Of course Ram has a great trans, its a ZF that they put in most every high end Euro car sold today. It' a solid trans; we have ZFs behind the 1000 ci I-6s and 2000 ci V12s at work, and they're awesome. I had a only single complaint on my '14 Ram Laramie CC, and it wasn't the drivetrain, it was the highway vibration endemic to most every overly-stiff 1500 truck made today. With a 3.92 towing rear, it still got 21 mpg on a couple trips NY-OBX and back, only 1 mpg less than my '17 Silverado DC that I tossed within 6 month of buying brand new. Junk. (Edit: I love my '16, it's a completely different truck in every sense of it). If the Ram didn't have a highway vibration, I'd still have it; of all the guys with work trucks I know, Rams have the lowest maintenance; I still know plenty running around in 90s gen 318 and 360 trucks, one has almost 400k by now on original drivetrain. I had to yank the cams to redo the entire timing system in my '04 F150 last winter at only 150k... yeah they all have problems, just pick and choose which problems you'd rather have to fix.
The new HD GMs now have a new engine, with AFM for the first time, so there' sure to be learning curves with them. The old bulletproof 6.0 is gone. This should be interesting.
I can't bring myself to look at them longer than a few seconds, they're the most hideous things I've ever seen next to the Aztec. I guess they never fired those designers, just promoted them... what is it with Chevy's obsession with this Gotham-city Batman cartoon design shtick they've been doing for the last decade?
