Looking at a 2019-2020 crew cab 2.7 4x4 as my next truck and came to ask about common issues.

I have read some on iwes and the 10r80. The 2.7 seems to be the way to go if you don't need a lot of towing.
I heard the main issue with iwes you just tsb plug the vacuum. The 10r80 i really am not sure.
Can anyone chime in with further info?

I don't really want to end up with a ton of big issues.

I did have a 15 2.7 for 60k and the only issue was an aux transmission pump.
