Yea, i ordered online and i spilled some so my tranny is running a lil on the low side until i get some more in so i would recommend getting 3 quarts for the tranny. This time when i add it im going to do it through the shifter. So much easier IMO

i just changed my tranny oil, 2 quarts just about filled it and i mean JUST! lol
my main reason for this is that im gettin a metallic grinding noise coming from the tranny at 8.5k rpm +. it sounds horrible, and if anything it is now a little louder now i have changed oil. gear changes are smoother but im still getting the grinding noise.
im worried and frustrated. anyone know what this could be?
thanks

Just make sure your car is level and top up through the filler plug hole until it starts to run or dribble out, that is the method used by Mazda and the correct one.

I am not a fan of filling up your trans casing through the shifter hole, too much oil and you could get seal leaks from the rear extension housing seal or the input shaft seal in the front., and you don't want too little oil either.

Not much room to fill the fluid through the top hole on the side of the transmission that is why I improvised that way.
The service departments my car has gone to seem to be technically challenged when it comes to putting the interior back together. I have yet to have it put back together the same way it went in. That may be why they do not fill it this way. Or they could have a pump that allows easier filling.

There should be a dealer located near you. Sometimes retail stores sell Amsoil but are not technically supposed to. I have been a dealer before but it is somewhat of a demanding job for doing it part time.

Not sure what the stock gear lube is but I know that it is not synthetic for the early models, have not heard on the newer 8s.

Changes for '09???
I read through the '09 service highlights and the forum to try and find any differences for doing this on an '09. Looks like we use the same GL-4 SAE75W-90 Tranny oil (will use Redline MT-90)
The Rear Diff lists 3 different ones, all API GL-5: Either SAE 90, SAE 80W-90, OR SAE 75W-90 (with note that this is not available from Mazda).
Did the '04-'08 list the same for the rear diff and everyone chose SAE 75W-90 as the one to use (planning on using RedLine 75W90) or did '04-'08 only list one?
Probably do mine in a month or so around 1500-2000 miles. Anyone do this yet on an '09? Same procedure, socket sizes, torque specs? I did see the tranny oil went up to 2.06 quarts, but rear diff stayed at 1.4. Any other changes? Couldn't find the washers at Rosenthall, they state for '04-'08 only. Will check my dealer but wanted any first hand knowledge of the members here first.
Thanks.

^ my '05 manual does list the same three types of differential oil (I use Redline 75w-90)
API Service GL-5 (SAE 90)
API Service GL-5 (SAE 80W-90)
API Service GL-5 (SAE 75W-90)*
* Not available from Mazda
You won't need new washers at your low mileage (I reused at 20k even tho' I had new).
