so am i getting this right, after i dump the old and put in the new, your suggesting 5 miles later dump my brand new $26.00 fluid and do it again ?
 
That is the procedure Honda recommends. Their mileage/time is different though. I've always thought that instead of dumping a certain % of essentially new fluid back to back to back (to back?), I spread out the D/F. Actually, on my '02 Accord it said 4 D/F every 60k miles for severe service so I divided 60k miles by 4 (4 D/F) to get 15k miles. I then cut that in half since they were having AT problems on those models. Otherwise, I would just do a D/F every 15k miles.

Once you drive it down the block, the fluid has sufficiently mixed with the old and you now have a mixture. The transmission holds approximately 9 quarts; after the first drain/fill, you have 6 quarts of old, 3.0 quarts of new. What you then drain out, whether you do it 5 miles later, 50 miles later, or 500 miles later, will be approximately 66% old fluid and 33% new fluid.

I'm on a schedule for drain/fill once every 15k miles on ours, only because it spreads the time out.

Yes, and you will notice that your brand new fluid is dark & dirty until you do it 3-4 times. Honda considers this a flush as they recommend you never use a flush machine on their transmissions.
with a 9qt trans and 3 qt drain you get:
1 drain fill = 33% new fluid
2 drain fills = 56%
3 drain fills = 70%
4 drain fills = 80%
5 drain fills = 87%

OK, so when we go to the Honda service department and get our $59.00 service done, and they TELL US that its due again in 30,000 miles there full of beans ??? this seems downright crooked to me.. why would they recomend 30,000 mi intervals ?

sheesh, i had no idea, so i need to go buy a case of DW-1 and start flushing ASAP as a service has not been done in 30,000 miles now.

i just did the math, im gonna spend around $130.00 on DW1 for 5xflush fills... this stinks !! My silverado gets a tranny service every 30,000 and the shop does it for around $90.00 pan drop and a new filter.. this is gonna be alot of draining and filling on this Honda !! im a little peeved. Im doing the work and it costs more than my pickup.. grrrrrrr I hope there is no damage from going 30,000 without any D/F

I just got off the phone with thompsons honda of terra haute indiana. I relayed all the information I have been given on this thread about dumping and filling. Thompson honda terre haute service manager says you guys are full of beans. He stated a transmission service on our 07 honda accord is required every 60,000 miles, with 3 quarts being drained from the system and and 3 fresh courts being added to it. Now I'm a loyal BITOGer, but somebodys wrong here. I can't check our manual as my wife has the car and were working opposite shifts this week.. I won't even see this car again untill Friday. Can anyone back up this 4-5 x flush fill method with documentation from Honda that its the correct procedure?
 
I'm glad you posted that. Now that I look at the service information for both of my cars (via Alldatadiy.com), neither specify doing the procedure more than once at a time. I'm pretty sure that that's how it USED to be, but perhaps that's just internet lore.

2008 Honda CR-V ATF Replacement
1.Warm up the engine to normal operating temperature (the radiator fan comes on), and turn the engine off.
2.Remove the drain plug (A), and drain the automatic transmission fluid (ATF)
3.Reinstall the drain plug with a new sealing washer (B).
4.Refill the transmission through the dipstick guide tube opening (A) with the recommended fluid. Always use Honda ATF-Z1 Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affect shift quality.
5.Insert the dipstick (A) into the guide tube (B) aligning the notch (C) with the guide tab (D).
6.Remove the dipstick (A).
7.Check that the fluid level is between the upper mark (B) and the lower mark (C) on the dipstick.
8.If the maintenance minder required replacement of the ATF, reset the maintenance minder, and this procedure is complete. If the maintenance minder did not require replacement of the ATF, go to step 9 and reset the ATF life with the HDS.
9.Connect the HDS to the DLC (A), and go to the BODY ELECTRICAL. If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.
10.Select ADJUSTMENT in the GAUGES MENU with the HDS.
11.Select RESET in the MAINTENANCE MINDER with the HDS.
12.Select MAINTENANCE SUB ITEM 3 RESET to reset the ATF life with the HDS.

2005 Acura MDX ATF Replacement
1.Bring the transmission up to normal operating temperature (the radiator fan comes on).
2.Park the vehicle on level ground, and turn the engine off.
3.Remove the ATF filler bolt and drain plug (A), and drain the automatic transmission fluid (ATF). NOTE: If cleaning the transmission cooler is necessary, refer to ATF cooler cleaning.
4.Reinstall the drain plug with a new sealing washer (B).
5.Refill the transmission with the recommended fluid into the filler hole (A) to the upper mark on the dipstick. Always use Honda ATF-Z1 automatic transmission fluid (ATF). Using a non-Honda ATF can affect shift quality.
6.Install the filler bolt (B) with a new sealing washer (C).
 
