Saw an '05 2500HD CC on a Chevy dealer lot today. Has the 8.1/Ally in it. Had a much smoother ride than I expected.

 

Love the drivetrain and the truck. However, it is a cloth LS interior, a step down from my current 1500 trim. I can deal with the cloth, but my wife and I would greatly miss the heated and 10-way power seats. It would have been a driveway/garage queen, and used mainly for towing.

 

I think it was overpriced, and they sneered that my truck could be of any value near what I thought it was. The usual stuff. Truck has 85K in the clock, and dealer has all service records. My only reservation about the truck was no info or record of transfer case inspection or work.

 

If anyone is interested, check it out at alexanderchevydickson.com.

man...my 6 litre isnt much better...the absolute best i can get 12.5 MPG and seen it as low as 7. and my tire size/speedo is dialed right in too. our older work trucks with lq4 are the same also, we a couple 8.1's too the mileage is pretty much the same dude...

just because its a 6 banger dosen't mean its going to get good mileage..the key is a good balance between the engine and weight of the vehicle...the v6 is underpowered in a fullsize and the 8.1 is overkill

Think you read that wrong. He means the 6L V8. I have one that also gets about 12 MPG at best, so I know where he is coming from.

My 03 LS 2500 HD 8.1 Alley get's 12.9 highway @ 80 mph unloaded & 10.5 pulling 10K trailer. It is a driveway/garage queen with 28.5K on the clock and mostly used for towing an enclosed car trailer or, 32' Cabin cruiser with twin 350 cu in Chevy engines. This truck "Floats like a Butterfly & Stings like a Bee"! If I want gas mileage, I drive one of my cars!

My friends 8.1L crewcab shortbed with 3.73's gets the same mileage as my 6.0L crewcab longbed with 4.10's. For how many miles I put on it a year, I should have got the 8.1.

Crew cab, short bed with 3.73 rear and 245-75-16 LT tires. Only mods are a good PCM tune to 89-octane, Mobile-1 and K&N intake. I failed to mention, if I drive unloaded with cruise @ 60 mph hwy, (no stop & go) it has averaged 16.5 mpg.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      By Greg3160 · Posted

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
