Imagine taking the 8-speed in the Denali and further flashing it with a performance tune! Check out the 8L90 performing below (watch the video also)...

Assuming I just ordered the LTZ today 8/22...I should expect the "updated" version? Or this only for Denali?

A list of the updates are as follows:
1. 8-speed automatic transmission (Denali only - lower 1st gear ratio, two additional overdrives, taller final drive ratio, new transfer case, new differentials)
2. OnStar 4G LTE Wi-Fi Hotspot with up to seven users
3. Hands Free Lift Gate (Denali only at launch, SLT being studied - wave foot under rear bumper to open lift gate)
4. Wireless Device Charging (Standard on SLT/Denali)
5. Optional Bronze Alloy Paint
6. GMC Intellilink now has an 8" color screen with capacitive touch feedback. (tactile feedback when you touch the buttons!)
7. Premium package now includes power assist steps
8. Sunroof now available separately
9. Rear seat entertainment now available separately
10. New enhanced security package
11. Rear bench seat now heated (optional)
12. new 20" chrome wheel available
13. XM radio is now 9 additional months (1 year total free)
14. More additional features may be available upon launch
There is a CHANCE that your order will automatically be held for the new updated models. Apparently, GM stated that August 14 was the last day to order the previous model. August 15-30 apparently won't have any orders accepted by the GM Connect system.

Interesting stuff...so I may get some of the new stuff but not all. I'm ok with that.
It was odd that the GM customer service person took forever to look up my order no then came back asking for additional info including the dealers name. I also emailed my salesrep and did not get a reply. They've always been prompt with replies. It's concerning to me since they wanted my trade in right away so I let them have the SRX 3 weeks ago. Not looking forward to another month at least having to drive my 25 year old car!! Guess it'll be worth it if we get a 2015.5 with the updates.
Any idea what the final drive ration will be? It's 3.42 currently, correct? Any thought as to whether the tow rating will change?

Not sure. On the Corvette with the 8L90, 1st gear is an aggressive 4.56:1...that'll make it scoot from a green light!

I'm guessing a 3:21 ring.
My Denali is scheduled to be built this week. Whether it's built with the 8 speed will only be determined when it shows up. Fingers crossed that I don't have to wait into the winter to get one.
If's its a keeper with the 8, I'll let you know what gearing it comes with.
