Okay, I have searched all of the posts on this forum and I am still not clear on what are and aren't acceptable fluids for the 900 Manual transmission fluid. I know that I have the "early" synthetic as mine is a 98. I wanted to swap it out for 10w-30 mineral oil since my fluid has gotten low i would have to pay a lot to fit the newer fluid as the older sythetic is not available as far as I know. I have seen people talk about using 10w30 10w40 mineral oil, synthetic oil, Red line MTL, Dexron III, etc. I wanted to know if anyone has used any of these and what their results were, also, does anyone know for sure what is acceptable and won't cause my transmission to fail?
Thanks
