Going to be changing the tranny and rear diff fluids on my 04 possibly this weekend. I ordered the oils online, then went to the local Mazda/Volvo dealer for the washers. They gave me 4 identical aluminum washers. They said they are used for Volvos but they use them for Mazdas as well and they are a little cheaper. Would these be OK to use? Like I said, all 4 of them are identical aluminum washers, silver in color, that look to be about the thickness of the rear diff washers in JDLs DIY pictures. I only ask because in the original DIY it says that there should be 2 copper washers and 2 silver. And the the tranny ones are a little thicker in size. Any help on this?

Well I don't believe a "complete" flush is every really done when changing your fluids due to all the crevaces that the oils can sit in. 100% of the fluids never really drain out due to this. I'm not sure for the engine, but I know for the MT (which may be the same for the AT, I'm sure someone will correct me if I'm wrong lol) but the amount needed is about 1.8 quarts. Regardless, you're probably going to need more than 1 quart so you're gonna have to buy 2 bottles. So if all else fails, just fill until it dribbles.

But as far as the tranny goes, you shouldn't need more than 2 quarts, probably not even as I said before.

Yes, it definitely is. They're called crush washers. When you torque the plugs, it crushes the washer and forms a tight seal. Using the same ones won't get you a proper seal and may cause leaks because the washer has already been crushed to most of its potential. They should only be a few bucks each at your Mazda dealer. And they should usually have them in stock because they perform this kind of maintenance on cars probably daily.

I did t he fluid change a few weeks ago and had the car up on 4 jack stands and leveled with a spirit leveler.
My wife used a palmolive body wash which comes in a pump containe and I used the pump. The pump fit nicely over the redline bottle and it takes me 2-3 minutes to fill.
This oil change was so easy with the right equipment.

Royal Purple
Just an FYI, I used Royal Purple 75W90 in the transmission and I was not very satisfied. It worked fine in hot weather but in cold weather (under 40F) the transmission felt like it had molasses in it.

Power!!
The best I've seen is a pump top that screws on to a 2-liter bottle with a tube coming out the end. Kinda like a hand soap dispenser. Worked really well. Just a lot of pumping...
