RKE Transmitter Pocket Locations on the New Silverado and Sierra https://gm-techlink.com/?p=11125 The new 2019 Silverado 1500 and Sierra 1500 offers bench seats (RPOs A52, AE7, AZ3) and bucket seats with a center console (RPO A50).

Do Not Remove or Swap Navigation SD Cards https://gm-techlink.com/?p=11170 February 15, 2019 The Navigation Data SD cards for infotainment systems with embedded navigation (RPOs IOT, IOU) (Fig. 18) that are available on 2018-2019 Regal, ATS, CTS, XTS, Terrain; and 2019 CT6, XT4, Blazer, Camaro, Colorado, Equinox, Malibu, Silverado 1500, Volt, Canyon and Sierra 1500 models should not be removed from the original vehicle or swapped between vehicles.
New Trailering App Trailer Connection and Lighting Diagnosis https://gm-techlink.com/?p=11176 February 15, 2019 The new trailering app (RPO U1D) available on the 2019 Silverado 1500 and Sierra 1500 (Fig. 8) uses the K68 Trailer Lighting Control Module (TLCM), or Trailer Interface Module, to constantly monitor for trailer connection status, trailer lighting faults, and trailer theft deterrent purposes through the lighting circuits of the trailer.
Wheel Studs with Yellow Coating The new 2019 Silverado and Sierra use wheels studs that have a yellow coating on the lower portion of the stud threads to prevent corrosion of the threads. (Fig. 14) The yellow coating is not Loctite or any type of anti-seize coating for the wheel studs. TIP: Never apply Loctite or any other product to any wheel stud threads. Never grease or lubricate the wheel nuts, studs or mounting surfaces. Wheel nuts, studs and mounting surfaces must be clean and dry. The yellow coating is designed to prevent corrosion on the portion of the thread that is not covered by the wheel nut. (Fig. 15) The coating should not be removed or supplemented with any other product. If the coating comes off the wheel stud, it is not necessary to replace the stud. Always clean the threads of the wheel studs before installing the tire and wheel assembly. If the threads of the wheel stud are damaged, replace the wheel stud. The 2019 Silverado and Sierra are the first models/model year to receive the coating on the wheel studs. The coating will be applied on additional models in future model years.

It’s important to understand proper system operation while diagnosing the infotainment system.

Retired Bob replied to Retired Bob's topic in 2014-2018 Silverado & Sierra ModsI don't know - I input 2014 Silverado 1500 and the Web site shows this " Low Beam: H11 LED Headlight Conversion Kit Fits On: 2014 chevrolet silverado 1500 Top Rated Complete LED Light Kit with Lifetime Warranty Get it in 2 business days with free shipping if ordered within: 10h, 35m, and 13s Regular Price: $209.99 Sale Price $99.99 ------------------ Still I don't know about this site - just does not seem to me to be a 'professional, English 1st language' site. I saw this link while reading about the 2019 CES electronics show in Los Vegas .
Retired Bob posted a topic in 2014-2018 Silverado & Sierra Modshttps://tinyurl.com/y9j2hoga I made the 'tiny URL' above as the original URL was fairly long. Also, I do not know anything about these LED bulbs except what I see on the Web site - just thought they looked interesting . I have not bought these (yet). " The Headlight Experts LED Kits feature top performing Phillips Lumiled Luxeon ZES LED Panels (Same LED's used in new Audi and BMW models) to ensure you are lighting the road the best you can. These LED Kits are built in the same factory that makes almost all the OEM LED lighting for car manufacturers. These are absolutely the best LED lights on the market, and no competitor can compare. These LED lights have a blinding perfect bright white light output making them look and perform better than any other light on the market. Additionally, these are 100% direct fit to your vehicle. Just plug it in and go. " EDIT: Just read this on their site " Lifetime Warranty - you are covered for the life of the product". Does that mean that 'the bulbs are covered until they quit working' ("... life of the product?)

I went to the noco site - liked what I saw and purchased the GB40 version. Walmart sells these at about 1/2 the price on the noco Web site and noco says they honor the warranty no matter where you buy their products. I will keep it in the truck - good if I run down the battery and no one is around to jump start me. Will have it if the wife or kids call and need a jump start also. Plus I will carry it in the boat when I go out (only weighs 4lbs).
For those with truck vibrations, possible refer your dealer to this article to see if a new request to GM following these instructions might be helpful: TAC Assistance with Vehicle Vibration Diagnosis Posted on December 13, 2018 https://sandyblogs.com/techlink/?p=10581
Retired Bob posted a topic in 2014-2019 Engine, Driveline, & Exhausthttps://sandyblogs.com/techlink/?p=10589 Interesting read: "The 6.6L Duramax diesel engine (RPO L5P) and Allison 6-speed transmission (RPO MW7) available in 2017-2018 Silverado, Sierra; and 2019 Silverado 2500/3500 and Sierra 2500/3500 models have several different operating characteristics when compared to the previous generation powertrain. Some customers may notice these differences if they owned an earlier 2011-2016 Silverado or Sierra diesel-equipped model. The new 6.6L Duramax diesel (Fig. 9) shares only bore and stroke dimensions with the previous diesel engine. It features a new GM-developed control system with an electrically-actuated/electronically-controlled turbocharging system and an advanced solenoid fuel system."
