Re: Looking at a new truck......

the 4.8 and the 4.8 is suprisingly weak compared to the 5.3 which is interestingly given on paper they are similar. That said both my suv's have the 4 speed and having driven many of the 6 speed versions it is a bit difficult to get used to the hunting that occurs. I like the 5.3 but not the biggest fan of the 6 speed.

I have to agree, although I have limited seat time with the 5.3L, for only a 10HP difference, when towing the 4.8L really works, I have a highway merge with a long 1/2 mi up hill run and unless I were to floor it (which I didnt want to do) I couldnt break 50MPH and 3000RPM's... Just had to hang at that speed till things leveled off, Makes me skeptical of this SUV's 6,500lb rating as I dont think I would want to go there since my boat is really only 1/2 that...

Last summer one of my suv's was in the shop for over three months while the inept folks tried to figure out what they did wrong when they installed a new computer. In those three plus months I drove every GMC and Buick I ever cared to drive. When no program vehicles were left, I'd get stuck with full size GMC and Chevy trucks. One week I had a Silverado with the 5.3 and 3.73's and the next I got what I thought was the identical truck model but it was just slow to move so I poped the hood and discovered a 4.8 under (but had 3.73's). Point being just as a daily driver the 4.8 seemed outmatatched by the heft of the Silverado. The mileage with the 6 speed's and the 5.3 was not noticibly different than my 4 speed 5.3 but of course mine is an suv and those were trucks so not a perfect comparison.

Re: Looking at a new truck......

To all thanks for the input and keep it coming. Although I am not commenting regularly I am take all comments and evaluating them.

I should clear the air a bit. I am pick a Chev becuase I work for a Tier 1 Supplier to the big three (Fords, GM, Chrysler). I work on design interior plastic injection components for this truck. I'm hoding off on pulling the trigger on purchasing this due to confirming the upcoming 3 year of work contract for the next generation of S-10. So until that materializes I am soliciting opinions on how other like their trucks. I have been a Ford man all my life, Uncles and Brothers work at Ford on the line. I have had the two vechicles currently for the last 10years. So it is time to trade in and upgrade.

I am going with GM, due to being able to pack closer to the building at GM Tech center and I want to drive what I design. Helps out on some of the interior for the 2012 Silverado..... So it's just a mater of pick what options and engine/trany I want.

I pull a 1991 Bayliner Trophy 2002 WA that is 5000lb when fully loaded. Toss in 4 kids and wife. then we are over the 6000 lbs added weight. I want to keep this truck for 10 years like my last vehicles so just want to make sure I get it right.

Fuel milage is a factor, with the 5.3l and 6 sp trany the fuel sticker says it will be better on gas than my current 2002 Ford Explore with the 4.6l.

My concerns are the aluminum block and the new style transmission... I know the suspension and body are good. It just the mechanicals.

I dont think you should have any concerns then, I've never heard of an aluminum block issue with the GM engine, the Corvette's were the first to start with them in 1997 (LS1) and the trucks have had them in some form or another for a number of years. IMO, the GM block is rather bullit proof, sure some make a piston slap at startup, but it goes away quickly- not sure if that is still a common issues, (our tahoe does it), no spark plug issues (ford) or need to replace 16 frequently (Ram Hemi).

The 6 speed started in the Escalade / Denali and 2500 trucks and slowly offered it into the 1500's, I think as of last year it was still an option on many silverado's. From driving one, it really seems to help the small block make the most of it's available torque/ HP range in a helpful way.

The cold start-up ticking like when you don't drive it for a day or when it is actually cold outside is still an issue but for both my 5.3's but it was fixed under warranty. I can't recall the cause at the moment other than recalling the bleed down but it was well documented and correctable. Even so the tick only lasts a few seconds and isn't detrimental as it sounds.

My 07 did it also. Like said about 3-4 seconds it went away. There was a TSB out on it then.

My guess then if you have family working at Ford you can get the Xplan or employee discount.Probably at GM also I know GM does it for family. That will save you some cash maybe.

Re: Looking at a new truck......

Let me preface my comments by saying that I am a GM person and that is all I own but I have driven and towed with all domestic trucks and vans for work purposes. My primary tow vehicle is an 02 2500HD Silverado with a 6.0 which has pulled large loads for most of its 170K+ miles with no major powertrain issues but since I do own a vehicle with the combo you are considering and have used it in work vehicles I will add my thoughts.

