I have a 2000 suburban. I have never changed the AT fluid. I have heard over the years that if you wait too long to change it you may as well not change it as when you do, the new fluid will cause problems with the seals. I have no idea whether there is any truth to it or not. Maybe some of you gurus can tell me whether or not there is any merit to this claim.
BTW, I am currently at 170K and having no issues with my transmission.
