I have a DRW with Aisin and 3.42. I have grown to really like that gearing. I can lock out both over drives and run in fourth if needed and it is just under 2000 rpm at 60 which works well for my area of Hill Country in Texas. If i ordered a truck today it would surely have the 3.42. And, the lower gears of the Aisin in first and second do work better. My 14 68fre had a bit more trouble starting out. But, that trans failed twice before 15,000 so there may have been other issues that made starting out not work well. And when i am not towing i can fly down the road at 80-95 depending on the road and limit and the truck is turning low rpms still. We do have areas around here where the limit is 85 and at 95 i am in the slow lane trying to just stay out of everyones way as they tear past me.
