Is it Ok to do complete drain for AT transmission fluid ? According to my dealer Honda do not recommend full drain only about 3 bottles. But the question is if you change only 3 litters what about the rest?

Huh? When you drain your ATF fluid, not all of it comes out. A portion of old fluid stays in the tranny case.

TSX559

About 3 qt of oil comes out and the rest stays in the torque converter. Thats why you do a flush to get rid of the old oil. You would drain the atf. put new atf in. drive for a few miles. Then drain and fill again. You do this about 3 times.

Hi,

I'm getting ready to change my transmission fluid.
I'll try the method of removing the driver's wheel and partially removing the cover.
To loosen up the undercarriage cover how many clips do I need to remove plus is there one bolt that needs removing? Also to loosen the clips do you just pry it out with a screwdriver?
I searched but didn't find any pictures in other threads.

Thanks for the help!

I only removed 1 clip and 1 screw when I did mine. Be careful with the clips, they are very britle (mine broke) - that's why I did not remove the others. No need to remove the wheels. Have a breaker bar ready or some kind of a long tube to use as leverage when removing the bolt, they are so tight. Don't be surpised if there's a lot of small metal shavings on the bolt.

Good luck.

Because you drain out the drain bolt, screw it back in, and fill at the filler bolt until it flows back at you. The AT fluid travels through the torque converter, all sorts of passages and also through the bottom of the radiator, so you need to be able to check the level. The MT fluid just stays in the case.

What is the part number for the washer?
I found at least two
94109-12000 WASHER, DRAIN PLUG (12MM)
94109-14000 WASHER, DRAIN PLUG (14MM)

I bought my car (2004 5AT) with 84,000 miles on it. I have since passed 95k, so it was time to change the trans fluid. Since I haven't been able to find any pix, here are a few:







I found it helpful to leave the trans dipstick in (the one with the yellow handle) until after I had removed the drain plug. Once I pulled the stick, the fluid just gushed out. Also a definite must to replace the washer. My dealer gave it to me with the 3 quarts of fluid, so ask for the infamous "good will gesture" and hopefully get the hookup.

Thanks, Bergman. I'm about to change the Trans fluids in gf's 06 TSX. It has about 33k. A friend who works at Honda Corp recommends we do it every 20k. He says it's cheap insurance for him since he has all the tools and employee discounts. So I should have gotten it done about 6 months ago but never got to do it. Since I'm changing the front pads as well. I'll just try to do everything in one shot.

Back to the topic...do I just ratchet that squareish drain bolt? Or I need some sort of special socket? How did everything go when you did your flush? Anything tricky? Any tips about not making a mess? lol

Ratchet works great. I thinks the 3/8" will fit perfectly.

aaronng

Yes, I just use a 3/8" ratchet.

What is the torque spec of the drain bolt?

mars

5.0 kgf.m, 36 lbf.ft

And in case any one needs the capacity..

ATF Fluid capacity: 2.9L (3.1 US qt) at change
: 8.5L (6.9 US qt) at overhaul..

Thanks Bergman for the pics, I'm still contemplating on wheter or not to do it myself as it appears to be a PITA having to remove all the clips & engine splash guard.

mickey513

These are probably for the manual tranny. I don't have the part number off hand but the washer for the auto tranny drain plug is a 18MM.

lowend15

thanks for the info...is the crush washer the same size as the oil drain plug washer? Off the top of anyone's head?

atltsx

Went out to garage and checked. The tranny one is larger.

npolite

Yes it is a PITA since Honda reversed their engines. On our 6th Gen Accord I don't have to remove anything to drain it. Now on my sister's Accord I have to remove the entire splash pan to get to it and if it wasn't hard enough now Honda has changed from plastic screws which you could unscrew easily to these push button plastics clips which are prone to breaking.

atltsx

Yep. I had a 7th generation Accord before my TSX and it was a pain even with no splash pan.

TSXXY

hey guys, quick (and perhaps stupid) question: I was informed that some hondas, when changing the transmission fluid have a filter that needs to be changed as well. Is this true?

JLTSX07

I was always under the impression that the maintenance minder system in the 2006+ TSX's told you when fluids had to be changed? Am I totally wrong here?

mickey513

Update, I changed the fluid 3x with the Honda ATF fluid. Removing the drain plug and refilling was easy. The two parts I find easy, but annoying as hell was removing the splash guard underneath the car, putting it back on, and jacking the car up and down three times. I used only 1 new tranny drain plug washer.

If you were to ask me if I were to do it again ... probably not.

The fluid was $7.99 a bottle x 9 = $72 before tax. There are some "specialize" honda repair shops that will do the entire flush for about $120 with oem honda ATF fluid, not a bad deal.
