2008 auto transmission drain plug.

[sdotmurray]

Does anyone know what the metric thread callout numbers are on the automatic transmission drain plug for the 08 Yaris? I was thinking of changing it with a magnetic drain plug but I can't find this info online anywhere.

Thanks!

I wouldn’t worry about that. Just drop the pan, change the filter,. You should measure the oil that drains out, and replace it with exactly the same volume of the new fluid.

in reality a mag plug isnt all that beneficial in an auto....the filter gobbles up just about everything and anything metallic wont go thru the filter anyway

Buy a couple of those strong magnets from Harbor Freight and stick them on the outside of the pan.

Good idea except I think the oil pan is too round. I don’t think there’s any place flat. I have use those magnets and they are really amazing!

Actually I would have to believe the drain plug is magnetic that’s already in there.

The ATF pan on my 2010 already has two magnets in it. I imagine it is the same for the 08. Also the filter is more like a screen. I replaced my filter at the time, but i won't waste my money on that again.

No need for additional magnets. There are already 2 in the pan.

If you have the money and get a charge out of that kind of thing Why not change the trans oil and filter?

Is it really necessary? Probably not. Have I ever done it? No!

Now manual transmission oil I change that every 30,000 miles. Usually just like two or 3 quarts of that stuff. Automatic transmission oil there’s usually something like 8 quarts.

You pretty much answered your own question Bronsin. I don't get a charge out of doing repairs on my car. Plus a new OEM filter on Amazon is $64. I'll just keep doing a double drain and refills every 35,000 Miles. I'm at 215,000 and the thing runs great.

For what it's worth, I did not change the ATF the first time until around 140,000 miles when I noticed some rough shifting during acceleration on the freeway. Changing the fluid and filter took care of that.....Amazing.

BTW, the drain plug is not magnetic
