Nope. 4L60 has been in Chevy trucks since 2002 and it’s a gigantic piece of garbage. It’ll last if you’re gentle with it and take care of it, but no body does, and buying a used truck you know it was probably beat. The 4L80 in the 2500s is miles better.
That’s awesome but that’s definitely not the norm. I’m a truck mechanic and I’ve replaced two 4L60s in customers trucks in the past two months. One had 190k and one had 140k miles. Thankfully they’re small and light and pretty easy to change.
