OFFICIAL: 2015.5 (2015i) Discussion Thread

I think my six speed 09 Denali 6.2L shifts so smooth. I don't see what all the fuss is about. It's great. I have no complaints. It can only get better once all these vehicles have 8 speed transmissions.

Just got off the phone with my dealer. He stated the 8 speed will be so much smoother, I will feel a slight tingly feeling in my sac. I can't wait!

Settle down Felix ... after 26 GMT 900s in a row I'm pretty sure you're accustomed/addicted to it.

You get disoriented if your slip yoke doesn't clunk at least once a day.

2018 when the 10 speed comes out... everyone will diss the 8 speed and say that it shifted like a honda 300 4wheeler

That is not a clunk, its an audible transmission engagement notification LOL...

Sold my 2015 Yukon Denali to order 2015.5 Denali

Lol you think id keep buying them if the transmission sucked? I can feel a definite improvement from the 6.2L's 07 Esky to 09 Denali's 6 speed transmission. And also an improvement from the 5.3L 07/08 Tahoe and avy to the 11 Yukon I currently own. It seems like GM really fine tuned it as the years went by. I can only imagine what a '15 6 speed is like. I'm sure it's dialed in at this point. But I'm not gonna like I want the 8 speed when I do get one lol.

8 pages of debate over which massively excessive and overpriced piece of American iron we prefer.

Major first world problems.

 

[soulsea]

I know right ... all this on topic forum apt posting is schmultzing up our attention to derail.

I just want to find out when and where I can get my $8,200 off MSRP an 8 speed transmission Denali in the Dallas area =)

If they come out with a 10-speed in 2018, and pricing and discounts apply, and I have a customer that would purchase my 8-speed Denali, and I can depreciate a brand new 10-speed vehicle (if regulations don't change by then)...well I would probably do it if it makes sense.

No one ever said they should take a loss and move to an 8-speed truck. But if you're not in a hurry, and have a Denali on order and haven't received it yet, well what's a season or so to receive a newer variant?

Haha! My dealer told me the same thing after the factory guys left from training them on the new 2015.5

LOL I cant imagine any dealer I have ever met saying... "DUDE.. the new 8 speed FU%&$# sucks!!"

 

[motorwerks]

Let's just remember that this platform and ALL NEW 6.2l direct injection engine was designed to be mated to an 8-speed transmission and taller geared differential from the design stage. It was only due to development delays and EPA certification delays that these were released with the previous generation 6-speed.

The 8-speed Denali and Escalade with the newly configured differential and programming will give them an entirely different feel

you read my mind.

A guy I know who works for GM tells me that the dealer should be able to place an order for a 2015.5 on 9/4/14. While I'm probably not the first to have heard that date it's nice to get confirmation from another source.

[uscgto]

you guys think the 8 speed is ever gonna go to the SLT or the LTZ?

 

[fiatdale]

It will carry over before the next model change for sure. It will be the new standard, until a 10 speed comes out

 

[IrishTR]

Glad I waited and didnt pull the trigger early on.
