I would be very interested in this.
I know that with the older diesel engines they put a higher gear ratio in to
balance because the power band being lower in the rpm range compared to a
gasser.
I do know that the Ford can be had with 3.73, 4.1, and 4.3 as a gasser but
only 3.73 and 4.1 with the diesel. The 7.3 powerstroke uses the same manual
tranny as the gas engine. I dont know the specs on the auto. The new 6.0
liter Powerstroke (560ft.lbs of torque baby :) has an entirely new tranny.
The GM duramax also has a different tranny from the gas drive train, but I
read this was because of the power output.
Hmmm, ya know that 6.0 liter power stroke sure does look like it would fit
into a defender engine bay ;)
