To those that say change when the fluid starts to look dark and smells a little burnt. Isn't that like saying wait until the tranny just starts to fail? Once the clutches start to wear, changing the fluid is not going to add material to the clutches.
When it turns slightly dark your transmssion isn't going to go out. As far as smelling burnt, that isn't the case either. Now if it's REALLY DARK and smells REALLY BURNT that's another story.
It's not going to look "factory fresh" after 30,000 miles. But that's not saying it needs to be replaced either.
