You're doing that on purpose, right? :)

Now I've gotta look into another possible option. And, to be honest, I don't do much highway at all these days so I could logically make a case for 4.10/4.30.

There's a possibility I could be towing on highways more in future though, but .... what if I'm not?

Thanks for that.
Well, you could change it to something else or put a taller tire on to tame the rpms to your liking.

Yeah I'm at the limit for tire height without trimming wheel wells and/or a lift. Not enough need for a lift really. For now the gears are the only real interest.

I daily drive an 06 Suburban LQ4/4L80e/4.10. We also own a 2020 Express 3500 passenger van with the L96/6L90/3.42. My wife drives the van daily to pick/drop off the kids at school. I think both vehicles are close in curb weight

I sometimes get to drive the van and I actually prefer the 4L80/4.10 combination.

The van will tend to downshift too often when I try to accelerate. The cruising speed is too low, like 1600 RPM. Once it's in the 2200-2400 RPM, then it comes alive.

The suburban cruises at higher RPM of course (2400 RPM), but it does so where the engine
is in the higher power band. That one will just go when I push the accelerator. Very rare to downshift.
Yeah I can vouch for those issues with the 3.42. Look forward to the better cruising speed and performance of the better gears. (3.73/4.10)
