Last weekend, I was talking with a friend who recently had some transmission issues after several years of driving. It got me thinking about how often I should actually be changing my transmission fluid. My car's manual gives a range, but it seems so broad that I wonder if there’s a more precise interval people follow regularly. Has anyone noticed a big difference in performance or durability by sticking to a strict transmission fluid change schedule? I’m also curious if different driving conditions, like city versus highway, affect how often you should change it. What’s your personal experience with transmission fluid change intervals?
