I've got a 2002 Subaru Forester with 97,000 miles on it. The dealer said I needed a transmission flush. I took it to my trusted mechanic. He said the liquid was looking brown & sent me to a transmission place he trusts. The transmission place twice asked me if I was having problems with my car. No I am not - it's running fine. Then they asked how many miles on it.
This exchange just made me uneasy - do I really need a flush? A friend of mine says that flushes are bad for the engine. What's the real answer here? Are they bad? Do I need one?
