mpg difference between 6 speed and 5 speed
#2
little to no difference.
final drive ratios are very close .75 in the 5-spd .73 in the 6-spd.
6-spd has closer shift points and less rpm drop that helps with towing..
rear end ratio (3.55 or 4.10) and what you do with the truck will have more of an effect on fuel economy than what trans is in it...

I agree. It depends on how you drive the truck. My overhead computer shows my average at about 16.7mpgs... but I have RV275 injectors, Banks High Ram, Fleetguard AH19037 BHAF, and a larger exhaust.
If I keep my foot out of it on the flats I can see numbers between 19 and 22, and I'm running the NV5600 6 speed.

Originally I assumed a manual would get better fuel mileage too, but when you look at the final gear ratios, overdrive on an automatic is actually the best of all available transmissions at 0.69.
I got my info from here, which has handy diagrams of all ratios for all transmissions with all rear-end ratios:
Gear Vendors Under/Overdrive Dodge/Dodge RAM Final Drive Ratios.

My 2000 has a 5 speed with all the right mods for mpg and my calibrated scangaugeii says I get around 26-27mpg on the highway when I keep speeds at 58 in 4th gear.
