Mine has never been fully flushed, and I'm worried about flushing it from the stickies I read. The car only has 53k miles on it, auto transmission. If it's never been flushed before, I read that deposits clogging cracks and such are cleaned away..and eventually killing the transmission due to leaks/overheating etc.
So along with the original poster, I am concerned about doing this. Can anyone tell me for sure if I should change it or leave it? Of course otherwise I would have changed it a thousand miles ago, but I've waited.
