Best way to flush tranny
I have a 2001 accord 4cy f23a4, not sure what the tranny is anyone know?
What is the best way to change the fluid, its been neglected for like 70,000+ miles seems to be runnig fine though a little rough in the cold and kicking into reverse sometimes. I dont have access to a honda dealership near by so im thinking of going with mobile one synthetic ATF. How exactly is the best way i was planing on draining filling and driving a few hundred miles like 2 or 3 times then changing the filter and filling up. How exactly do you flush to mobile one though i mean since the tranny doesnt drain all the way is it safe to just start using the mobile 1 stuff?

You should use Honda ATF-Z1. If it isn't close by, then make the drive to go get it or have it shipped.
That's pretty much how you do it, except there is no "changing the filter" unless you disassemble the transmission.
You will need 3 quarts of ATF-Z1 for each drain and fill.

Re: Best way to flush tranny
Flushing a high milage tranny that has been neglected can cause more problems than good so be prepared for symptoms to pop up that were not there before. Ask the dealer for an additive for the tranny too and put that in on the last flush, some type of OEM enhancer to recondition the seals or a high milage additive that Honda recommends.
I would do even more flushes with a good but cheap fluid, these initial flushes will do all the cleaning, then, use OEM fluid as has been described above.

Re: Best way to flush tranny
hmm well i dont have the original transmission anymore it was replaced with a new that has the extra oil jet or whatever, im not really having any problems either just feels a little rougher its not slipping gears or anything. The book that came with the car says every 60k miles the first time then every 30k.

Re: Best way to flush tranny
As far as the flush goes... and keeping in mind that I have absolutely no experience with Honda automatic transmissions but this is prescribed for older Volvos and I've also done it on my Camry...
Parts:
Empty milk jugs, marked with a black market to indicate quarts
ATF (Honda, look at www.handa-accessories.com if you need a source)
Transmission funnel
About 6 feet of clear plastic hose, 3/8" ID if I remember right
Procedure:
a. Disconnect the line from the radiator to the transmission, slip the plastic hose onto the nipple. Put the other end in a milk jug on the driver's side of the car.
b. Take out the transmission fluid dipstick and put the funnel in. Have several quarts of ATF nearby with the caps off. Start the car. As the milk jug fills up, be adding fresh fluid through the funnel in the dipstick tube. Change the milk jug when it is full of course.
c. While the car is running and with the foot on the brake, shift through each gear for about five seconds per gear.
d. When clean looking fluid starts coming out, stop the car. Reconnect the transmission to the radiator, let the car run a little bit and check the fluid level, add fluid if needed.
And for what it's worth, my Camry has 175,000 miles on it with a strong automatic transmission and my Volvo had 160,000 miles with a strong automatic transmission when I sold it.

Re: Best way to flush tranny
i just got back from the dealer spent a hundred bucks for nine quarts of atf! Anyways he told me to do 20 mile between each drain? Is that correct becuase it seems most people say a few hundred.

Re: Best way to flush tranny
you really shouldnt mess with flushing the trans fluid unless it was done on a routine basis. and yes that pic on autozones site is a trans filter but on hondas the trans has to be pulled apart to be replaced... changing or flushing the fluid after sludge build up can make the sludge clog up the trans fluid passages and cause more problems...if you want the filter changed the trans has to be rebuilt for the most part so theres your flush done

Re: Best way to flush tranny
I think flushing it on a machine is what kills it not slowly changing out all the fluid, could be wrong.

Re: Best way to flush tranny
either way i think can cause the same things to happen... the new fluid cleans the sludge up which in turn loosens it and can cause it to clog up the trans, but its a risk. if you get the filter changed that will clean all the trans out cuz the trans will be taken apart so from then on you would need to have it flushed on a routine basis

Re: Best way to flush tranny
OK, I have a question.
I have a 1993 Accord EX with 180K miles. I bought it 4 months ago with 173K miles on it. So far it has been a great car. No complaints.
I have no idea about the maintenance on the automatic transmission. I haven't really had any problems with it.... Is changing the fluid something I should do?
I don't want to ask for information that has already been given, so I'll just keep reading but I don't want to create a problem. At the same time, I want to take care of this car as I need it to last me at least a year or so.
One more thing. I don't have a LOT of experience working on cars. I have replaced brake pads / shoes and changed oil / oil filters. Just minor things. Is changing transmission fluid / flushing something I can easily do myself?
Thanks for your input.

Re: Best way to flush tranny
rule of thumb for any automatic trans...if you havent kept up the service changes on it dont change the fluid after alot of miles are already on it...pretty much if its not messin up and the fluid doesnt smell burnt, dont change it
