MS6 Fluid Notes & DIY Pictures

2006 Mazdaspeed 6 GT
OK, ordered the Redline MT90 through Amazon. Should get it by 11 MAY. I'm going to stockpile fluids (this, rear diff, and coolant) and change them all at the same time.

I know it says use 1.3 for the PTO and 1.1 for the Rear Diff my question is will this amount make it to the bottom of the fill hole? Like can I fill till it starts comming out or no? Thanks for the help!

I remember it being pretty much spot on, and the numbers are factory reference for a fresh fill. A few report using less, most likely if they don't drain the old out completely

the original fill for this car si motorcraft semi-syn, so thats probably what they used. no harm done. thats what i use since UOAs show good results and its CHEAP.

I did my oil, tranny, and rear diff this weekend. Here are a few impressions:

1. This was the first time doing my own oil. I've done all sorts of other things to my cars in the past, but I've never changed my own oil. I will be doing it myself from now on (at least in the summer months). Not only was it half the price, but I know what went in it.

2. ...I also know what came out of it. I will not be going long intervals any more between changes. That ish was nasty.

3. As for the tranny/PTO/rear diff, 23mm and 24mm box wrenches will work great all the way around, except for the PTO fill bolt. There is a frame cross-member that is right in the way. You'll want a 24mm socket for that one, perhaps with an extension. Whatever you do, though, make sure you can get at the fill bolt before you unscrew the drain bolt. :)

4. Personally, I didn't notice anything different in the way the car shifts. I can tell you, however, that I will sleep a little bit better at night knowing that all the fluids are brandy-new.

What intervals are recommended to change out the transmission, transfer case, and rear diff gear oil? My friend said that the transfer case and rear diff oil only need to be changed (on most cars) if there is a problem or every 100,000 miles or so.

Also, is there any sort of magnet in the transmission for picking up stray metal filings from the rare missed shifts? I feel I should probably change the transmission oil, at least, especially if the synchros really are brass, would rather not have metal filings circulating in there...

manual says for the rear diff and transfer case:

If the vehicle is operated under any of the following conditions, change the rear differential oil every 45,000km {28,100 miles}
a) Driving in dusty, sandy or wet condition
b) Extended periods of idling or low speed operation
c) Repeated short trips of less than 16 km {10 miles}

If this component has been submerged in water, the oil should be changed.

I take that to mean about every 30k.

Really, all three are fine.
I say you should use Amsoil. You'll just as fast find many who swear by either Redline or the purple stuff. Healthy argument gets made for some motorcraft fluid also (should be included in the first post by now...)

Any of them are very likely better than what you've got in there now if your thinking about changing em.

if you found this, you can find so much more, your questions were answered years ago, documented and preserved


Updated the engine oil section with notes on the use of thicker viscosity oils, quantity increase due to balance shaft delete mod and additional oil filters & their part numbers.
