GM can and does make changes to 'what is available' and 'what comes with what' on a regular basis.
  2. That's true! (it's called 'remote mirror folding' in the personalization menu's and owners manual) Remote Mirror Folding When on, the outside mirrors will remotely fold or unfold when the Remote Keyless Entry (RKE) transmitter 'lock' or 'unlock' button is pressed and held.
  3. https://gm-techlink.com/?p=12050 New Duramax Diesel 3.0L 6-Cylinder Engine Powers Up Silverado 1500, Sierra 1500 September 13, 2019 The all-new Duramax® Diesel 3.0L inline 6-cylinder turbocharged engine (RPO LM2) delivers plenty of power — producing 282 horsepower and 450 lb.-ft. of torque — along with impressive fuel economy — an estimated 30 mpg (7.8L/100km) highway on 2WD models — in an efficient package. (Fig. 1) Available on 2020 Silverado 1500 and Sierra 1500 models, it’s paired with the 10L80 10-speed automatic transmission (RPO MQB). Fig. 1 Turbocharged Performance The dual overhead camshaft (DOHC) engine uses an aluminum block with six pressed-in iron sleeves and a high pressure diesel fuel injection system. The lower oil pan is made of dual-layer stamped aluminum. (Fig. 2) The 3.0L diesel engine uses SAE 0W-20 dexosD diesel engine oil. Do not add anything to the oil. Fig. 2 The turbocharger is a variable nozzle design with an electric vane actuator attached to the exhaust manifold. The Variable Geometry Turbine (VGT) body assembly contains a contact-less inductive VGT position sensing element that is managed by a customized integrated circuit. The VGT position sensor provides a signal voltage that changes relative to the VGT vanes angle. The customized integrated circuit translates the voltage based position information into serial data using Single Edge Nibble Transmission (SENT) protocol. The VGT position sensor information is transmitted between the VGT body and the Engine Control Module (ECM) on the signal/serial data circuit. The ECM decodes the serial data signal and is used as voltages for the VGT position sensor. The intake manifold houses the integrated intercooler. The intercooler system includes an air cooler/heat exchanger built into the intake, a charge air cooler (CAC) radiator assembled in the front fascia, and an electric coolant pump. The CAC coolant pump provides operational and diagnostic feedback to the ECM. (Fig. 3) Fig. 3 The fuel system features a 3-phase electric fuel pump in the fuel tank that is controlled by the fuel pump driver control module and the ECM. Fuel is pumped from the fuel tank to the fuel filter assembly, which consists of a fuel filter/water separator, fuel heater, fuel temperature sensor, and a water in fuel sensor. The ECM controls the fuel injection timing and has the ability to learn injector timing performance. Under the correct operating conditions, the ECM will pulse each injector individually and measure the changes in rotational speed of the crankshaft using the input from the crankshaft position sensor. The ECM will run this diagnostic at one fuel rail pressure operating point for each injector. The ECM stores the injector timing value. Active Thermal Management The Active Thermal Management (ATM) system on the 3.0L diesel engine distributes coolant through the engine in a targeted manner, sending heat where it’s needed to warm up the engine and reduce friction. It also promotes quicker heating of the passenger compartment and enhanced engine cooling during high power operation. The system uses a conventional engine-driven coolant pump while the ECM controls the ATM system using feedback from various coolant temperature sensors. The engine coolant flow control valve assembly that is part of the ATM system uses two chambers to control coolant flow. (Fig. 4) The first chamber controls the coolant flow rate across the radiator and bypass. The second chamber controls the flow to the transmission and engine oil cooler as needed, providing heated coolant from the EGR/turbocharger return circuit or cold coolant directly from the pump outlet. Fig. 4 Exhaust Aftertreatment System The exhaust aftertreatment system is designed to reduce the levels of hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate matter (PM) pollutants remaining in the engine’s exhaust gases before they exit via the vehicle’s exhaust tailpipe. NOx is controlled by a Selective Catalytic Reduction (SCR) converter combined with precise injections of Diesel Exhaust Fluid (DEF), while PM is controlled by a diesel particulate filter (DPF). To reduce packaging volume and manufacturing cost, the SCR catalyst on the DPF is coated to form an SCR-coated DPF, or a Selective Catalytic Reduction on Filter (SCRoF). The close coupled DOC along with the SCR on Filter are integrated into one assembly. In the DPF, particulate matter consisting of extremely small particles of carbon remaining after combustion are removed from the exhaust gas by the large surface area of the DPF. DEF is injected into the exhaust gases prior to entering the SCRoF stage. Within the SCRoF, NOx is converted to nitrogen (N2), carbon dioxide (CO2), and water vapor (H20) through a catalytic reduction fueled by the injected DEF. The exhaust aftertreatment system components (Fig. 5) include: Exhaust temperature sensor DEF injector mounting flange Exhaust pressure differential sensor pipe Exhaust pressure differential sensor pipe EGR flange NOx catalytic converter assembly Particulate matter boss Exhaust back pressure valve Fig. 5 The DEF fill, identified by a blue cap, is located behind the fuel fill door. (Fig. 6) After filling the DEF tank, unless the DEF tank was empty, there may be a short delay before the increased fluid level is detected and the DEF level indicated on the Driver Information Center is updated. Fig. 6 Automatic Engine Stop/Start System Designed to help conserve fuel, the Automatic Engine Stop/Start system may turn off the engine when the brakes are applied and the vehicle is at a complete stop, if the required operating conditions are met. The tachometer will read Auto Stop. The Stop/Start system can be disabled and enabled by pressing the Stop/Start switch on the center of the instrument panel. (Fig. 07) The system is enabled each time the vehicle is started. Fig. 7 An auxiliary electric engine coolant pump motor (Fig. continually circulates engine coolant through the heater core while the Stop/Start system has shut down the engine and the ambient temperature is colder than 59°F (15°C) to maintain the passenger compartment temperature. Fig. 8 The 3.0L diesel engine also features an active engine mount system to enable an optimal balance between vehicle Noise Vibration and Harshness (NVH) performance and vehicle dynamics, including during Automatic Engine Stop/Start events. There is a single solenoid on each active engine mount that is energized during an ignition event and switched on for idle and driving events. The solenoid valves are supplied with battery voltage through a single fuse and are controlled by the ECM. Normal Sounds After Engine Shut-Off After the 3.0L diesel engine has been shut off, several sounds may be heard in the engine bay. These sounds may be caused by the following components performing a cleaning cycle: Turbocharger linkage (Fig. 9) Exhaust throttle valve Intake manifold swirl valve Fig. 9 The sounds are normal operating characteristics of the vehicle and do not impact the designed performance or reliability of the vehicle. Refer to Bulletin 19-NA-188 for additional information.

