Chevy Silverado Problems?

Recommended Posts

Looking for some advice from the GM truck guys out there. I'm looking at getting a used 4-5 year old full size pickup (gas V8 engine extended cab) with a budget of $15,000 to spend. Based on resale values and available choices, the best deals to be had seem to be with either a F150 or a Silverado (Dodge is not an option).

Right now I'm leaning toward the Chevy due to the fact that the extended cab space seems larger, but I'm not up to speed on the reliability issues for these trucks.

-Any engine / tranny or other issues to be aware of?

-Does the 4.8l get marginally better mileage than the 5.3l, or is it a wash? (From what I've read so far, sounds like the two engines have identical bores with the 5.3 having another 9-10mm stroke.)

-Do the interior controls hold up well (door switches, window motors, etc.)?

Appreciate any help, thanks in advance.

I bought my '99 2500 4x4 6.0L with the extra cab new, it has consistently got 19 mpg highway since day one, I replaced the original brake pads at 92,000 miles, the original plugs shortly thereafter, driver's side window regulator at about 125,000 mi. and now at 134,000 I'm gonna replace the guage cluster because the odometer display has shorted out. Other than that, I haven't had any problems out of it. All the power buttons and switches work fine, both front power seats work flawlessly and the thing will still holeshot in Atlanta traffic every time I want it to.

Oh, the daytime running lights burned out within the first 20,000 miles...I didn't bother to replace them, I hated 'em anyway!:applause:

(I have heard of way less mileage from the same drivetrain, but with the 4.10 differential gearing. Mine has the 3.73.)

The 4.8 will get 2-3mpg better than the 5.3, for some thats not worth the horsepower loss, for others it is.

Drivetrain reliability isnt a concern on the GMT800, the new small blocks are solid motors. The only real issue some of the early ones had is piston slap when they're cold. Its annoying and doesnt sound healthy, but it doesnt affect longevity of the motor whatsoever. Theres also been a couple of recalls dealing with the rear disk brakes on the pre 2005 trucks, you'll want to make sure those have been taken care of.

Never heard of any problems with power windows or locks... some folks have had problems with the speedometer sticking or quitting completely and the heated seats can be somewhat flakey. On extended cab and crewcab models the headliner can sag... its held up by velcro in the center and the glue on the backside of the velcro sometimes lets go.

Mine has a twich of the piston slap, only at initial start up & idling. Once under load, it stops. (The reason I've christened mine "Ol' TapTap"!) It hasn't affected the performance at all, and it's done this since 18,000 mi.

I think the speedo issues are caused by the intermittent shorting in the guage cluster. That has caused my odo to finally go completely, and it sometimes affects the fuel guage for a couple minutes at a time. I did some looking around, I found a guy that rebuilds & resolders new boards into the clusters and after core deposit, he sells them for net $110.

The only recall I've had with the brakes was a small re-routing of the lines to avoid wearing through at a point where they were contacting the frame.

I have 140K on my 1999 5.3L W/auto trans silverado. This truck has served me well and I would buy another chevy. I will say that when it was new it did have some problems but they got fixed under warrenty. Find a chevy that has been properly maintained and I think you will be happy.

Everyone Ive talked to has said the 4.8L and 5.3L get the same milage. The bigger engine doesnt have to work as hard as the smaller one, so the MPG is the same.

One of the biggest downfalls of these trucks is rear drum brakes. GM couldnt get the rear disc brakes to work, so they just went back to drums. Drums dont have the braking force that discs have and are more difficult to service.

GM had issues with the trannys on the early GMT800s blowing, but they made some changes on the later models that apparently fixed the issues.

yeah the rear disk brake problems is only on the half tons pre 2005 (when they switched back to drums)... our 2500's have a entirely different system (a much better system)

nah, the 4.8 WILL get better mileage, if it didnt they wouldnt bother offering it... usually in the area of 20-23mpg on the hwy, the 5.3 will get 18-21 or so (this is the pre 2007 engines... time will tell what the new displacement on demand motors get)

I wouldnt call the drum brakes a downfall... as a matter of fact their stopping distance is quite a bit better than the old disk brake system (and better than the new tundra's disk brake system... even with those HUGE rotors they like to brag about) Nothin wrong with drum brakes as long as they're doing the job.

