How did the transmission act afterwards? Smoother? Quicker?

I've been needing to do this to mine for quite some time.

 

No difference felt. May be a little better shifting thats about it. I guess changing ATF fluid is a good preventative issue rather than putting in a new transmission.

 

Good write up. A few members have asked about this.

 

Yes very good write up you need to do this about every 10,000-15,000 miles depending on how hard you drive it. Very nice article.

 

nice pics! changing the ATF is very easy and is a really really good thing to do to our Honda automatics. changing the fluid resulted in noticably smoother shifting and just overall better performance on my 94 Integra with 150k miles. (when I started autox racing it I changed it more frequently.)

a few more tips:
-only use genuine Honda ATF. it has special additives that these transmissions need to last. $12-20 for the fluid is well worth it.
-get a funnel with a 18"? hose *before* you do this, that's the only way to get new fluid down to the dipstick hole!
-also use a new crush washer for the drain plug, torque it properly, and check for leaks afterwards.
-after you put the new fluid in, start the car and slowly shift through the gears. maybe drive around the block. then check the fluid level again.
-remember that the torque converter retains about a quart of fluid, and there will probably be some left in the radiator. so don't think you're getting a complete flush with a simple fluid change. I'd change it more frequently because of that, especially on older cars.. probably once a year I'd say.

 

eek

I'm about 50,000 miles over due.

 

this is easier than replacing engine oil, cause with engine oil you have to mess with a filter. This was damn easy with a torque bar. Just make sure you have a long neck funnel. Better than paying someone big bucks to keep in cheap oil.

 

good write up, also what tegtronic added is good too....i did those same procedures on my old accord after i had a problem w/it slipping out of gear......it was really easy, and after i did that, everything was fine and it ran really smooth. i guess i just had some old fluid! lol

 

do people use the redline or some of the other stuff?

 

Exactly where would the drain plug be? It might sound stupid but what exactly is the purpose of using a torque wrench over a socket?

 

Not to burst your bubble..but doing this is pointless.. you don't even get half of the fluid in the auto trannies out. Most of the fluid remains in the torque convertor, this is why they have automatic trans flush machines at shops. Hence also why you dont do a flush on a manual. Sorry to be the asshole here but someone had to say it.

 

A torque wrench is pretty much pointless when taking off a bolt. It will act just like any other wrench, except that you can only put a certain amount of pressure on it. However, when you are putting the bolt back on and you need to tighten it to certain torque specs, you can set the wrench to click when it reaches a certain tightness. So then you can torque bolts to match the factory specs, which is a big deal for certain bolts in key engine parts.

 

thanx but in regards to shadowhunters comments, how exactly is it done at the shop? They use a machine to flush it?

 

The process of the machine is pretty simple.
New fluid is poured into the machine. The machine is hooked up to the transmission cooling lines in the radiator or what have you basically making a loop between the tranny and the machine. Next the car is turned on and the machine goes. Basically it shoots in new fluid at the same rate that the old fluid is being extracted so the new fluid never makes contact with the old. When all the new fluid is in the car it beeps and turns off. Some places also add a detergent to the machine first so itll clean the trans out better.

Honestly I would HIGHLY reccomend this over a drain and fill to anyone with an automatic transmission. UNLESS.. You have a car with higher miles and a transmission that has has either problems before or is currently having problems and the fluid is much too dirty. Flushing the system then could result in your transmission not working anymore as it relies on the dirty fluid to keep the grip within the clutch discs. So then a drain and fill would be advised.

I work at a repair shop btw just in case anyone is wondering my source on this.

Great job, I actually did the tranny fluid change recently myself. Don't forget to put some anit-seize on that plug.. My Teg usuaully shifts smooth at first and then reverts back to the regular hard shifts after a few days, its normal.

You are correct Shadowhunter, most of the fluid is located in the torque converter, which is why it is EVEN MORE imporant to change your fluid regularly so that old fluid is recylcled with new fluid. This way you can avoid expensive automatic system flush at garages that will probably not do a throughout job, Especially since Auto tegs don't have tranny fluid filters.. I think this is a big misconception that you should never change auto tranny fluid, its ignorant to think that the fluid will last forever, over time fluid will lose its effectivness, and will not lubicate parts inside, causing more wear on your transmission.. Although you may have a point if your car is high milege and has never had a tranny fluid change.. My car from new has had regular tranny fluid changes to avoid this problem..my advice change your fluid often if you plan on keeping your tranny in top notch shape!

i would have to disagree with the idea of not changing old oil. many people have the idea that a transmission gets used to it's oil and if you change it it will damage the transmission. changing the oil cannot damage the transmission. if there is a problem in the transmission it will break and start slipping with old oil as well. if you neglet manitance, you pay for it. changing the oil may not fix the problem, if the clutches are worn/burned it doesn't matter how long the oil is in there it won't make a differance.

 

auto tranies only need 3 quarts of atf, not 4.

 

the teg torque convertor holds about 7 qrts.

 

Wow this thread came back from the dead.
In Regards to fordcourier72's comments:

When I mean dont change the old fluid I mean on a car that has high mileage with possible previous or current problems. Keeping up with your maintenence is a must and I am in no way telling anyone with an auto transmission to not change it on the reccomended service intervals if not sooner. Excluding the exceptions above.

Now When you said that the tranny will get worn out with the dirty oil as well you are correct.. to a point. Like I said there are two ways of changing the fluid, what I said was if the fluid is highly dirty and high mileage car then I suggest a drain and fill like in this thread. Now what you may not already know is.. The reason for not doing a transmission flush on a high mileage car with dirty fluid that you can possibly see clutch pack residue in is as follows.

The fluid that has those traces of clutch pack in it is what is keeping the transmission together if it is a high mileage vehicle,depending on the condition of the transmission if you flush the vehicle it might slip even more or not grip at all. Don't belive me? A guy at my old work did a flush on his old ass camaro car just slipped revved in gear and did not move. Also to cite another example, a ways back before I was in the automotive industry I brought my car to ammaco(sp?) to get a flush and filter. They called me back 20 minutes later saying they could not do it due to the fluid being so dirty and the shift points and intervals being off by so much that they did not want to risk the car just not even running.

If you are in any doubt to the condition of your tranny have an electronic diagnostic done, in some places it's free and then you can know if you should get a drain and fill or flush. The service manager at the shop you take it to can let you know what they think is best.

Hope that explained what I was trying to say.

u can also just do multiple drain and fills at short intervals that will essentially change all of the fluid since after drving the new will mix with the old in the TC equaling 1/3 new fluid and 2/3 old, then after another change it will in theory be 1/2 new and 1/2 old...and so on.....

 

where do u put the fluid in?

 

the answer is in one of the post on the first page of this thread. It also tells you what you have to use.

 

So the flush is pointless for a manual teg?

 

^^^is it???

 

where do u put the fluid in?

See the yellow handle for the auto tranny dipstick? Thats where you fill her up.Make sure to use Honda ATF fluid. 3 bottles should do it. Do not overfill.

Quote: tim on May/16/06 So the flush is pointless for a manual teg?


Tim, for the auto its mor crucial as the auto tranny uses to fluids to function. It is itself a hydrolic device. So no fluid, no workie.

In the manual tranny, all it does is lude the gears. Northing more, nothing less. But without it, the tranny also won't work, grinding.

Quote: atownakaatl on May/25/06 ^^^is it???

NO, not pointless as its 2 different things. Do the fluid change.
