    Just read a post on Car & Driver's forum about a guy with a 07' WRX
    who complained about the shifting like I do. He said and I read that
    GL 5 gear oil will corrode and shorten the life of syncros if they are
    brass or bronze. I had read it will cut it in half, and only used if
    there is Another reason to use the oil. I wasn't sure the material of
    the syncros, so was waiting to find out for sure, but he says they are
    brass, and the trans oil goes into the front differential, and why
    the GL5 is used, which is good for the diff, but not the trans, and he
    switched to Redline 75W-90NS. He also said the shifter had a rubbery
    feel and replaced the bushings with polyurethane ones, and says there
    is some vibration, but a feel of the trans working.

    I don't notice a rubbery feel, but more of a notchiness. Maybe
    feeling things working would make me feel more in tune with it, but
    that can wait. Protecting the trans, as long as the diff is also, and
    smoothing the shifting would be nice.

    engine/gear oil and never the twain shall meet. :>)

    That's what I figured, but didn't search. Maybe he meant Sube
    recomends the same gear oil. I saw Sube parts on line sells the
