Ok, I've owned my 2004 GT1 since it had 8k on the odometer. It currently has 173k miles on it. The transmission fluid has never been changed nor have I ever had to add anything to it. (Yes, I know please begin the verbal abuse). I have no signs of slipping or hesitating at all. However I've never beaten on the thing either. It's my DD which I put 80 miles on every day with it being 95% highway.
So as I was addressing the LIM gasket issue over the weekend, I started to ponder the changing of the tranny fluid. I don't know what I should do. Since it's not showing any signs of failure, should I just leave it be or go ahead and change it. I've heard story's of high mileage tranny's going south after recent fluid changes.
