Why do you Cummins guys want more gears
I’ve heard a number of Cummins fans saying they are waiting for an 8 or 10 speed transmission before getting a new truck. Why? Does the Cummins struggle to get your trailer moving from a stop? Or are ...

More gears is better. I have driven a Powerglide, TH350,TH400, C6,700R4, The 5 speed Allison, 6speed Allison, and now the 10 Speed Allison. At each step, I thought it couldn't possibly get any better. I was wrong each time.
Nooo duuuuude....If you put your 4x4ord hat on and get enough torque rise out of a Cummins, a Powerglide would be the bees knees!
This whole thread is like an april fools joke gone sideways!
Exactly .... the need to downshift on hills is to increase the rear wheel torque. If the engine has enough torque rise to keep the power curve flat a downshift does absolutely nothing, other than maybe cause poor fuel economy. Going from a 6 to a 10 speed behind a Duramx is a big deal but with the Cummins it's not going to do much for it when it comes to climbing a grade. My point is pretty obvious to anyone who wants to see it ... I think you've got to have your eyes closed if you can look at how different the torque/power curves are of the Duramax/Cummins and not recognize that the Cummins does not need as many gears as its competition to make use of its power.
