The Japanese version that I have does not have a dip stick so there is no way of really checking the ATF fluid condition for me

Does anyone have any idea why the Japs would put a dip stick on one model of a particular locatoin and not the other????

That's because you have the K41 CVT, which is completely different than the U340 automatic.

Oh i see. Do you know where I can get some info on drain / refill intervals for this transmission as the manual I have is in Japanese

Also if a DIY guide to do it is available on the net. Tried google but so far nothing.

AUTOMATIC TRANSAXLE

Fluid capacity (drain and refill), L (qt.,
Imp. qt.): 2.5 (2.6, 2.2)

Fluid type:
Toyota Genuine ATF Type WS

Change automatic transmission fluid only
as necessary.

Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF Type WS”
(ATF JWS3324 or NWS9638) to aid in
assuring maximum transaxle performance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
Type WS” may cause deterioration in
shift quality, locking up of your transmission
accompanied by vibration, and
ultimately damage the automatic transmission
of your vehicle.
Please contact your Toyota dealer for further
details.

I looked at the “Scheduled Maintenance Guide.” It never says when to change but it says when to check it. It says to check it pretty often.

I have 100K miles on my Yaris now. I bought it with 50K and don't know if the fluid was ever changed. I used the dipstick and saw the level was good. The color was purple, but a little dark. No metallic flakes or anything. I have no problems shifting (automatic).

Is it bad for the fluid to be a little dark?
Is there a good reason for me to change the fluid or even clean the filter and change the gasket as this website below instructs? (I know how much to use and to only use Toyota fluid.)

IMO...no....unless the vehicle has been in a flood or subjected to unusually harsh operating conditions like trailer towing, subzero operation, or very hot climate.

I check my level once a year and inspect the transmission for leaks while up on ramps for oil changes.

CT, are we to understand that if we want to do this at home we just need buy 3 quarts for a DIY drain and fill?

That's correct - About 3 quarts for just a drain and fill.

2007TRD posted a nice DIY on the Micro Image forum for doing either a drain and fill or a more detailed dropping of the AT pan to inspect the filter and magnets as well.

I see him talking about a Drain Plug Washer... have you seen this for sale online/ is it possible that my original one is fine and doesn't need replaced?

Thanks.

I changed mine at 81k miles , it was pretty dark compared to new fluid. Very simple, easier then oil change.
$8.99 qt from dealer and $3 for new gasket

can anyone take pic of the drain plug? i can't find it under the car...

bolt size is 10mm allen wrench or 10mm allen socket drain and fill 3 quarts is what i used but i dont think i used the full third quart check after 2 1/2 quarts and so on its a easy job

[caineroad]

According to me you can get help at Alta tech. They offer best auto fluid replacement services, complete repair at low cost.

I have one of these http://www.griotsgarage.com/product/...do?from=Search

I have used it on other cars. But on my quick mechanical analysis of the yaris. This car is almost made to be worked on! I mean im almost drooling to do an oil change on this thing and I havent even had it for 1000 miles yet.

I also took a look at the drain for the tranny. Piece of cake! invest in a alen socket for a 3/8 ratchet and do the thing yourself. And do it right. Replace the gasket and use toyota ATF I cheeped out and used universal atf in my old hyundai but it was a beater I didnt care.

Your already saving tons of money and doing it the right way (not the jiffy-idiot way)

But going back to the fluid extracor. It never hurts to change the fluid. So I might use it for intermediate changes between actual changes. Keep those transmissions clean boys! and they will last you many years of good hard service. Ive seen auto boxes go 300,000+ miles and ive seen them fail as early as 100,000 its all about the care, dont abuse them and change fluid and filter regularly.

Thanks

Also just wanted to include, that I would only use Toyota recommended fluid. I've seen plenty of time's when people use other transmission fluid, and it "burns" up right away, and the transmission doesn't shift as well. Spend the little more money and do it right. Don't forget to get a new gasket for the transmission plug. (Won' hurt to change it, every transmission service)

What is the gasket replacement you guys are talking about? Is there a gasket on the allen bolt you remove to drain? If anyone has a part number for it id appreciate it..
