    I may be purchasing one of these in a year or two & wanted some feedback from people who have owned both. Is there a considerable amount of difference in performance? And is there a considerable amount of difference in fuel mileage? I have heard the Aisin, that comes with the HO, needs to be serviced more often. If they are running the sale on HO's like they are now when I purchase, it's almost a no brainer to go that route.

    No trans tuning not yet for the Aisin. Torque management doesn’t allow either engine to put down the torque that the engine has. It’s less likely to give ya any trouble over the 68rfe.

    Depends on what you are hauling and the price difference. If you are near the limits of the truck fairly regularly, the HO might make sense. If it will be a grocery getter with an occasional 10,000 lb trailer haul then the SO might make sense. Heck if its the latter a 2500 also makes sense.

    Given your time frame the new transmission should be out, and I hope it's a winner. The Aisin is plenty stout, but it's sort of a stumblebum in operation. As mentioned, Ram's torque managenment is very heavy-handed. I hope the next trans allows them to tame that down, as it really handicaps the Cummins.

    I Love my 2021 3500 LB DRW HO CTD 4X4
    Tow a 17k 5th wheel.
    My 2018 2500 SO CTD was up to the task, but sure footedness was lacking. This one has 5500 cargo capacity and 34k towing.[​IMG][​IMG]

    Pulling 13.5k 5th wheel now with my 2500 gas which is at it's max. Want something that can handle that & more if we upgrade trailer in a few years. I would like to wait to see if they come out with a heavy duty Asin/ or Torquflite 8 speed for these, so hopefully they will be out in the next year or two. I am not opposed to the HO unless it just gets 2-4mpg less fuel mileage. For what they are running now it would be well worth the extra money for the more torque & better transmission.
