10 speed. Your opinion?

If you have a 2020 with the 10 speed. What is your opinion? I'm on the fence on purchasing the new 2020. The old school has always been don't buy the first year of production.

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.

I am happy with the 10 speed as well. I had some surging going from 2nd to 3rd early on, but it smoothed out aftera few hundred miles. Love the way it pulls the toy hauler.

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.

Butter smooth. After having 2 6 speeds, this is a huge difference. Very happy with mine.

Count me in the same group as the others. The 10 speed has been great to drive with. And mine is still learning, so it's getting better and better each time.

Shifts are hardly noticeable and it's smooth as silk!

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.
