I am aware of that, and I was in 2019 when the transmission went out on my Suburban. If I'd had the luxury of "bulletproofing" the trans I would have taken it.

But I didnt: When my transmission shit the bed, I was 300 miles from home (Vernal, UT) with my wife and a travel trailer that both needed to get home. So I bit the bullet and got the "factory certified" warranteed transmission and as soon as I got home I started shopping for a replacement truck.
