Chevy 4spd vs 6spd

Horsager Said:
I wouldn't buy a GM or Dodge because they took bailout money, I don't care how many gears their tranny's got.

They are actually half tons, with the 6.0 367hp 375ft/lbs, i have heard that the halfs unloaded are pulling better mileage than the 3/4, due to the AFM cutting down to 4 cylinder and now with the 6 speed, that they are better yet.I was impressed with the 3/4 ton 6 speed, but all i pull is my boat or my icehouse both around 3500-4000. I just figured someone might have had one or both of the trucks at one time, since it is tough to find a place where the two transmissions are compared. And as far as dealers go it is tough to find, guys who actually know what they are talking about. I have had several dealers tell me you can't get the 6 speed in an extended cab, other ones tell me that the 6.0 is the same in the 3/4 as the half, one even tell me it was an allison 6speed in the 3/4, so it must be one in the half, i didn't realize that buying a truck was this complicated haha.

"YES" the light duty  6 spd hydramatic tranny combined with the 5.3 active fuel management engine will give you better milage if you can keep your foot outof the engine,she rocks.

I bought an 09 Ford with a 5 speed automatic tranny.  The biggest difference you will notice probably isn't in the mileage, but with the shift points.  My last truck had the standard 3 speed with OD.  

It's a little weird at first getting accustomed to the different shift points in how you manage the pedal.

I test drove the 09 GMC and Chevy equivalents with 6 speeds, they too seemed kinda weird at first with the shift points.  As far as mileage goes?  Yeah, they are supposed to help overall, but you the driver will be the ultimate determining factor on that based upon your tendencies to either ease up from a stop or to stomp on it.

He may have the 5 Speed Torque shift found the 05' and up Super Duty (F250/F350). this will also be a 6 Speed starting next year. The F150s/Expeditions currently have a 6 speed.

Gotta admit that while I was open to a GM truck based on it generally getting better mileage, I have driven Fords for many years and the thought of buying a Govt motors truck was a big negative for me.  They may have been closer in comparison if it weren't for that and the roughly $7k less that I paid for a Ford.

Can buy a heck of a lot of diesel for $7k.  Roughly 37,000 miles of driving worth.

It is not the allison from what I have learned, Was looking at a 6 liter last year.  Its just a HD 6 speed tranny.  The Allison is only paired with the Duramax.  The only thing that turned me away from the 6.0 was the fuel economy.  Kept the 07 Duramax because of the 18+ mpg and pulling ability.  I am guessing with the 6.0 the best you will ever get is 12 to 14 going downhill with the wind.