Otis,

Dealerships aren't the knowledge gods of maintenance since they have competing interests. Many times they will contradict the mfg & each other, sometimes to the good & sometimes to the bad. I've called the parts department & then follow up with the service department of the same dealership & gotten two different answers. Of course, BITOG isn't a maintenance god either. Both can be fallible. Also, there isn't exactly a perfect answer for this either since it is a variable. That's why oil analysis can help guide you. A decision has to be made of how involved you want to be in the vehicle maintenance.

Honda appears to have fixed most of their transmission problems pretty well after 2005. All mfg are going to extended oil changes. Some have backtracked after going too far.

You have to realize that folks on BITOG are typically aggressive, i.e. more frequent & better quality, on maintenance, than the norm. Another factor is how long you're going to keep the vehicle. 100-150k miles, then heck yeah, I don't see any issue with abiding by Honda's recommendations for everything.

I wish you luck in your quest for maintenance zen.

I see the logic in the fact that the tranny holds 9 quarts and your only dumping 3 and refilling three at a time, frankly i think 60,000 to dump / fill 3 qrts seems a little "lacking" but im no engineer or Honda service expert.. thats why i ask questions. I think im gonna do a dump fill this weekend and over the next 2 OCI's im going to do it again, thats 3 dump/fills over around 15,000 miles. I think this will make me feel all warm and fuzzy

well its my wifes car and frankly ive just not got all that involved with it other than oil changes,tires,filters. & of course im a BITOGer, im OCD about maintaining my stuff. But I think there comes a point when some might just be waisting good fluids with overmaintaining some things.. when i read some earlier post's red flags started flying and i knew id be calling the service department (and yes i 100% agree they are not the end all be all in maintence awnsers) I try to fall inbetween service center recomendations and BITOG recomendations

In all honesty, that is probably really smart. The biggest exception would be on vehicles that have weak spots, such as my '02 Accord transmission (although still going on original at 171k miles).
 
Update:

I pulled the plug and draqined 3.5 qrt's out of the Honda today.. of course i only had 3 quarts to put back in it of DW1.. but im getting a little ahead of myself.

First thing i did was look and realize how far down and how tiny the dipstick hole was, so i located the fill hole and using 3 frigging extensions pulled the bolt for the fill hole.

Next i found my drain plug and let her rip, when the drain bolt was out i emediately noticed what appeared to be grease coving the unthreaded tip of the bolt.. not knowing the purpose of this grease i didnt whipe it off (looked just like axle grease) not sludge.. (is this tranny sludge or is this grease ?)

when 3.5 quarts came out i replaced with the 3 quarts i had on hand and checked the fluid level, to my suprise the level was perfect with the top marker (this was without starting the engine)

I stopped on my way to work today and picked up 7 more quarts of DW1. I will top off tomorrow the .5 quart i didnt have on hand. my next two OCI's will be oil and tranny, so over the next 10,000-12,000 miles the car will dump and recieve tranny fluid three times.

*Notes* had to use two funels to reach the fill hole, did not have any splash guard to remove to reach drain bolt. I was very suprised that the fluid was that dirty considering it still looked pretty pink/red on the dipstick, it looked very dark brown in the drain pan.
 
More than likely, you have a "magnetic" drain plug. It will attract metals and other gunk. Next drain and fill you should wipe your drain plug clean before re-installing.
 
this sounds right, just was not sure.. never had the tranny plug out before. will clean in a few months when i do it again along with the oil..

side note* the tranny plug is magnetic, but the oil plug is not ? this is just odd to me. I purchased a new oil pan drain plug today for the accord as the factory one is starting to get a little chewed up, it doesnt appear to be magnetic but i could be wrong.
 
UPDATE: again...

So i open the manual today after one 3 quart dump and fill, and under tranny service it DOES describe Hondas version of a "flush" as emptying and refilling 3 times in short order with the fourth fill being the last.. so you dump 3 times and fill and your done with the fourth fill.. this means 12-14 quarts of DW-1.. So the Honda of Terre Haute service department that claimed BITOG'ers were "full of beans" IS the one who is full of beans !! I dumped and refilled again this AM, this makes twice now, i will use the last the quarts i purchased (9 total) tomorrow mornning.. I will have to go out and buy 3 more quarts for the last FILL for this flush to be complete..

I can see this two ways, the Honda dealer described to me what there regular "service" was.

I found in the owners manual what a "flush" is... the manual also states that no machines are to be used on the honda transmissions for flushing filling..

So BITOG'ers are correct..
