I've always been the person that never changes tranny fluid on my vehicles. Probably won't on any of my cars going forward. However, this truck is the "work horse" and I'm pondering if I should, since its being used harder. I say harder because the max tow rating of this truck is 4700lbs and my camper is ~3500lbs.
Thoughts?
On my 2011 Siverado half-ton the manual states 50,000 for severe service and 100,000 for normal service. I tow a trailer much heavier than yours and mine looks ok at 40K thus far. However, I have the six speed transmisson. With your tow rating it looks like you may have the old 4 speed. The owners manual will tell you.
