Tranny fluid

:
2007 MazdaSpeed3
I know the popular one is Redline MT-90, but is there any other brand that I can use? I can't seem to find any Redline MT-90 ANYWHERE where I live. I've seen that people had to order it from online, but I kinda wanna change the oil out sooner than later. Thanks.
 
The best fluid is Motorcraft Full Synthetic Manual Transmission Fluid. The part number is XT-M5-QS. Most Ford and L-M dealers have it in stock. Not cheap, but worth every penny.
 
The Cold morning 2nd gear grind 08cosmic3 test. Stock=grind, MT-90=grind, Motorcraft=no grind. Use what ever you want. I have read that the Amsoil is also very good but I solved my issue with the MOTO. Search and you will find much praise in many different forums about the MOTO. But then again use what you want.

Amsoil fixed 2nd grind on y RSX too.
 
And you've gone through what testing to prove this?

Personal experience as well as the fact that I have yet to find anyone who regrets using it in their MS3. And, as 08cosmic3 will verify, if a product makes me say something positive about my MS3 it simply has to be outstanding...(lol2)
 
I have not yet changed over my tranny fluid..im only @ 14000 miles...but when I do I will prabaly go to the motorcraft stuff...I myself have heard nothing but very positive reviews from it..Ive heard great stuff on redline as well..but it seems like all the forums really give that motorcraft high praise.
 
Yeah, i'm at 39k and will need a tranny fluid change soon. Was just wondering if it produces the whining noise like the guy asked but it looks like it doesn't.
 
2.85 according to the manual. Also, if it's a little whine and double clutching when cold deciding that it's a better product, that's really funny. If something is that runny when it's cold, I sure don't want to use it when it's hot out.
