I don’t like this 10 speed trans

[Toomanyhobbies]

I like my new ‘22 burb rst 6.2 a lot. But I don’t like this trans. I feel as if it slips in a minor way under medium acceleration, but what I really don’t like is the way it holds rpms/pressure. Going downhill I find myself constantly pressig the “N” button because it’s holding the revs at around 2k and I have to press the gas to get the 6,000 lb truck to roll down a hill otherwise. It also holds the revs too high/long after giving it enough gas to cause it to downshift. I never thought I would say it but I much prefer the 4l60e. Drives without a computer nanny...

Sounds like Hill Descent Control. It's to keep the vehicle at or under speed so the brakes aren't needed to maintain it at that speed. This way, they're not heated and are more ready/effective should they be needed.

It also holds the revs too high/long after giving it enough gas to cause it to downshift. I never thought I would say it but I much prefer the 4l60e. Drives without a computer nanny...

Sounds like typical GM slow/gentle/soft tuning. Having so many gears, it slowly and softly climbs back up through all of them until it eventually reaches the ideal gear for the speed and load. Their tuning kills many transmissions prematurely, especially those driven mostly in city/suburban settings, due to all the extra shifting.

When I bought my 2017 Honda Accord V6, I soon learned about "grade logic control." I'm sure it's not exclusive to Honda transmissions and what you're describing sounds exactly like it. At the end of the day, I got used to it and figure it's helping reduce wear on the brakes.

Grade Logic Control
To reduce gear "hunting" and unnecessary shifting, Grade Logic Control and Shift Hold Control systems are integrated into the shift programming of Accord automatic transmissions. Grade Logic Control alters the 6-speed automatic's shift schedule, reducing shift frequency while traveling uphill or downhill. Using inputs monitoring throttle position, vehicle speed and acceleration/deceleration, Grade Logic compares the operating parameters with a digital map stored in the transmission computer. When the system determines the Accord is on a hill, the shift schedule is adjusted to automatically hold the transmission in a lower gear for better climbing power or increased downhill engine braking.

In the K2XX the feature is called “Grade Braking”. And it almost acts as if the transmission is engine braking as it descends down a hill which in turn holds a slightly higher rpm “coasting” down hill controlling vehicle speed without using the brakes.

Similar to what’s described above.

Also; In the K2XX you can choose to have this feature active or disabled. I’m sure you can turn this feature off in the ‘21+ models.

I am going to go look at disabling it now in the settings and will let you know.

On the topic of brakes, what kind of brakes do these trucks have? The module under the hood is so complex I cannot figure out what I am looking at.

Thanks!

Have you or anyone else noticed when the vehicle is cold that the tranny stutters when taking off? My wife’s Tahoe with the babymax has been doing this since we got it and I figured it would work itself out of the issue, but now with little over 2k miles it is still doing it.

 

[Mannix2019]

I have a 2019 and can disable the Grade Braking by pressing the Tow Mode button on the gear shift and holding it for 3+ seconds. Doesn't stay off, but I only really notice the braking on really long downgrades driving through mountains.

I had a loaner F-150 with a 10 speed, I hated it too.

I looked up the Pulsar and looks like its only for trucks, not the SUV.

HP Tuners requires purchase of an unlocked TCM then tuning credits and is expensive.

You might try to just reset the current TCM and see if maybe its in some weird cycle. Here's a link I found but I have never tried: https://www.replicarclub.com/how-to-reset-transmission-control-module-chevy/

You might even write some of it off to the TCM just learning your driving style. Mine used to hunt for gears when I first got it but after some more than spirited driving, it was fine and the Lew Tune made it that much better.

This procedure is for the 4l60e so I doubt it works for these high tech trucks. I am almost due for my first oil change so i am going to ask the dealer to do it.

And yes cevenson23 I have noticed the trans feels like its slipping when I give it light throttle and it does not have to be cold. The whole truck operates better the more gas I give it actually.
