My understanding is that a remanufactured transmission is a used case with all new guts in it. 
That is probably what I am getting for my truck. A remanufactured (vs rebuilt) is okay by me. Had one put in a Vette and no problems. 

At this point I just need my truck back. Dealership has a new transmission ready to install GM won't approve, they  would rather have me wait for months if the part is ever available and experiment on a fix. If the part doesn't fix it it, then it's a new transmission anyways..

 

I have owned 17 GM and sold thousands new and used in a 16 year career,  what a slap in the face. Worked many years selling the brand 60 70 hours a week and converted many Ford Dodge Toyota owners to Chevy. Something changed the last 10 years..

 

With all that being said, not bashing GM or Chevy, I understand things happen, just make it right.  17k mile truck under warranty in showroom mint condition, just get it fixed..

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

Add me to the list of people waiting on a transmission valve body. My 2019 Denali 6.2/10spd that I have had since new was completely fine when I parked it in the garage. The next day it had only one gear. Less than 25k miles on it in 5 years. Been sitting at the dealership for a month. Happened a few days before the 5-year warranty expired, so I'm in a loaner at the expense of GM/dealer but I sure do want mine back. It's been there for about a month now. They claim I'm one of 4 or 5 people waiting on the part and they have no idea when they will get some.

Has Ford or Dodge had problems getting truck parts?

 

Actually looked at a loaded Ford Lariat and a Dodge TRX yesterday. Having my 17k mile truck in the shop for 7 weeks now waiting on a part with no ETA is frustrating to say the least.  My wife was wanting to trade her Gmc Denali in for another one but not sure we will be going the GM route this time around which furiates me, have owned 17 GM vehicles ever since I started driving 34 years ago....

 

Hopefully this week the GM District Manager will contact my Dealership and approve the Transmission install so i can get back on the road. My Dealership has had a transmission in stock for over a month ready to install but GM has refused. If my transmission is good but the valve body is bad, why can't the dealer just send my 17k mile transmission back to Detroit and have GM install a new Valve Body then refurbish and resell??

If you are still within warranty, contact GMC customer service.  They will start a case and help to expidite the part order.  The process is after first contact, wait 2 weeks, and then theu escalate to parts division, within 48 hrs theparts division will contact you to let you know how long.  My 48 hrs was Friday, so i should get a call on Monday.

Wanted to reach out to the forum to see if any one has needed a valve body replaced for their 2023 Silverado? I'm currently in the process waiting on the part to show up at the dealer, going on for about a month now. 

 

I bought the truck new in Jan 2023, 5.3L Custom Trail Boss, and everything was fine till about 15K miles when I noticed a very hard downshift when accelerating, anywhere between 30-70mph. Usually the shifts were very violent, sometimes even turning my cruise control off because the truck chirped the tires and broke traction. Eventually took the truck to the dealer late November 2023 and they tried the software approach, which I understand, but no dice on that being the fix. I did some self-diagnosing and realized the hard shifts only started happening around 140 degrees on the transmission gauge and somewhere between 6-8 gear. Was able to get the truck back in to the dealer mid-Dec 2023 due to their availability, and was diagnosed with the valve body needing to be replaced on the transmission, and now stuck waiting for the part. 

 

Per the Service Advisor, there is already a new part number and a new manufacturer for the valve bodies, so perhaps GM is addressing a somewhat of an issue with the original valve body? Now the weird part is apparently GM is beholden to this manufacturer on when they ship out these valve bodies as parts orders, only receiving shipment once the local region has hit a certain quota, per the Service Advisor. I mean, at least GM has me in a comparable rental, but I sure would like to be back in my truck at this point. Curious if any forum member has had a similar issue in getting a new valve body for these 10-speeds on the '23 Silverado?

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      By KARNUT · Posted

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.
