HEY! That's my truck!
Stopped by the local dealer to pick up a brochure and noticed it said 8 speed I thought they are still a 6 speed Allison

This is mpg on a 2016 chevy 2500 crew 4x4 z71 with a six speed Allison Transmission 60-65 mph. Wonder if the new 2017 model with the 8 speed is any better?

Far as i know, the new dmax also doesnt have variable valve timing.
someone messed up that brochure big time. its still a 6 speed allison for the 17s

I did a 25 mile circuit at 65 and averaged 21.8mpg and thats with the front valance removed
I test drove one a couple weeks ago. It was awesome, obviously.
TC lockup schedule is aggressive and a bit odd. I found myself looking down a few times to make sure I wasnt in tow/haul.

i just got my 17 Denali 2 weeks ago. Sold the 15 with only 13k on her. I noticed instantly the insane injector rattle when cold and take off . I sent GM an email about it. They've contacted me and want me to take it in for a look. Oil pressure Varies a lot also seems like. 90 cold to 30 hot. Mighty big swing I feel like. Tranny shifts are very noticeable and sometimes slightly brutal for a guy with a light foot. I'll definitely keep you guys up to date on any changes they may make in my tune to possibly get rid of the noise. With many complaints they'll have a recall for it shortly
The drive is very nice, and very quite inside. The new motor does have what sounds like injector function/rattle at low speeds, I can hear it leaving from a stop until about 15-20mph. I didn't notice any deceleration rattle like others have mentioned. The truck throttle response and mid range is on point, and really does feel like GM spent some extra time on the tuning this time around. So far I'm very happy with the purchase, even though I was pretty attached to my LBZ. For those wondering, you can get these $70k loaded High Country trucks for $58k, only thing I didn't order was rear entertainment pkg . I have a post on DF, where everybody is keeping track of "Out the door" pricing.., for others to know what to bargin for model wise.[/QUOTE]

My lbz with 15-40 runs almost 90 cold to 35ish hot. 5-40 is 85ish hot to 30 hot. Sounds like that normal across all years?