  4. Hold the lock button on the fob a little longer and they will fold. "If equipped, press and hold 'lock' on the RKE transmitter for approximately one second to remotely fold the exterior mirrors"
  5. Some must think GM is doing something correctly.... https://www.tfltruck.com/2019/10/gm-full-size-trucks-outsell-ford-f-series-q3-2019-sales-report/
  6. AND, in the 2020 sierra owners manual: 2500 Series and 3500 Series Standard Box (Except Double Cab Diesel) 136.3 L 36.0 gal and 2500 Series and 3500 Series Long Box (Except Regular Cab Diesel) 136.3 L 28.0 gal To save everyone getting out the calculator 136.3 L is same as 36.0 us gal (not 28 gal) Regardless, assuming they are both 136L and the 28.0 is a actually a typo, that still leaves leaves double cab std box with 111 L /29.4 gal and the reg cab long box, with a 106 L / 28 gal.
  7. They aren't included. Optional on all trims: PTT Trailer Tire Pressure Monitor Sensors, includes set of 4 sensors. Sensor functionality requires (U1D) In-vehicle Trailering App to be ordered with the vehicle and installed by the factory. Sensors will be shipped loose with the truck and will need to be installed on trailer by customer. System is capable of monitoring up to 6 wheels. Additional or replacement sensors are available through GM Accessories These 3 are standard on 1500 SLT, AT4 and Denali ProGrade Trailering System, includes (PZ8) Hitch Guidance with Hitch View and (U1D) In-vehicle Trailering App Hitch Guidance with Hitch View with image adjustment, Pan/Zoom/Tilt - Included and only available with (ZL6) ProGrade Trailering System. In-vehicle Trailering App, System, includes checklist, trailer maintenance reminders, trailer security alerts, trailer mileage, tow/haul reminder and trailer electrical diagnostics - Included and only available with (ZL6) ProGrade Trailering System.
  8. Interesting. Because of this thread, I verified today that brake pedal is unnecessary on '18 L5P (even though I usually use it anyway). Had both a 15 and a 16 1500 around here. They both required the pedal be pushed -- the shift lock did work on them. also works on GM car that is here. The other difference is that this L5P can be started without putting foot on brake pedal --- again, a difference from the 1500's which wouldn't start without pedal pushed. Could be it's in need of repair.
  9. Might be true on 2020's, if the 'gauge' is accurate -- I don't have a '20, but it sounds like there are issues with it. 2011 there was no def gauge at all -- just the miles remaining warnings. 2012 - 2019 have a def level indicator. Won't tell you if it's full -- only gives a % indication if it thinks their is less than 30%. Above 30 it just says 'OK'. Which of course is useless for 'checking to see if full'. Ya, I know, it's a 2020 thread.
  10. Interesting. Perhaps a new feature with the 10 speed? My 18 L5P doesn't require foot on the brake. '11 LML didn't either.
  11. 'Remote start disabled' if there is an active CEL was a 'feature' on earlier generations as well. Dealer not filling the def tank at delivery has also been an ongoing problem, for as long as we've had def. For many, this means and early and unexpected warning to add def -- and an assumption that it was because of high consumption rate. Just like fuel tank level, the def tank is NOT filled at the factory. For trucks purchased after sitting on a lot this is probably a good thing.
  12. 2018 TG5 Single-slot CD/MP3 player 1 - On Crew Cab model replaced by (U42) rear seat DVD/Blu-Ray Entertainment Package when (U42) Entertainment Package is ordered. Was available in 2019 1500's on the 'limited' models (the old body style ones) Also on 2019 HD's Doesn't seem to appear in order guide for 2019 'all new' 1500's and also not in any 2020's.
  13. I still think they need to return to making factory cassette player available.... My collection is sittin' there waiting....
