OT Newer chevy truck problems?

[71Rat]

Hello all
This summer or sooner I am going to try and get a 2001 or newer 2500HD. I was wondering if any of you have heard any major problems with these trucks? I was told that they had piston slap, and at school i went onto our computers and looked up the recalls on them and other customer interests. so if anyone has anything they know about these trucks or has one and could tell me a few things about it.


Thanks
Rat

Rat, Which motor are you after the 6.0 or 8.1? I work at a Chevy dealership, if you have anymore questions.

my dream truck would be an 8.1 with the allison but i would take either the 6.0 or the 8.1.... i have heard that the 8.1 mpg is not that bad, but the hard thing is finding one in a truck that isnt beat that i can afford. but i would like to hear the pros and cons of both engines if you have the inside, and the allison vs the 4l80E if you could.


Thanks a lot
Rat

Depending on how much you tow/haul with the truck is what is really going to determine what kind of milage you will get, I assume you are buying a 4x4? If so a 6.0 is at best on a good day going down hill with the wind will get maybe 14mpg when you hook up a trailor with a little bit a weight you will dip well below 10mpg. Don't get me wrong I believe it is a solid engine. With the 8.1 you should be around 8 to 10 mpg unless you really load it down. Both trannys are pretty solid but the allison is heads and tails above the 4 speed imo. The way you can feel it downshift when you are pulling a heavy load is cool as hell. Those trucks are out there (8.1 & allison) try to find someone who might of pulled a boat or something like that, you know not a farmer or construction worker(no offense but the boater is more likely to treat it as a toy than a tool) Have you thaught about a duramax?

azskso- thank you. i understand were your coming from with the boat towing, i was also looking for ones that havent been plowed with. the gas milage is not a major concern for me because my tahoe now gets only 13 on a good. yes i am also looking for a 4x4. Do you know of any problems with either engine? i just mainly want to know what i should look for when test driving and looking at one.

Thanks a lot

Lots of great info on that site

Regarding 'piston slap' or 'cold start knock' - I have had that on my 2000 5.3l GMC since it was new. After 106K trouble free miles it is fine.

There are no real problems with these trucks IMO.

plan for the future and buy a duramax with the allison transmission. It may hurt the pocket book now but when you try to trade it in you'll thank yourself for buying a diesel.

Gas vehicles don't hold there value as well as diesels

I've got a 2000 GMC Sierra 2500HD 6.0L auto 4x4. It does rattle a bit when cold, but other than that she is pretty quiet and runs good. As far as the gas milage I get 15 to 16mpg when I am not hauling and 12 to 13mpg when I am (I haul a 2 horse bumper pull). I am surprised you guys get so much lower mpg... I've gotten close to 17mpg on a trip with it before...
