AISIN or 68RFE on new Ram 3500
What makes the AISIN six-speed automatic transmission worth $2600 more than the 68RFE?

One big difference I've noticed is my 2015 with the AISIN tends to hunt gears a whole lot, much more than the 68RFE I had previously. You pretty much have to manually select gears when towing. On the plus side, shifts are noticeably more firm and it just feels more solid all around. I haven't got the mileage or use to determine actual durability in any way yet. First and second forward gears are nice and low but, it's a little tall in reverse which can make the tight spots where you're backing uphill kind of tough. Keep in mind my truck is SRW so it's geared a fair bit taller than the DRW versions.
Use 4 low when backing. Use 5th gear when towing it will give you the same RPM's as a 4:10 in 6th.
I did a lot of experimenting with my 11 HO dually with 3.42's in 5th and 6th. Overall mileage towing in 5th was better than 6th and it did not downshift nearly as much.
