just noticed on my local dealers website he has 2 chassis cabs listed

i went and looked at the window stickers and noticed that they are both 6 speeds with 4.10 gears

i did not think that g-56 came with 4.10 gears

man these things will sure turn some rpms wont they

 

i thought the 4.10 was all the cab/chassis came w/

 

thanks for the info i was not aware of that

with that combo that thing should pull like a frieght train

 

I believe the automatic for the 6.7L is a 6 speed also.

 

the g56, aisin automatic, and 68fre are all 6 speed trannies