The 5.3 is an excellent motor and if you plan to do any towing, stay away from the 4.8 or any other small V8 or V6 options from any manufacturer. The small MPG savings are not worth the drop in HP and torque that result. Overall the GM 5.3 is one of the best half-ton truck motors at delivering good power and MPG.

I would not let the aluminum block worry you as others have stated however, I have experienced the oil loss/consumption problem that is prevalent in some of the newer motors with the DOD feature. The wife has a 2010 Tahoe that was purchased used so I am not aware of its complete maintenance history but it started using oil and especially after long trips with the DOD engaging often. The end result was the motor being pulled and re-ringed by the dealer which stated that is the only permanent fix for the motors that exhibit that problem. Apparently it's pretty random as many never have that issue and I feel it is from incorrect ring positioning on the pistons during assembly. Since then, we have taken it on several trips and it has not used a drop of oil. By the way, this is all covered under the 5yr/100K powertrain warranty so don't let it be a concern as the motors that have the problem seem to start showing symptoms around 20-30K.

Also, the 6 speed transmission shifts smooth and you are able to put it into tow/haul mode which holds shift points longer while towing large loads. I have not towed anything significant behind the Tahoe yet but I would hook my 20' Chaparral up to it with no worries. Granted, it's not as robust as those in the HDs but unless you're towing with it almost daily it will serve you fine. Since you are planning on towing, make sure you get the towing package on the truck you purchase. While you will need the receiver and light hookups, the addition of the transmission cooler will extend the life of the transmission more than anything.

No one wants a lemon but all brands are subject to problems. That's what the warrany is for. I think you will be pleased with the ride, comfort and power of the Chevrolet. As someone who has had the opportunity to use them all in the real world, GM trucks are my first choice.

Re: Looking at a new truck......

I have had one in most year models all the way up to my 2012. The 5.3 is fine if your going to tow occasionally but if there are ANY hills your gonna be sad. Definately get the 6.2 with the max trailering package. I pull plenty of heavy stuff all the time, skid steers, tractors etc. And to be honest I have grown to dislike the 5.3 with a passion while towing but the mileage is pretty good for a crew cab half ton. I have Duramax's as well and love them to death but with the miles I put on the 20mpg on the 5.3 is hard to beat. So good luck to you and I hope it turns out great for you. Btw if you have ever driven an older toyota with the 4.7, its a similar powerband. It loves to rev to make its power, not so much on the bottom end.

Re: Looking at a new truck......

I`ve got the 5.3 in my `05 Silverado quad cab 4x4. As far as the engine, I have had no issues towing. I tow about 6k lbs with my boat and trailer. And while I would not choose it if I lived in the mountians, for Indiana, it does ok. I did have to replace the fuel pump last week with only 70k mi, that was kind of fustrating.

I have been a GM man my whole life, but I have to say that I was not happy with them requesting a bailout. I like the fact that Ford did not and has been successful. I may be inclined to reward Ford with my business on my next purchase just because of that fact.

Re: Looking at a new truck......

Lets leave the bailout out of this. I am a Ford man that design Chevys for a living. Never owned a chevy in my life, and would like to know what I am getting into. Was raised a Ford man from the beginning. I know the design and testing side of chevys, its the same as fords to be honest. Their parts are designed on the other side of my cubical. It's that I would like people like me to share their experiences before I start making mine.

I am old enough to know everything in life is about politics, and hate it because it is. So lets not digress into that zone of discussion.

Re: Looking at a new truck......

Just a comment about a six speed trans. I have a toyota tundra with a 5.7l w/ 6sp trans and 4:30 rear end. I LOVE the 6sp trans! Never ever run out of power. Have owned ford with 4sp and Toyota with 4sp. 6sp is def the way to go. I could pull my 7000lb camper up hills at interstate speeds with no prob whatsoever. Terrible mileage when pulling heavy but don't care. Love the power. About 14mpg pulling my fishing boat n 11mpg pulling my ski boat. Always opt for more power. I'm not rich but dont care bout mpgs because for a half ton it is the best I have had yet! I say this after having a ford 1st gen tundra and a Chevy.

