  1. Will the harnesses be the same for the same style seats from a 2019-2022 old style to a 2022 refresh? Example. My driver's seat is cloth, powered and heated. My passenger seat is cloth, manual and heated. If I get the same setup in leather, is the harness the same?
  2. Does anyone have pictures of a white truck with white wheels? I think these RST wheels with a white background on a white truck would look nice.
  3. GM tried that.
  4. Not with the current gas prices. Although I don't expect the prices to stay this low forever, the price of gas will continue drop as the demand for oil diminishes. I drive a Cadillac ELR which is a plug in Hybrid. Essentially it has a 40 mile all electric range and then switches to a typical gas hybrid. When the price of a gallon of gas drops below $2.50g, it's cheaper to run the car as a hybrid than to charge it using electricity at 13c per kWh. GM should revisit the Via Motors experiment.
  5. So I wanted to give an end of the year update to this thread. I went all summer without any issues while towing this summer. We had several short (<50 miles) tows and several longer (65, 90, 100) mile tows. The V6 gets a workout but has been getting the job done. I always fill up with E85 before a tow to maximum power and cooling. But I ran into trouble this weekend with the last tow of the year. 80 mile trip one way, 70mph, 15-20mph sustained winds. On the trip home, I would hear an audible noise from my transmission on almost every downshift. The sounds was more clunky and less grindy. Trans fluid temps ranged between 190 and 198. The frequency of the noise has me concerned. From some of the other research I have done, it sounds like the noise might be coming from the torque converter. I'm not sure what to do next. I love the truck but I'm not sure if I'm asking too much of it. Fully loaded for my use, I know I'm under the towing capacity of 7100# and GCWR of 12800# but not by much. At the lightest I tow I'm probably 1,000# under each but at the heaviest I'm probably only 300-500# under those ratings. The other thing I'm not real thrilled about is the passenger rated tires that came on the truck. They are great for fuel economy but the side walls are way too soft. I've already broke the seal on the bead on two of the tires doing light off roading. With the additional cooling mods I should do and the purchase of new tires, I'm considering replacing the truck.
  6. ? Not really. The Engine Oil temps return to normal under a normal load. The screen shot I posted is near the end of a long incline. I also purchased the 190* thermostat that I plan on testing.
  7. I wanted to share my recent results and thank Jon for taking the time to document his testing for the community. I own a 2018 Silverado Custom V6 4x4 I use to tow a 4,500# (fully loaded) travel trailer. Factory cooling setup, no external engine or transmission cooler. I've made more than a dozen trips without any issues. However, twice I've experienced shuttering and hesitation from the transmission. The last time it happened I checked my transmission fluid temps on the display and it read 228*. I watched it closely for the remainder of the tow and the temperature never dropped below 220. Even when the truck was parked and the engine running, the temps wouldn't drop on their own. At the time, I didn't have a way to check my engine coolant temps or engine oil temps. I believe the engine coolant temp gauge reading 235* but as I now know that is a dummy gauge which doesn't really mean anything. Which brought to this thread. I have HPTs because I used to do a lot of tuning back in the day. I pulled the tune and made only the changes to the fan settings as described in this first post. I did some logging under normal conditions (not towing) and noticed that the transmission temps would get up to 190* after 20 minutes of driving. If the Engine coolant temps would creep up to 200* I would see the desired fan speed increase and the ECTs drop back to 194-196. Engine oil temps stayed pretty consistent ~215*. Ambient air temps were in the mid 50s. I also logged my next tow. Under normal towing load the transmissions temp were about 195*. Just like before, as the Engine coolant temps would creep the desired fan speed would increase and bring everything back in line. Max Engine coolant temp was 221*. It was the Engine oil temps which surprised me. While towing, the engine oil temps would stay around 230*. But on long uphill grades, I saw the temperatures get up to 261*. Ambient air temps were in the mid 50s as well. New Fan Settings (Normal Driving) 55* Ambient Air Temps: Engine Coolant Temperatures: 194*-201* Transmission Fluid Temperatures: 180*-190* Engine Oil Temperatures: ~215* New Fan Settings (Towing) 55* Ambient Air Temps: Engine Coolant Temperatures: 200*-221* Transmission Fluid Temperatures: 195*-198* Engine Oil Temperatures: 230*-261* Unfortunately, I wasn't able to log the truck while towing with the original fan settings. I can only confirm that my max Transmission Oil Temperatures was 228* and they wouldn't drop below 220* even after idling for 15 minutes. I would suspect I would see very similar results to Jon's original post where the Engine Coolant Temps got to almost 230* and the Transmission Fluid Temps rising into the 230s with no hope of return. Summary: Under the given conditions, the new fan settings recommended by Jon work. Anytime the Engine coolant temps started to rise the desired fan speed would increase and put all temps back into check. I will do more logging when ambient air temps increase. I would expect all the temperatures would increase slightly. But I'm confident the new fan settings will be able to keep things in check under normal load, keep things from getting out of control under hard pulls, and return things back to normal quickly after a hard pull. Below is a snapshot of the log while towing at the end of a long up hill grade. Thank you Jon for sharing this information with the community! I believe this should be the first cooling mod for anyone with an K2XX.
