Anyone had their transmission replaced under GM Program# 2044120? Talked to dealer about this today and GM is not replacing parts but the whole transmission. I set up an appointment and asked if mine really needed it as it seems to not have any issues. Of course they said I should and would take a couple of days. Suppose to drop off Monday morning.

did you receive a recall notice or take the truck in for service under warranty?

This is nothing new, been policy since the 8-sp was introduced. Dealers are not to open them up for repairs.

I have a 2015 denali w. the 8 speed and it has already had a new torque converter. Now i still have the delayed engagement upon start up. They issued this #16-NA-014, which states they will install a new stator shaft?? This is the issue I have now. I wasn't' crazy about them opening my trans. Are you sure and saying they will not open it up just replace it???? Is there a TSB or something written.

 

Thanks

They sure do... just had the stator tsb done and they took it all apart and put it back together again. I even have the work order to prove it lol.

The transmission is currently on exchange through the GM Product Quality Center (PQC). No transmission repairs, internal or external, are allowed at this time. If diagnosis has determined the need for any repair to the transmission, contact the PQC to discuss the information/diagnostics that led to the need to repair the transmission assembly before performing any repairs.

That's nice... also totally out of date and completely irrelevant.... research the stator tsb... yes dealers dismantle the transmission.. end of story.

I have to wonder with all the searching, jerking, hesitating and jerking again what the hell its doing to my drivetrain life cycle.

Nothing in the mail. Checked for recall with my Chevrolet app and popped up. GM program #2044120 date issued Jun 21,2016.

Program title: Cracked 2-3-4-6-8 Clutch Piston

 

Program description: Certain 2016 model year Cadillac CT6, Chevrolet Silverado LD and GMC Sierra LD vehicles, equipped with an 8-speed automatic transmission, may have a condition in which the 2-3-4-6-8 Clutch Piston is out of specification. Parts exhibited a crack condition as cast after machining. As a result the vehicle could exhibit 1-2 up shift slipping ot a flaring condition.

 

Safety Risk Description: The Vehicle could exhibit 1-2 up shift slipping or a flaring condition.

 

Repair Description: Replace the transmission.

 

This is all I have information wise. Dealer confirmed I would get a entirely brand new transmission. I'll keep you all posted.

Is there anyway we can confirm that we are eligible for this recall of the transmission?

I still have the delayed engagement when I start my vehicle and put from park to drive.

    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