Re: Looking at a new truck......

I have driven GM trucks for over 20 years every day as a work truck, company supplied. As mentioned, you DO NOT want a 4.8!! The 5.3's consistantly go well over 200K without major troubles. Well, some have had tranny issues at the 180K mark. We run them as forestry rigs, and beat the snot out of them. Seems the harder we work them the longer they live, LOL!! 6 Speed autos are a different story in my opinion. I have not seen them fail, but I just cannot stand the constant shifting. I've had both the 4speed and the 6 speed behind the 5.3, and I'd take the 4!!

As my sig shows, I have a Dodge in the driveway, and I think it is the most bang for your buck, but you asked about GMC's.

Re: Looking at a new truck......

As for the alum block question...I would not worry about that for even one second. 5.3l stout? That is not the case. The 5.3 is no doubt on the lower end of hp when considering its competition. The facts are this the 2011 5.3l create 315 hp and 338lbs/tq. Imho that's pretty weak. When towing with a 4sp up a hill you will bogging or screaming. I do agree with oregoncruiser...the harder we work our trucks at work it seems the better they run....I don't get it but it seems to be the case! :)

Like I said I have two of the newer 5.3's now and had another a couple years ago but I agree that the 5.3's numbers seem a bit weak compared to the competition. They've had almost those same specs for years and years. Last night I saw a commercial for a GMC truck and they toubted the optional 5.3 liter and how robust it is and I feel like it is at least 40 hp and 40lbs behind where I'd expect.

Re: Looking at a new truck......

In my opinion, an automatic transmission will build less heat, and give you more miles when driven in a fashion that minimizes shifting. 5K is really not very heavy. Around here I can pull most hills in 3rd gear with my 4 speed auto, at around 3K RPM's and maintain highway speeds with little or no problem. Keep in mind I'm traveling in the Cascade mtns, so our hills are moderately steep.

My biggest problem with the 6 speed is that even on flat ground with no trailer when you try and accelerate the darn thing downshifts. On cruise control, forget it!!! I want my truck to get to the right gear and stay there. I don't think it's a BAD transmission, I just don't like it. My last 5.3 with the 6 speed was in a 2011, tranny was replaced under warranty at 36K. That was a $5700 bill. Just my $.02 folks.

.

I think I'm probably skewed a bit because here in MN there are almost no hills to speak of. I tow hundreds of miles each way sometimes and it's 99.9999% flat. The 6 speed Tranny really annoyed me when driving one of the crossover Lambda style GMC Acadias. Really heavy vehicle with a high tech, underpowered 3.6liter but try to compensate with the 6 speed. There is a reason they have the push button/manual shift mode. All the bad mileage of a V8 with none of the torque but somehow is rated at 5000lbs towing.

Totally see your point! U can't compensate for lack of power by adding more gears. Maybe that is why I like my 6sp so much just because it doesn't tend 2 shift up n down a lot and it really does shift very smooth. Even smoother than my wife's Avalon. I must admit that when I am pulling heavy and a decent size hill is before me I slip it over in manual shift mode which automatically kicks it into 4th gear which gives me all the power I need without having to press the accelerator to the point of downshifting. This only comes after pulling enough to learn my truck and how it reacts to what I'm pulling. Happy trails! :)

PS...just an FYI that's not really relevant to this thread but I used to get a little better MPGs prior to lifting the truck 3"s n up sizing the skids

Re: Looking at a new truck......

You should have no problem with a new 5.3.

There has been an oil consumption issue with them.
I know very little about it except that Chevy has a program in place to address it.
Involves a deflector being installed to keep too much oil from entering some area of the engine.
I would think that all the new engines have this installed at the factory.

I have seen the bulletin and customer paperwork on this at the dealership, but didn't read past the first paragraph, as I don't have this engine.


Tell us more about the new replacement S-10 line !!!! They are more my size.

Will it be a copy of the "world" Colorado like they have in Thailand?
Will we get the turbo diesel here?

I may have to buy my first new vehicle since '89.

Yeah, my wife has an acadia, so I know exactly what you mean. I gently tried to push her into another tahoe instead, but she chose the Acadia. It's cool, and drives nice. But it gets crappy mileage, and has no power to pull anything including the boat. She loves it though!!
