What Kedis82ZE8 meant was he wont bother to drop the pan and change ATF filter cartridge until 80K miles. Hell only do drain-and-fill before that with drain plug.But, you won't need to mess around with the new gasket and dropping the pan if you're just going to drain the fluid. Isn't there a drain built into the pan for this?I'm willing to try this out when I change mine but don't plan to do the filter until 80k miles. Just gonna drain and fill for now. I'll keep an eye on it if it does break down like bmninada experienced.
I'm tired of dealing with RTV... I've never had to use on autos but on power-sports repairs.
Changed mine today. Oil and filter.
So I checked it first and that was the result:
Considering it was brown colour, I decided to drain it,
3.2 L roughly
Should have been blue eh? It's good it's lifetime....... After I've seen the oil pouring out of the drain plug I decided to go for the filter.
Oil pan wasn't that bad as that japanese guy's at 13000km!
All the shavings were on the magnet.
Filter:
Cleaned the pan:
Put new filter, silicone, put back the pan and filled it up with 4L of new oil.
Haven't driven the car yet as the silicon is on cure.
Will update you on Monday.
Thanks for the post and pics! Good info. Any particular reason you decided to go with the silicon instead of buying the gasket?
Wow.....thanks for all the great pictures and explanations! It was really informative and interesting reading your post.Changed mine today. Oil and filter.

That. Working as a mechanic, Ive seen so many cars with gaskets leaking. Bad quality silicone or very old. One leaks too, but not as fast as a normal cork or rubber gasket.Silicon is the industry standard. Gaskets suck. They like to leak. Silicon/RTV, not so much.
Just try to guess if instead of having the rubbish put in one place, it would be floating all around your transmission and going in where they arent meant to.wonder what kind of damage that would do if the magnet didn't collect them? Thanks for taking the time to post all the information [emoji106][emoji108][emoji122]

I have several questions if you don't mind. Did you check ATF or coolant temperature before ATF level was measured? Did you measure ATF level with engine running and after you went through all gears? Finally, did you take intake airbox out while you're doing it?
Well said! And I believe Unobtanium's bad experience on his ATF flush is because he's been waiting too long to do the ATF "flush". Many people have said if you waited too long to change the ATF, especially doing the flush, it'd dislodge all the existing tiny debris which may actually cause transmission problems. And it'd be better off not to change the ATF if it haven't been changed for a long time.

The reason why those traditional cork or rubber ATF pan gasket is easy to leak is because they tend to be hardened pretty fast due to the heat.Mazda did design the thing to be sealed with RTV or whatever it is versus a gasket. I wonder why a gasket would leak though considering the transmission isn't under heavy pressure (right?). I guess its because the ATF fluid is super thin and easily seeps through crevices.
So here's a question.
I did my first drain/fill sessions around 71k, which admittedly I should have done sooner, but oh well. I was thinking maybe 30-40k around 100-110k miles, but wasn't sure. What do you think a good next mileage interval would be? Would it also make sense to just go ahead and drop the pan and change the filter too by that point and mess with this RTV or whatever?
My fluid analysis on drained atf says otherwise.Interesting. Last time in (something very minor) the service manager said to not change the tranny fluid that it was life time. Doing so was not a good thing.
