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.

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.

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

Thanks CT Scott.

In the 4th point - I cant actually make out the location of the CVT refill hole.

In the 5th point - why do you have to let the oil drain till it slows to a slow drip?


Thanks

I don't have photo of the location of the filler hole, but from this larger diagram you can see two round areas on the end opposite where the transmission meets the engine. The plug is located on the right side of the lower round area. It is a larger head bolt then the others around it and is has a thin gasket visible around its edges.

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
Sean Scott

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)

IIRC, doesn't the manual state the tranny pump needs to be wired up to flush out the AT fluid?


Tranny fluid change is part of scheduled maintenance in Canada, IIRC.

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..