GM auto tranny issues? What've you been smokin?

Not everyone wants or needs the bigger V8.

Drums brakes are old technology, they get the job done but they arent as good a discs.

Once again, WRONG.

GM has had their fair share of junk auto trannys over the years.

During the summer months I work for a concrete company and all of our trucks are Chevy 1500s and 2500 HDs, so I know a thing or two about these trucks. I spend as much time driving Chevys are I do my own personal truck, a Ford F-150. There are some things I really like about the Chevys and there are other things that just make me shake my head and wonder what the engineers were thinking.

i have had a few of these trucks and love them. stout driveline. the trannys are a bit weak especialy if you mod the truck for more power but in stock form they last a very long time.

the only problem with the rear brakes that i have ever heard of is the ebrakes like to wear them selfs out. there is also a tail gate cable recall on most of the 99 and newer trucks.

i had a 99 ext cab and now have an 01 hoe and a 03silverado with a few mods. i got the thing into the high 10's(1/4mile) with a stock driveline from a 2500truck and a big turbo. i am talking stock motor, tranny, tcase, front and back diff. i love these trucks.

Sure drums are old technology... old doesnt mean bad. As I said, the stopping distance is BETTER with the rear drums than it was with Disks.

Gm's had a few bad Auto trannys over the years (200R4 comes to mind) but none in the last decade. The current batch of auto trannys built by GM are the best automatic transmissions ever made... by anyone.

Just becuase they use them, doesn't mean that GM can take the credit for making them.:applause:

well, the allison is just one of half a dozen trannys in GM vehicles... all of which are pretty bulletproof.

and besides, Allison is owned by GM, so yes they can take credit for it. :applause:

That's like saying Jeep is responsible for Detroit Diesel's fuel economy.:eek:

Yes, they are in the same family under the corporate umbrella, and thankfully GM finally pulled their head out of their :applause: and started having their transmissions designed, built and serviced by their transmission specialists.:lol:

I will give my 2 cents (I own a 2003/2WD/1/2 ton)... Lets see...

--No engine or tranny problems at all. I tow a 6 X 12 trailor just about every weekend. Does just fine.

-- I can't speak for the 4.8... I got the 5.3. Plenty of power for what I need.

-- No problems with the interior controls...

--Just one recall, tailgate cables.

Overall, I have nothing but praise for the truck. I would not hesitate to buy another chevy truck. :applause:

Allison has been owned and operated by GM since 1929, and when purchased in 1929 it was a tiny company employing 30 or so people. GM basicly built allison into what it is today... I don't see how they cant take credit for the products allison builds. Thats like saying GM cant take credit for some of Oldmobiles successes over the years because they didnt start the company. :lol:

And I'd say detroit diesel owes more of their success to GM than chrysler, since GM founded and built the company, Daimlers only owned it since 2000.

So what you're saying is it took over 70 years for the PU side engineers to yell across the aisle to the Allison engineers,

"We don't have a clue we are doing, you mind giving us a lesson or two???"

Note: Chickenhauler is using heaps of sarcasm at this point, after having owned a few 700R4's that were worth more as scrap metal than as transmissions.:lol:

PS-I do have 3 GM products in my current collection, and all are doing quite fine, but none have a 700R4 trans. :lol:

No, I think it took Allison a good part of that 70 years to figure out how to build a auto tranny that would handle any kind of decent power... just like most other manufacturers. and for quite a few of those years anyone interested in buying a truck for work actually knew how to shift... so a HD automatic wasnt something all that nessesary until folks got too damn lazy to shift a truck.

And wasnt it you that was saying how tough your s-10s 700R4 was in another thread? :applause:

Allison has been building tough AT trannies for years, ask the garbageman.

Yes, but that was in a little S10-they didn't fare too well behind full size trucks that got worked-I mean, really, how can you pile into an S10?
