My understanding on the HD trucks is that its not all that different between the diesel and gas. https://www.gm-trucks.com/forums/topic/263193-perhaps-i-have-missed-this-in-prior-conversations-concerning-the-10-speed-behind-the-gasser/

 

Check @newdude post in that thread. 

 

 

True, but, gas trucks from 2020-2023 still were using the 6L90 so for 2020-2023 the gas use a different transmission.  So far the problem years on these 10 speed valve bodies is mostly 2020-2022 but, some are showing up in 2023 now.

Man, this thread really took off. Sorry to hear about everyone having similar issues as I did. I’m about 5000 miles into my new transmission and it’s still running fine *knocks on wood*. Keep pressuri

Quick update - Got GM customer care involved yesterday and advised them when this hits 30 days on 11-30 I will be looking to make a lemon law claim. They called me back today and advised me the valve

As the OG on this thread, first I’d like to start by saying I’m sorry for the people STILL getting dinged with this valve body issue. As far as for me, about 20K miles since the replacement and things

Do you know what the P/N's are for the old and new valve bodies, ND?

 

As I mentioned above, my dealer diag'd the problem as the valve body, and I believe I've read that there is a revised VB, which carries a different P/N than the original VB.

 

If true, I'd really like to ensure the new/revised VB is installed.

 

Thanks much,

Dan

Day 51 and my valve bodies finally showed up at the dealer today. Hopefully the end is near for me. I did a whole lot of complaining to GM customer service and made several escalations. I have no idea if that helped move things along or not.

51 days...oh boy, that doesn't bode well for me or others that are waiting on the same thing.

 

I've been in constant contact with GMCS as well, no idea if that effort will move the needle.

 

When you get yours back, Stan, please share the VB part number from the work order.

We complained to GMCS as well and have been getting constant "so sorry" emails with no ETA on a replacement valve body.  58 days since transmission failed.  I've done the NHTSA reporting, have threatened to go the "lemon law" route and GM offered me some GM rewards points for our inconvenience..  corporate greed has definitely gotten in the way of customer service.

Second time we have had to have our 2020 towed with transmission issues. Silverado 1500. First time with under 7,000 miles, transmission module was replaced, it took a month for the dealer to get the part. This time, with 45,000 miles, the transmission valve body has to be replaced. Hearing horror stories that the part is on backorder, and no clue when it will be there. Anybody have any ideas about back ordered valve bodies.  Hoping they don't have our truck for months, and they put in the new redesigned part.

Which transmission does your 1500 have, Sandy, the 10 speed?

 

If the 10 speed, you know about as much as the rest of us do, it appears GM has not provided anyone (consumers or their own franchise dealers) with an ET of when these valve bodies might be available.

 

Given that GM continues to manufacture 1000's of new vehicles, every day, with the 10 speed transmission, and all those new builds of course require a valve body, it certainly appears to us owners that GM is prioritizing new vehicle sales for dealer stock and customer orders over providing replacement parts for current owners. While perhaps not surprising, since GM makes no money on replacement parts covered under warranty, it is incredibly frustrating for existing owners.

Maybe someone in this forum is or knows an attorney…this is awful business practice. Maybe a class action lawsuit would help?

I think that is overdue.

Fingers crossed for ya, Stan.

 

Has been 21 days since mine was diagnosed as needing a VB. While not nearly as long, yet, as you and others have been waiting it's still way too long.

I really hope this fixes your problem. Please keep us updated if the new valvebody solved the problem.

Steve, I had my 2023 for less than 24 hours before the failure. I feel your pain. Did you open a case with GM? Send an email to [email protected], include your VIN, name and location of the dealer the truck is at, and request a case be opened.

