    Like the title says I want to change out my all my fluids. It's an 03 manual v6. What fluids do I need? How much? What weight? What's the best brand of synthetic? Are the t-case, tranny, and diffs the only things that need to be changed if I wanted to hit everything?

    Redline MT-90 is a GL-4 synthetic oil frequently recommended around here for manual transmissions. I recently changed to this and got smoother shifting when its cold. My five speed used 2.7 qts.

    Since I don't have a 4W drive truck, I'll let someone else handle the other parts, but GL-5 90w is generally recommended for rear differentials. (or a multigrade oil, like 80-90w)

    It tells amounts in the owners manual but I just did this a month or two ago. I used Redline MT-90 in the transfer case & tranny. If I remember right you will need 4 quarts for that. In the diff's I used Valvoline full synthetic 75-90w. Well I used that in the rear anyway but auto zone only had enough for the rear so in the front I used Delo full synthetic 75-90. Don't remember these amounts at all but the rear was I think almost 3 & the front is only 2 something like that.
