To flush or to drain?That is the question..Some or saying have the a/t system pumped out , mixing old and new fluid together fluid half changed, others drain with new filter.I'm leaning towards drain and new filter only presently. The a/t is working normally,the fluid condition looks clean.Last job pending.
