Was wondering how these transmissions have been holding up.

Haven't read a lot of issues.

Because there aren't a lot of issues. An oddity posted here and there but it's a great tranny that overall has held up very well.

Good to hear.

Yeah you never hear guys complaining about durability. Sure you get the random post about issues but overall it looks like a great trans.

Who doesnt like a good, safe, reliable tranny, eh?

I think this tranny is way better than my 04 and 08 but I do have and issue with 3rd to 4th shift as well as some other with out years and even the 15s. It makes a grinding noise but it's one in very few. All in all I love my truck and my tranny

Both of my '13s have made a funky noise on the 3-4 shift, usually on heavy throttle application with a lot of shifting going on. I take it as normal and they both only did it a few times.

The 6R80 is 2009 until present; mine is at 340k kilometres, over 200k miles.

Forming company cabling truck; still runs fine., fluid and filter only maint work.

Several programming changes in the first years; a leaking wire loom gasket/grommet are the only issues I have heard about.

JLTD

How often are the fluid and filter changes being done? Are they dealer serviced or are you doing them in house?

I thought they were lifetime or when the trans was in for major service.
