I went to change the transmission filter/fluid this weekend on my '99 Mazda Millenia S (2.3L) with 77K miles on it. Anyway, I went to Autozone and the guy told me that they do not carry the filter nor the gasket for the transmission pan. I then went to Pepboys and the guy sold me a trans filter kit that included the gasket for the pan.

The problem was that it was not the right kit for the S model of my car (the 2.3L supercharged), but rather for the ho-hum 2.5L. The gasket for the trans pan was clearly not the right one. I didn't bother removing the pan as I didn't want to reattach without a new gasket.

I had already drained the transmission fluid at this point (there is a drain plug), so I went ahead and filled the car with new transmission fluid.

Ok...So did I just waste that transmission fluid? Can I put off replacing the filter for a while, or should I go ahead and replace the filter as soon as I can get a hold of a filter/gasket?

Like hondas and other Jap cars there is no filter, BUT a screen in your trans. So you might be ok with juts a drain and fill.

This is what Advance has listed for your car


Looks like advance might have what you want? That and I never get my trans filter kits frfom autozone. There kits use a plain cork gasket, I don;t like cork for trans pans.

I believe the Millenia S has a non-serviceable filter and the only way to service the transmission is to drain and refill it like you did.

It?s been over a year since I worked one so I might be mistaken.
 

Quix is correct once again, what you can do is remove the pan and look for a magnet, if none is found you may put one on the bottom of the pan where it will not touch or interfere with the valve body or internal linkages.

As for the pan gasket, clean both gasket surfaces throughly with Brake Kleen then apply a bead of high temp, oil resistant Permatex gasket maker, let it tack up and then carefully bolt the pan back into place.

Thanks. I will have to take a look at Advance for this part.

So you are saying that there is no filter...or that there is a filter that is not serviceable? The magnet you suggest...is this a way of creating a "filter" by pulling all the metalic particles in the liquid to it? How often should that magnet be replaced?

Thanks for the link on the gasket maker...pretty cool stuff. Does that stuff come off easily if I opened the pan again or is it a pain to remove once you have used it once?

Thanks everyone for the help.

There is a filter but it is non-serviceable, the magnet will capture any metal particles floating around your tranny.
You do not replace the magnet, you clean it every time you change the fluid ;)

The gasket maker acts just like normal silicone sealer, it sticks to everything, you must scrape it off and apply a new bead every time you remove the pan.
 

To blow up the tranny so the manufacturer can make more $$$$$$$$$$ :)

This is one of the reasons why Asian built trannies do not last nearly as long as American built trannies do.

In actuality, the Asians do not have the knowledge base and experience as the American engineers do, they do not realize that we drive like lunatics here and as a whole do not service our vehicles as required.

Actually, there hasn't been any drips yet. My dad's truck's been fine as well. My mom's '90 Cherokee has seen better days though (whoever invented the cooling system should've been fired)

...out of a cannon. (happy?)

And Dodge stands for "Don't Overestimate Dodge's Gas Economy."
