DIY: ATF Change
first of all, i like to thank JmD_1901 for comming by and helping me on all the work and stuff, you the man!
this is a diy to change the fluid, not overhaul, over haul require flushing the whole system. this change only changes most of the atf, it does nothing to the atf that was inside your torque converter
ATF should be changed every 48000 miles or 48 months, under regular conditions. and it should be changed every 24000 miles, or 24 months in severe conditions (a lot of stop/go traffic, pizza delivery, hot weather conditions etc...)
Materials:
at least 2 clean shop rags. heck, make it 4
3/8 inch drive socket wrench, no sockets needed
3.1 quarts of ATF
something to catch old ATF
jack stands
relieable jack
shop light
1. turn on the car
2. warm it up till the radiator fan comes on
3. shut it off
4. keep the vehicle on a flat surface
5. go under the tranny and locate the bolt (might have to jack it up to see and such..)
remove the tranny drain bolt, it's the only bolt with a gasket and square shape drive, it's hard to see, it's right next to the sub frame, and a 3/8th socket wrench fits right into the square drive

6. remove the bolt, it requires a little bit of muscle
7. catch the atf (it maybe hot) fluid, make sure you have a clean towel around to clean up any mess. and make sure you have something to catch the fluid with

8. while the fluid is draining, look at the bolt you just removed, it has a magnet at the end, clean all that nasty shavings off of it
9. after all fluid has been emptied, put the bolt back in, and clean around the area
10. torque the bolt down to 36lbs
11. refill the transmission with new atf, with 3 quarts at first, and check the level, then add more as necessary
you are done!
i'll be back in a bit with a p/s fluid change and a coolant change,

Umm.. i dunno how Honda's AT is built, but i did change the AT fluid in a Caravan/Voyager befroe and i change the tranny filter too, but i dunno if our cars have a AT filter... havne't had a chance to take a look at the tranny on a lift yet (AT filter collects more of those shaving you find on the drain bolt

our cars do not have a atf filter, our "filter" is that magnet at the end of the drainbolt tip
the car runs smoother, and shifts more precise
before i changed it, when the car shift, it tends to disengage, and drop 2-3000rpm before it re-engage into the new gear, but now, it's sharp shifting. i hate myself for not doing it sooner
if you look at the pic of the liquid draining, that's actually dark brown, not red
i coldn't do the coolant because our car requires honda coolant, or else is corrose through the lines and such

I changed mine at 17K recently and noticed smoother shifting. It was already dark when I looked at it. And there is a fuel filter, but the tranny has to come apart to get to it.

But the manual doesn't say how much quarts the civic holds of ATF....I don't know why the Service guy at Honda said mecanics use 10 qts to change customer's atf....oh..maybe because they change , rechange, and change and drive and they need 10 qts..eh?
Yeah, when I had my ATF changed (I tried to do it myself but gave up. Next time I'm doing it myself) the acceleration improvement was HGUE. I remember pulling out of the dealership and the car just took off - at least as much as our cars are capable of doing. But it was a lot quicker than when I brought it in ...

I did the ATF flush myself...and acceleration was a lil bit better...but I think I added too much ATF...i had 3 quarts and 1/6...is that still ok...? and I didn't use a torque wrench.but I just tightened it as far as I could tighten that bolt..is that ok too?

i don't think a little extra would hurt it
if you are not sure you torqued it down correctly, check for leaks periodically for the next week, i think it should be fine, long as you didn't over tighten it

I've tried to do this DIY, however, I cannot fit the wrench into the bolt. It is obstructed by the sub frame of the car. Can anyone tell me weather there is any tricky thing or not? I haven't jack the car up, will this be the reason? Thanks!

i would definitly reccomend this DIY.
i just hit 30,000 miles and did mine today.
i couldnt buy honda atf becuase the dealership is closed. but i got penzoil dexron III atf and it seems to be working fine.
before i did the diy my gears would have problems catching. it would rev up about 2000 rpm before it locked into the next gear. no that annoying problem is gone! nice smooooth shifts.

I'm not sure about our Civics auto trannies, but some trannies are very sensative to the amount of ATF you put in. If you overfill you can cause more pressure inside the tranny which is not good for the clutch packs or torque converter. Also to much ATF can cause your tranny to overheat and foaming.
Also if you go by what our Owners manual says about changing the ATF it says to change drain, refill and drive a short distance and repeat this three times. Then do it one more time and your done. Read the manual for more specific instructions. You use this method to flush out as much of the old ATF out of the tranny and torque converter.
