yea, think maybe a fluid/filter change before additives. Don't know how keen I am on those kind of things being to oil/fuel/drivetrain, but not ruling it out either, Color ? don't know but like I said, the transmission mechanic that I took it to did not mention anything out of the ordinary, and it appeared red when I looked at the level before I took it in, but that was just off the dipstick, have not seen a larger quantity of it to gauge a difference. Still open to suggestions, but will mention a change of fluid/filter to the mech. tommorrow.
