    I have a car with a 727 TorqueFlite. Is ATF+4 the correct stuff now
    or is Dexron the best?

    I would suggest checking Allpar.com in the transmission section. I
    believe that ATF+4 is more expensive than Dexron II, so Dexron may be
    a better choice for your older mopar.

    Since ATF+4 is thin and synthetic, wouldn't it ruin and old TorqueFlite?
    Cause slippage, etc? Would not use it in a '64 Dodge Dart!

    The way I understand it, ATF+4 is a semi synthetic ATF that is
    backwards compatible with any and all Chrysler transmissions.

    Viscosity wise, I think all ATFs are about the same. The key advantage
    with ATF+4 is the high heat handling capabilities. You could visit the
    Valvoline web site and send an email asking for advice on which ATF
    they recommend. Keep in mind that today's Dexron II and Dexron III are
    also semi synthetic fluids.

    The old A727 and A904s could probably live well with Dexron, or ATF+4.

    Good Luck, Bill
