10spd operates seamlessly, rpm drop between gears is very small.
Couldn't be happier with its operation.
Hooked up to the race trailer this weekend, 28' trailer, Dirt Sportsman car, tires, tools, jacks, spare parts. No weight bars felt like a feather back there, cameras turn on with signals in center stack, very nice to tow with.
Can't wait to hook the 5th wheel, ISR adapter for the hitch being shipped on the 15th.

That was most likely the xmsn "learning" how you drive. As for me, Id LOVE to have the 10 speed, MUCH easier to stay in the desired RPM range.
I was sent thru e-mail a survey in regards to my 2020 GMC 3500. One of the questions was "What do you like most about your 2020 GMC 3500?" I responded, "The transmission" This is hands down the best transmission I have ever had in a HD truck. I just came from an Aisin trans in a Ram 3500 and this 10 speed is so much better in every way. A pleasure to drive.

I echo these statements.... I was skeptical, but so far the trans is seem less. Always seems to be in the right gear and have all the power available. Haven't pulled our toy hauler yet... gonna try that this weekend. 18k lbs loaded should give it a good test.

You think the 2021's will come out with Dana 60's in the front next :rofl
Why? Ford had nothing to do with this HD trans.

Good lord, why does everyone think that since Ford and GM collaborated on a 10 speed for 1/2 ton trucks that this is the same one they put in the HDs?
Do you really think the trans they're using in the half ton is capable of standing up to 945 lbs*ft of torque pulling 35,500 lbs of trailer with no torque management? Heck, the last Allison wouldn't even do that.
The 10 spd "Allison" has NOTHING in common with the Ford/GM 10 spd. NOTHING - except maybe the fact that they are both 10 speeds.
There's a video where the engineer who was in charge of developing the new Allison CLEARLY states this. I'll see if I can find it again.
I test drove a 2020 last week. I only drove it about 10 miles and I wasn't just completely zeroed-in on the trans, but I never even felt the thing shift. Not once. Muuuuuch smoother than my old 5 speed. I was really impressed with the truck. VERY impressed.
Having said all that, I am waiting for at least the '21s. Between the new body, frame, trans etc. I just decided that I'd wait at least a year for bugs to show up and be fixed. Ideally I'd wait for a 22 or so but at least with this truck, the motor is 3+ years old. My 2002 was the second year of production for the duramax and I've been absolutely hammered by injector problems. Not anxious to repeat something like that.

I wouldn't be so sure about that. When Mike L speaks transmissions you listen.

I was trying to find that one as well, but I couldn't remember which forum I read it on haha. Needless to say I need to stay busier at work.

Go to the 2:20 mark and listen to what the Assistant Chief Engineer for the "Allison" 10 speed says.

Mike L has one of the 2020 transmissions it is a ford built unit he has said so in multiple threads and so have other very reputable transmissions builders. The only thing allison/gm did was the valve body
