This and it say since you changed your fluid the tranny has run great for 5k miles really means squat. 
You can actually damage an older transmission by changing the fluid, if it has never been changed and then suddenly you change it that could throw your tranny into a tailspin. If you have an old tranny with the original fluid in it better to let it run until it dies then to switch out the fluid.
