Car Forum / Honda Cars / March 2007How do I change my transmission fluid?
Can anyone tell me how to drain the tranny fluid myself? Where is the drain plug? Do I need a crush washer? 2002 V6 Accord 35k Thanks. Dill a 1/2 inch hole at the bottom. . > Can anyone tell me how to drain the tranny fluid myself? Where is the > drain plug? Do I need a crush washer? > > 2002 V6 Accord 35k > > Thanks. ------------------------------ www.slhondaparts.com has your diagrams and part #s. Use a 3/8 socket HANDLE without socket, normal thread. Make sure to remove fill plug (dipstick) and tranny should be warmed up just before draining. Use ONLY Honda Z1 fluid, and do it three times (weekends) or run it through all the gears between drains. Magnet will be heavily coated and drain bolt will be VERY tight first time (nobody knows why). 'Curly' As Curly mentions, when you take the bolt off you need wipe off all of the metal goo that is attached to the bolt. Also replace the crush washer and use a pole if you need extra leverage (I end up always needing it). I just believe that it may be overkill to replace the fluid three times. I doubt most Hondas out on the road that have over 150k miles baby their cars as we do and they are still fine. I would change it once wait a week and do it again and that's it.

That is the factory specification. You only get some of the fluid out with each drain. You need to drive the car a hundred yards or so between drains to exchange the fluid that's stuck in the torque converter. If you regularly do a drain/fill two or three times a year, you can get away with doing only one drain/fill each time.

For a full exchange, that's the factory specification (as opposed to a "flush" which is not recommended under any circumstances). For a routine transmission fluid service, they specify a simple, single, drain and fill. >> > As Curly mentions, when you take the bolt off you need wipe off all of >> > the metal goo that is attached to the bolt.

I've recently been following a couple of highly interesting threads in rec.autos.tech. In that group, a working tech with lots of transmission experience described the flush procedure, plus his many observations of disassembled transmissions. 1) A "flush" is not what I was thinking it was. 2) Sludge does not build up inside the valve body or shift valves. Conclusion: The prohibition on "flushing" is "Internet wisdom". There is nothing wrong with a "flush" as routinely performed by garages.

Interesting read! JT > Conclusion: The prohibition on "flushing" is "Internet wisdom". > There is nothing wrong with a "flush" as routinely performed by garages. Except that Honda specifies only multiple drain/fill/drive cycle to replace the fluid as completely as possible (if that's your goal), and not any kind of a flush. It's not Internet wisdom; it's Honda engineers. I'll take the Honda engineer wisdom any day over "some tech who does a bunch of tranny work". >>Conclusion: The prohibition on "flushing" is "Internet wisdom". >>There is nothing wrong with a "flush" as routinely performed by garages.

It also ensures that Honda will sell three time as much oil as would be needed in a conventional system that has a drain plug on the converter where most of the fluid resides. Utter cheapness on Honda's part, (bean counter engineering), IMNSHO.. Also, as I stated in another post, an independent shop that specializes in Hondas near me has been "flushing" automatics for years without incident.

Again, Honda doesn't specify the multiple cycle drain/refill as a regular maintenance. They specify only a singly iteration as the regular maintenance. They specify the multiple cycle drain/refill only for those times when a fairly full replacement is desired, and that is not the case for regular maintenance. > Also, as I stated in > another post, an independent shop that specializes in Hondas near me has > been "flushing" automatics for years without incident.

I think that we'll hafta agree to disagree on this one. To me, anything less than a totally and easily accomplished fluid change is like taking a bath then wearing the same ol' soiled socks 'n underwear... <G> JT (Who hates strange rashes...) >>> Conclusion: The prohibition on "flushing" is "Internet wisdom". >>> There is nothing wrong with a "flush" as routinely performed by garages. [quoted text clipped - 14 lines] > another post, an independent shop that specializes in Hondas near me has > been "flushing" automatics for years without incident. it's such a crock when they say stuff like that. "without incident" means what exactly? no fireball explosion? no leakage? do they actually monitor individual transmissions? over what period? what i usually see is it gets "flushed" with non-honda atf, the shift quality goes to heck, and the transmission gets replaced because "when they start to shift like that, they're just about to go". i got my 89 civic like that. 106k genuine miles, shift quality all to blazes. chick selling it couldn't offload it fast enough as she'd clearly been terrorized about cost of replacing "the inevitable failure". here i am 57k later and that transmission is smooth as silk thanks to drain & refill with genuine honda atf. and don't get too panty-bunched about frequent transmission oil changes either. look at the change schedule in the owner manual and believe it. friends had a 360k accord that had *never* been changed. worked perfectly. >>>> Conclusion: The prohibition on "flushing" is "Internet wisdom". >>>> There is nothing wrong with a "flush" as routinely performed by [quoted text clipped - 19 lines] > means what exactly? no fireball explosion? no leakage? do they > actually monitor individual transmissions? over what period? Sorry Jim, but I'm with Michael on this one. This shop which is in its thrid generationn of family ownership with a loyal customer base is proof 'nuff for me. I never subscribe to much of the hype offered by manufacturers including Honda where most of the profit exists with "service" after the sale. > what i usually see is it gets "flushed" with non-honda atf, the shift > quality goes to heck, and the transmission gets replaced because "when [quoted text clipped - 4 lines] > 57k later and that transmission is smooth as silk thanks to drain & > refill with genuine honda atf.

It won't in Texas. Dino based fluids go kaput shortly after 50K.

If they weren't performing satisfactory work, they would be out of business. >> I never subscribe to much of the hype offered by manufacturers >> including Honda where most of the profit exists with "service" after [quoted text clipped - 4 lines] > "extra profit" built into their schedule. all the profit is with the > shops that have you spending money on excess oil changes. Uh, when I said "service," I implied the whole scheme of "service after the sale." That is where the real profit(s) lie. >>> what i usually see is it gets "flushed" with non-honda atf, the shift >>> quality goes to heck, and the transmission gets replaced because [quoted text clipped - 8 lines] > > do you /know/ they use honda fluid?

If it still looks bad (or worse, smells cooked), change again. If not, then go to a 15,000 mile schedule. The "change three times" deal is overkill for most people. Would recommend it though, if you do a hellacious amount of stop n go in hot temperatures. The crush washer is probably 18mm like on 7th generation Accords. As I recall, older models (my old '90 Integra) used the same 14mm as the engine oil drain. > Must use Honda's Z1 fluid. Change once now. Look at the fluid after > driving to mix.

Honda specifies that only for people who wish to exchange much of their fluid for some reason. They specify NO flush, but rather the drain/fill/drive/ threepeat cycle. When the service schedule says "change transmission oil," it means pull the plug, drain all you can, and fill back up. Period. Thanks all! |
