Tru-Cool 40k on a Gen 5

A few months ago, I had a failed lifter with bent pushrod, ended up doing a large upgrade with AFM delete, stage 2 cam, and upgraded Circle D torque converter. Then I had it tuned.

 

The higher stall speed of the new TC was increasing my transmission temps during prolonged hill climbs, such as heading up the ski hill.

 

I decided to add a Tru-Cool 40k which I ordered the genuine part from Oregon Performance. 

 

I already have a Derale remote transmission filter, so I bought a sandwich adapter from Derale and put the two together, with new 3/8 hose running to & from the Tru-Cool cooler.

 

I mounted it in front of the radiator as most do, and used the provided metal straps to bend and design my own make-shift clamps. Just took a lot of dicking around with some plyers to get something that would hold it in place. 

 

The 3/8 hose runs straight down through 2 small gaps in the plastic trim and connects to my remote filter setup. 

 

I'm very happy with the results, it decreased my temps approximately 70F while going up the same ski hill ( 220F before to 150F after)

I'm curious, have you ever done the transmission thermostat delete or is it still operational. That thing usually has the transmission run hotter

Yes I flipped the pill 3 years ago so the trans thermostat has been in bypass ever since. 

 

I also installed a remote transmission mount and run Wix 51269 hydraullic filters downstream of the radiator on the transmission return line.

 

Now combined with my upgraded Circle D converter and Tru-Cool 40k, I aim to have the world's 1st million mile 6L80e without failure, lol

      Ac not keeping up

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.

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

      By bluev8 · Posted

      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?
