See the links in post #9. A transmission flush is a frequent trigger for transmission failure in a transmission that is otherwise performing well. That is why several of us who have worked in shops and have done overhauls on transmissions won't do transmission flushes on our own vehicles, unless the fluid is burnt. That doesn't mean that we don't believe in preventative maintenance, just that changing the transmission fluid often introduces new problems. You can check the links on this board as well for this phenomenon. The posts usually start with "I can't believe my bad luck, I just changed my transmission fluid and now my transmission has failed even though...." The transmission shops know all about this, it isn't in any way a secret.
