Doesn't prove anything but the one in my truck is 50+ years old and hauled around a 2000 Lb Camper for it's first 28 years and then became my work truck hauling gravel, sand, mulch, wood etc and it's never had a thing done to it. Couple of the syncros are starting to go. I can imagine how those lease trucks were driven to break a NP435, one of the toughest transmissions ever made for light duty.
