..

Air won't be sucked in, this is not a vacuum line. The ATF just flows through this line and then drains into the sump... (just think of what happens if you cut a garden hose...)

I originally used hose clamps but then switched to the honda spring style clamps...
Thanks. I had gathered that the line coming out from near the corner of the radiator needs to be cut from the ATF Cooler instructions but wanted to be sure before I cut it. I will go ahead and order all the parts (need more than just this) and then attempt the flush in the coming weeks.
MAGNAFINE FILTER SIZE

Want to order a magnafine filter but unsure of size. Is it 3/8?
The correct size is 3/8 inch for ATF and PS.

Second filter down in 3/8 inch size. Buy 3 or more to save on shipping. No quick connects needed - comes with clamps already.

I flushed my ATF today using these instructions and 20 quarts of Amsoil ATF. I drained and filled the pan, cleaned and reinstalled the drain plug. I have the oil jet installed, so, I filled using the dipstick hole and 3/8" ATF cooler line a purchased and a funnel. I used the return line and another 3/8" ATF cooler line and flushed the ATF 2 quarts at a time. I used all 20 quarts that I purchased and the ATF still wasn't as clean as the new ATF coming out of the bottle. I drove around for a bit, and checked the ATF level. Everything is perfect.

The car shifts better and goes into gear just fine. I am a big fan of Amsoil's products. I would highly recommend using their ATF. Just make sure you flush the whole system when switching ATF. Amsoil ATF has Honda Z-1 speced for it as well.

3/8" will work fine, I installed 2 of them previously.

For those of you in Indy the Magnefine distributor is in Noblesville and is meeting me to save me money on shipping!

Holy Toledo, 20 qts.? 2 Qts at a time? Did you drive between changes? This is pertinent because if you don't, the fluid to lock up the torque converter passages will not be flushed.

I did a 3 times drain and fill 3.4 qts. at a time and also a final one with driving up to highway speeds locking up the torque converter several times. Afterwards, with the final change, the drained fluid looked like the new stuff going in.

If your's looked dirty after 10 changes of 2 qts. each, you might not have been circulating all the old fluid out?
tag....
just flushed the trans and added the magnefine filter on my 01 ody with 56k miles on it.

I have the van on jack stand since I was also doing the oil change. I basically broke every small clips when removing them.
Also, I used a utility knife to cut the returning hose and some ATF came out from the hose and went on my face..... I tried to cut it close to ATF instead of radiator to get more room and flexibility when installing the magnefine filter.

1. first drained and added 3 1/4 quarts honda ATF
2. drain and refill 2 1/2 quarts X 3 times
3. installed the magnefine filter and check the level of ATF

it took me almost 3 hours to finish everything, including oil change, tire rotation and ATF flush. Not too bad for a sunday morning project.

just a follow up..
drove the van for almost 100 miles after the flush.

paid extra attention on the shift smoothness as well as on the whining sound with 4th gear at lower rpm. There's no doubt the shifting now is smoother, especially from 1st to 2nd. However, the whining sound is still there but seems become not that noticeable. But I don't have any solid proof, just my own "feeling".

I will surely flush the trans fluid again when I do 90k mile service.

Jason
pickupjackson: Given your relativley low mileage and the vehicle history...you shouldn't have any problems with Honda's 109K warrantee. Just keep your reciepts for the ATF-Z1.

If it goes, then I'd definitley add a cooler as well to it (aftermarket).

You should add your mileage to your signature (which I think is around 56K).
Oh yah...if EGADS hasn't already told you...flush your brake fluid.:D

Our whining in 4th gear with the torque converter locked between 65-75 or was loud enough to overcome ambiant hwy noise. And we had a whine between 1st and 2nd.

These 2 symptoms lasted a few thousand miles and then the tranny coded!

Does yours whine bet. 1st and 2nd?

:rolleyes:
the 4th gear whining last for past 30k miles...
I do not hear any whining between 1st and 2nd...

This is also the reason I want to do a "flush", just want see if change out most of the fluid will help the "shift" quality and the whining...
so far so good..

Jason
Is your current fluid nice and red from the previous changes? And between those d/f's, did you drive it on the hwy to lock the converter?

:confused:
well, the first drain, 3 1/2 qt, looks dark and kind of "smell"...
during the 2nd/3rd drain and refill, I see apparently difference since there are more and more new fluid in there. Also, I did not drive the car between drain/refill. I know there are some discussions between drive and not drive but since I have the car on the jack stand, I just decided to do the drain/refill without driving in between.

Anyway, the result is promising to me and I will surely do that again at 90k, if I keep the van till then..:D
