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.

Amsoil fixed 2nd grind on y RSX too.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.
And you've gone through what testing to prove this?
I'm most likely going to switch my MT-90 to this. I'm tired of the cold, slow turning and whining.M1 75-90 works fine for me..
Hmm, I might change to this then. Thanks.There is no tight turn whine with the Motorcraft. Shifts great.
How many quarts does the tranny hold?
