New Chevy truck question

[brittsnbirds]

I am thinking about replacing my current tow vehicle ('03 Chevy 1500, 5.3 extended). I think I have decided on a 2010 Chevy 2500 HD with the 6.0 (gas).

The question that I have is are they putting the Allison tranny in the 6.0 gas trucks? I stopped at a Chevy dealership yesterday but they didn't act too sure. They looked at each other as if the didn't know then said Yes. I know Chevy is putting a 6 speed in them. The tranny has the Allison style toggle shifter on the selector but am unsure if it is an Ally.

If Chevy is putting the Ally in the 6.0 gassers that would be a no brainer for me!!

Appreciate any info.

I have a 2008 chevy 1500 Vorteck Max witch is an HD with a 6.0 gas and it has the heavy duty tow package and it came with a 4 speed heavy duty auto trans. I am waiting for a phone call back from the Chevy dealer as I write about your question....

Thanks rockwood for your quick response. I have a cousin that bought an 09 1500 2wheel with a tow package. He has a 5.3 and it has a 6 speed. It has the toggle shifter as well. Thinking it was the Allison I pulled his build sheet and there is no up charge or information about the Allison on it. I suspect it is just a regular tranny.

Ok here it is, with a 2500 HD (GAS ) engine 6.0 the only trans you can get is an automatic 6-speed heavy duty as standard equipment, but it is not an Allison. The Allison comes stardard with the Duramax engine. All GM Truck with an automatic trans are 6-Speed now, even the bottom of the line 1/2 tons. There is no longer a 4-speed heavy duty automatic trans like the one that is in my 2008 and form what I have been told, there is no more standard trans made from GM. Now I didn't ask the question but I think they toke the heavy duty automatic 4-speed and made it a 6-speed....I hope this helps.

Yes sir it does. Thank you.

Before I read your response I got onto Chevy's site and built a HD 1500. Then I built a 2500 and attempted to put the Allison on the 6.0. It would not let me. So I'm back where I was. However I do know with the Duramax and Allison your talking about 10,000 bucks more. Thats with the extra battrey size, alternator, block heater etc.

So the jury is still out.

Thanks again. Obviously the Chevy dealership I talked to is going out of business for a reason, they don't know their product!!

Sorry it toke a while, I had two new truck saleman doing the research. It's funny how salesman are out there selling products that the know noting about. Today I called the dealer where I bought my TT to see who suppied the frame for my 06 Rockwood, I talked to a new RV salesman he had to connect me to the service department because he did not have that info....so is it a lack of training or is it that they just don't care...as they say GIVE ME YOUR MONEY and you can deal with the issues youself.

May want to consider FORD f250 v10. I understand mileage may even be better than the 6litre

[brittsnbirds]

I've thought about the v10 Ford. Wife's uncle pulled a BIG TT with his. That thing was a pulling machine. He got 10 mpg whether he was hooked up or not. It did a very good job. But I've always done the Chevy thing.....however now that they are partially owned by uncle Sam. I may have to swing the other way.

How many Cubic inches is the v10?

[dezolen]

It's 6.8 liter. Mileage is no worse than the Chevy 6l.from what I have read. We went from 2005 Chev Tahoe to the Ford. Very happy with performance pulling our 12,000 5th wheel. Averages 9.5-10 mpg towing it. Has almost the same tow capacity as the deisels. Engine breaking makes downhill stretches a breeze. Have not needed any aux stuff such as air bags, trail air pin as I can barely tell trailer is behind me.
Our fleet has all Fords and majority are excellent. Found better deals on the Ford and many features were optional on the Chev such as tow mirrors, hd hitch, and a few other items. I think it is the best bang for the buck for us as we don't put alot of miles on it(8000 per yr) and use it to and from work apprx 12 miles per day

Made a trip to the Easten shore, towed with the 2008 Chevy 6.0 gas average 10.5 mpg. The truck has less then 7,000 miles on it. With out towing so far I have been averaging 17 to 19.8 mpg. This is what the Drivers Information computer system is telling me and how many gallons I use. So far the info it has been giving me is good with in a gallon + or -. but this may depend on how much gas I force into the tank after the pump shuts off. Compared to my old tow vehicle the 1997 3/4 ton GMC Suburban with a 350 I get the same as the Suburban while towing but better mpg then the Suburban with out towing. I averaged about 15 mpg with the 1997. The only thing I don't like about the new truck is that it has a 26 gallon fuel tank, the 1997 Surburban has a 45 gallon fuel tank but I did have to dig deep in my pocket when it came time to fill it. The most it cost me to fill it when prices were sky high was $105.00 and it wasn't empty.

I have both gas and diesel 04 chevys with the allison transmission.
The gas is the 8.1 with a 4.11 Rear end and the diesel is 6.6 turbo with a 3.73 RE.

Both are 330HP, but the torque is way diff. Diesel is 550lbs and the 8.1 is 450lbs

Spring for the diesel if you tow a lot. I pull a 36 foot 16000lb 5r like at 75mph like it aint back there with the diesel
