Hi guys, just bought a new 2022 Silverado RST Z71 with the 5.3L and 10 Speed Transmission. Only had the truck for a few days but noticed if I don't take off under heavy acceleration there is a lag in what seems to be the 1-2 shift. It shifts but the truck basically acts like it bogs down and hesitates on the initial shift. All others shifts seem fine only the first shift has this bogging and takeoff with more throttle seems to resolve this.

 

Just curious if anyone else has experienced this and if its normal transmission learning cycle or maybe related to this new update from GM.

If anyone else has experienced this or has done the update above please let me know your experience.

 

Thanks

Man I love that color!!  Welcome & Congrats on that truck!!  How many miles?  If you've only had it a few days, give it a few hundred miles for the tranny to learn your driving habits.  If it still sucks, take it to your dealer to get fixed.

How is the tranny operation now? Has it "broken in?"

Nearly 500 miles in and still the same. Really just the 1-2 shift bogs the motor unless you throttle into it pretty quickly.

Guess? You are feeling the Torque Control. Pulls timing to soften the shift.

Have the same with our 2023, called dealer and they said they wouldn't do anything till I put 1000 miles on her.  We have about half than now and its still present.  Doesn't make sense imho that it would "correct" itself.  Rest of the shifts are butter.

My dealer called me on Saturday and basically told me the transmission is learning for the first 2000 miles. He recommended I wait till then and see what it's like. I'm at 1100 miles and it does seem to be getting better. So I'm hopeful it will work itself out.

 

Good luck

I am having the same issue with my 2023 GMC Sierra 5.3 with the 10 speed transmission. Shuddering whenever truck is around 1000 rpm. It seems as if the truck isn’t sure if it should shift up or not. I waited a bit to see if it would correct itself, but now at 9000 miles I’m still having the same problem. I brought it in for my first service and mentioned the issue. I was told it was the new 10speed transmission and it was fine on a road test. I’ll be bringing it back in again because it’s not right. For 60k+, I’d expect a better product.

After 9000 miles there should be no shuddering from the transmission. I have the 5.3 with 10 speed in a Trail Boss and have never had any shuddering.

I would change the trans fluid to a better quality fluid at the first sign of a problem. 100% synthetic Amsoil, Redline.

Using non approved fluids will void the warranty.  Neither Amsoil nor Redline produce any Dexos licensed fluids.  

Maybe you should show your dealer the Mag Moss Warranty Act and try to demand free transmission fluid?  Let me know how it goes.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
