I've seen trucks run for 200,000+ miles and never touched the trans. I have also seen them run for 30,000 miles then change the fluid and start having problems. I have never been one to touch the trans. unless I have to. Just check your fluid, if it doesn't look or smell burned up then it is fine. You have to approach engine oil and trans. fluid completely different. You don't want to change it just to change it IMO
