New Sierra 6.2 Shopping
 

I've been on the fence of possibly purchasing a new truck. I currently own a 2012 Sierra SLE extended cab NHT 6.2, with just over 60K miles. I love the truck but the northeast winters are killing it, frame looks terrible with surface rust and the rear drivers side fender I've noticed is just starting to bubble. It needs tires and brakes as well which isn't a big deal but it adds up. I figure it might be a good time to get rid of it before getting into rust repairs and other miscellaneous maintenance items.

Anyways I'm looking at a new 2017 SLT Double Cab Z71 with the 6.2. The MSRP is $51,205, which is about $10K more than the MSRP was on my current truck when I bought it in 2012 (Ouch!). How much off the sticker should I be able to pick up this truck for? I hear of some people getting as much as 20% off the sticker price. I also need to factor in my trade and hope to get avg. NADA pricing. Is there a better time to buy than now? The '18's are on the lot so I figure they have got to be giving decent deals on the '17's

How is everyone liking the new 6.2 with the 8spd vs the NNBS 6.2 with the 6spd?

I just bought a 17' GMC SLT 3:23 6.2 Z71 8-speed yesterday. I had a 2010 2wd NHT 3:42 GMC Sierra prior. I'll tell you exactly how I feel about it. I regret getting the new truck. I miss my old truck. In particular the way it drove. This new truck feels like a turd at part throttle. The old truck felt eager to go anytime. When you get on the new truck going down the road it feels pretty good but there's no comparison at the tip in power my old truck had. My old truck was stock with the one exception being it had Kooks long tube headers and high flow cats. I miss the sound and power. On the flip side, the interior on the new one is lightyears ahead of my old truck. It is way more comfortable, much quieter, gets better mileage, and has an abundance of tech goodies. Also, I will add that the HD Denali front I put on my old truck looked a thousand times better than any new GMC that I've seen. I got 5500 knocked off the sticker. Too me that's just OK. I didn't push them and can only blame myself on that one.

8 spd in my pinion is not good. I have a 16 ltz 6.2 8spd and a 16 lt regular cab 5.3 6spd. I don't even touch the ltz

There are still problems with some of the 8 speed transmissions so you are taking a gamble on that. I also read about a lot of electrical problems. I believe the new promotions come out next week. I ordered my '15 and got around 17% off sticker in April of that year. Dealers are definitely trying to move what they have left on the lot towards the end of the year, but it's slim pickings and dealers are reluctant to trade with another dealer to get you what you want.

When i make the jump, itll probably be a used one. let someone lease it for 3 years and ill pick up the used model. The aftermarket should be solid and the tech behind all the new stuff should be ironed out. These new trucks are so expensive because they have every option. Here in NY, April/MAY had 20% msrp for LT models thats a decent chunk

This is exactly what a tune fixes.

From a "normal driving and how the motor reacts to throttle inputs" perspective, it feels like you took out a v6 and installed a big block

Also, the l86/lt1 is up there with one of the best sounding v8's ever built once you uncork it. I rented a camaro for a week and every time I cold started it I couldn't believe I had the same motor lurking under the hood of my truck.

Laura GMC, either fly there and drive home, or atleast use their prices to negotiate with local dealers.

They won't give you much for trade-in, so would just need to sell private party.

I got 10k knocked off my 2017 GMC CC Denali 6.2L/3.23 8 speed 2WD.The 6.2 is no joke!!! Both my brothers have 2017 CC with the 5.3L/3.42 6 speed and there is a lot of difference in the power especially on take off.

I would wait and avoid the 8 speed myself. I had one and it was junk lol... Gm never fixed it so I sold the truck. The 10 speed is coming and is currently behind the 3.5 Ecoboost. I have driven a few now and they seem pretty nice... plus after a year the big Ford forums aren't littered with "my transmission sucks" like with the 8L90e. This is all provided GM doesn't screw it up for themselves... which they may very well do lol.

Its crazy that so many people dislike the 8 speed on the trucks.

It’s the same trans on the camaro and corvette, which I drove, and it is incredible.

There has to be a way to make it perform like it does in those cars.

It’s a pretty amazing trans, I’m thinking in the long term the aftermarket will do some great things with it.

Incredible pile of shit... yes i totally agree. Wot it shifted okay... but I'm.sorry I don't drive wot all day long... or at all like a performance car that is 2000 lbs lighter will be driven. Now it's been superseded by the 10 speed which all the Vettes and Camaros will run .. so why bother lol. Wouldn't surprise me much if gm drops the thing completely lol.

Yeah but the trans as a solitary piece of hardware is great imo. Just think GM really screwed up the tuning and electronic controls of it.

It’s not like a problamatic trans for everybody either. Which leads me to believe there were some manufacturing defects a long with the worlds worst tuning.

Seriously I think GM has some of the worst factory tuning out of any company out there. It’s amazing how good the hardware can be and how bad the end result can be.

Oh I agree... it's why I made the statement I did about the 10 speed. The 6R80 in the Ford shifts pretty good...and it's basically a 6L80e as an example. The 10 speed may be the same way.. shift great in Ford's and then Gm will make a mess of it with their shitty tuning. I said years ago they should fire whatever clowns they have write their maps and hire the Ford guys lol. They aren't perfect either but it's leaps and bounds better than the rubbish gm does. That said tuning did not fix my 8 speed pile and gm wouldn't put a new trans in the truck so I fixed it by unloading it lol.

I drove my brother in law's 6.2 sierra Denali 8 spd and was not impressed. Definitely like the 6spd in my 5.3 Silverado better.
