I just performed maintenance item # 2 on Tuesday on my A.T.

When removing the drain plug (use the largest 3/8 ratchet you have) you are only going to get about 4 qts to drain out. This procedure is a "drain and refill service" and not a flush. I prefer doing this on a regular basis (every 10K) than doing an elaborate flush. Feel its safer not to stir up any contaminants. I recommend using Mobil 1 synthetic ATF.

Your owners manual should tell you the cooling system capacity. Use a 50/50 mixture to refill. Check level after system cools down because trapped air may of bled off.
