I changed my mustang transmission fluid about a year ago with castrol atf mercon fluid. It was red when I put it in. Today I drained a little and it was gray. Is this normal after only one year?
I changed my tranny fluid a few days ago for the first time. About 4qts came out, so it was the old recommended fill level, so it's been in there a while, probably since it was new 60,000 miles ago. It came out cherry red.
