    What is the best oil to use in a 2002 V40 auto Transmission. I trust
    Mobil 1 motor oil, and believe synthetics are best. Would Mobil
    Synthetic transmission fluid be compatible, the Mobil site made it
    unclear to me.

    What type of fluid does the car specify? As I recall, there's just Type
    F and Dextron, the latter being more common. Synthetic versions of both
    are available, they may offer slight advantages if the car is driven
    hard or in very hot climates but for most drivers there will be little
    difference. One brand is pretty similar to the next, they all have to
    meet the same certifications. If the transmission is not performing
    correctly when filled with the type of fluid specified in the owners
    manual then something is wrong with it.

    It performs fine, it gets cold here with hard city driving and I have
    noticed performance improvements on other cars even when changing out
    trans fluid with 10,000 on it. Manual specifies JWS 3309 p/n 1161540
    which means nothing on a refrence search

    That stuff was gimmicky, I read somewhere that the teflon in it was not
    only useless, but could build up and clog filters and other small
    particles. I think the advent of full synthetics pretty much killed it off.

    slick, wasnt that teflon, Idont think it did anything, I do notice a
    difference with mobil synthetics, I see 0-30 mobil 1 can be used and
    that is something I will use next, it can be used in place of 5-30 and
