13 speed for 15 speed
can I swap my wore out 13 for 15 speed with out too much trouble
Is this a good question?
the difference in 15speeds is one is a direct and the other is a 15 over.a 15 direct has 5 low gears and the top gears are a 10 speed. an over has 5 low gears and you split the top like a 13speed i have driven 15 direct 15 over 13 speeds.i'll take the 13 speed over the rest.why do you need 15 direct unless you're pulling heavy.a 15 over will be 100mph plus truck.
zachary,you won't be a driver for very long doing this,probably have to drive in 13th to be reasonable,but what will it do for pulling hills.i think there might be a reason why eaton went away from this transmission.better with 13 and if needed 18 speeds
Check your final ratios, many 15s are .86 overdrive. The only one I was ever around went 1.2 million miles with only minor maintainence. 1987 COE IH with 425 ataac cat. With 3 .73 rears and 24.5 low pro rubber it turned 1500 @ 60 mph if I remember right. Nice ride!
