Drain ATF, disconnect one of the lines from the radiator that comes from AT, run car in Neutral until flow stops and shut off car. Put ATF drain plug back in and reconnect hose, measure what comes out and put same amount back in through ATF dip stick, use Castrol Transmax Multivehicle fluid.

Is that the correct procedure? Do i leave the drain plug out while doing the part when you run the car in neutral?
