Hello I order a 2022 Laramie in Mid-June went with the HO engine & Aisin Trans from my research seemed to be the way to go but still don't have it so no real experience yet. we will be towing 350M loaded with toys but may up size trailer later hope this helps

I’ve had two HO / Aisin combos. Low speed shift pattern can be a little funky at times. Other than that it’s fine. I’m towing around 14k loaded for a long trip. Towing much more l would probably go with the 4.10 gears. I have 3.73 and will lock out 6th if running in the mountains.

AISIN - 100%. If you have never driven a Cummins before, all a little lagging from dead stop and not instantly responsive. This is because the Cummins will shread a trans otherwise so there's heavy torque management programming and the drive by wire throttle arc intentionally delayed. As was previously said the AISIN has some funky shift behavior at times, but way heavier and more capable than the Chrysler box. I recently drove a 2021 HO and they have done a great job smoothing the programming compared to my 2015. I'm anxious to see if rumors for the next full generation revision of the heavy trucks delivers one (or both) of the new transmissions behind the Cummins with more gears!

I just had a PCM update to my RAM and I like the smoother shifting of the Aisin since with a couple of exceptions - mostly hard 3rd gear shift while accelerating and then having to back off to brake. But, the vehicle is still 'learning'. Below is what I posted on the Cummins forum a couple of days ago.

"I have noticed the shift change though mine has been less harsh. When I head off to work, within a mile, I have to make a sharp right onto a 17 degree climb up a hill. Traction isn't the best with morning dew on the roads. Truck used to really bog down by an early shift into 3rd and then mis-fire trying to accelerate up the hill until I got to the top and could back off the pedal a bit. That has smoothed out considerably and seems like the shift into 3rd is delayed a bit."

I have a '19 RAM 3500 with the HO, and Aisin tranny. With what the trailer you are looking at is weight wise, you want the heavier duty tranny. I personally don't care for the way the Aisin shifts (have the most recent software update), as I need a neck collar at times, but if you are getting the RAM, the smaller tranny is going to be working a lot harder.

I've had the SO diesel transmission combo and have been more than satisfied pulling at my weights (~15k).
My '14 Ram had 100k miles, pulling the trailer often, in the West coast though many mountains. Not a single issue. Only thing I didn't like was the 3.42 rear end.

My '21 has the SO and 68RFE as well. Feels better with the 3.73 gear and the transmission shifts great; no complaints.

Since you're looking at DRW, with 4.10 rear, I think either motor/trans combo will serve you well.

The 68RFE is a bit smoother, but many swear by the reliability of the Aisin.