 

DD, what recall notice are you referring to? From what I've read there doesn't appear to be an active recall for the 10 speeds.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Ancillary parts to the lower intake and connections went together without issue.   There was a brief pause when I leak-tested the fuel lines and injection system. Fuel was spraying all over. Lovely. O-rings weren't sealing the fuel lines to the spider, and inbound line was leaking at schrader valve, leaks at both flange nuts. It's moments like those when you just want to set fire to the whole shop, and be done with it. I was mostly enjoying the project up until that point, and was tracking to an agenda of having a running Blazer and a cold beverage in hand by dinnertime.    I found some larger Viton o-rings for my spider and some grease to get them to seat. One leak solved. Swapped fuel line Schrader core for old core. Still leaked. Swapped entire valve for old valve. Leak solved. Nudged the flange nuts a little tighter on the connections. Another leak solved. I could cycle the key / prime the pump and the intake was staying dry.    Reassembled the upper intake, with 10,000 vacuum lines, and filled the cooling system with water* (this is temporary, I'm not done with the cooling system yet).   Showtime!!   Cranked it over and smoke billowed, it was running rough. CEL illuminated and began flashing. P0300 and I somehow tripped a code for the TPS sensor, voltage low.    There's nothing as unrewarding as a vehicle that won't run (and produces the same code/problem) after hours of research and work.   Clearly I was in over my head. Was the timing off, did I stab the distributor incorrectly? Is the new distributor bad? With my limited OBD 1.5 data stream I really don't have a lot of parameters to see. The engine was pulling mad timing again (flooding?).   Think, Atlas, think.   1-6-5-4-3-2. One, six, five.....four, three, ....two. Wait a second. That makes no sense. 1 is the forward cylinder on the driver's side, so 2 should be the forward cylinder on the passenger side, not 6.    I can't believe it, but I'm looking right at it. Swapped 2 and 6 on the distributor and turned the key over, and...   It fired, coughed and stumbled, smoked, and then settled into a smooth idle. The scanner showed no codes, no lights on the dash, and the throttle was nice and responsive to gentle revs while it warmed up.   It's working!!! IT'S WORKING!!!   I paused for a late dinner, no cold beverage yet. I was determined to do my shakedown run. Did a basic safety and fluids check one more time and then went out and put almost 70 miles on it last night. She's a runner, runs good.   Came home and did a post-trip, post-mortem. The underside is dry *except* for where the last owner RTV'd the snow out of the intersection of the timing cover and oil pan. He said he had replaced the timing cover seal, but, my dude had clearly done it incorrectly and then tried to hold back fate with black RTV. Never works.   Yesterday morning I replaced the broken driver's door mirror. As much as I hate cheap Chinese parts, thank goodness for cheap Chinese parts. I think an entire new power mirror assembly cost me like $30, and it works perfectly. Replacement tail lights (faded, and one was busted) ran me about $12/side. I have a door pin kit ready to go in because the driver's door sags just a little and I want to fix that because there's nothing sadder than a saggy door.   I don't know what's next for this rig. Half of me wants to take some nice photos (there's a park nearby with a HUGE American Flag that always seems to be catching wind) and throw it up on CL/Marketplace for a couple grand and see if it flies. The other half of me... I've got a sweet running S10 Blazer that's been keeping my mind off of whatever I'm going through right now, and it's bringing some joy, and is cheaper than therapy. Maybe I'll keep it around for a little while. However, this is my 5th vehicle, just for me. 4 is really my limit, but they are not junk, so need very little attention. I don't know...there's a point where it's just too much and I don't see owning this truck long term. But I solved its major problem, got it running, so I'm going to stick a feather in my cap for now.   Sometimes we just need to get our hands dirty and fix something in the physical world to gain some satisfaction.

      Fluid Change Questions

      By Core-Lokt · Posted

      I bought the truck new in December 2022, and it's got 60,000 miles. The front cover magnet had slightly more glitter, but overall very clean, no off odor, and good-colored; really nothing to report. My truck has Hi-Lo transfer case, and the fluid looked great, as well. I have towed..maybe 1,000 miles. Yes, this was the first change for all three driveline items. I'll probably do the transmission at next oil change.
