  1. I always go 4x4 even if it’s rarely used. Better to have it and not need it instead of needing it and not having it. Resale value is higher as well and the 1mpg difference (if that) is Negligible.
  2. Get GM corporate involved since your dealer is not competent. https://www.gm.com/lemon-law.html Contact Us Via Email [email protected] Contact Us Via Phone 1-866-636-2273 Monday to Saturday 8 a.m. to 9 p.m. EST
  3. Here is a link to my YouTube channel. Recently did some videos on all 3 during this lockdown. https://www.youtube.com/channel/UCRxevu2UVj-pRTpqY334XxA/videos https://www.youtube.com/channel/UCRxevu2UVj-pRTpqY334XxA?view_as=subscriber
  4. #16-NA-175: Shake and/or Shudder During Light Throttle Acceleration Between 25 and 80 MPH (40 and 128 KM/H) at a Steady State - (Oct 11, 2018) Some customers may comment on any of the following conditions: A shake and/or shudder during light throttle acceleration between 25 and 80 mph (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. A shudder feeling that may be described as driving over rumble strips or rough pavement. Shudder feeling is evident in both Drive and M7 MY15-16 & L7 MY17, MY18 and MY19 mode. Important: Do NOT replace the torque converter or transmission assembly for this condition. Engineer reviews have proven that replacing the torque converter does not provide a long-term solution to TCC shudder. A revised service procedure will be released in Q1 of 2019. If the vehicle experiences a repeat shudder condition, this document should be followed again. All part replacement claims will be subject to engineering analysis. Any part(s) determined not to be defective will be subject to a possible claim debit. Note: This procedure has been updated to eliminate the replacement of the transmission oil filter. To confirm TCC Shudder, the vibration concern must be created in normal operation (Mode A) of the test. If the concern is gone with the torque converter clutch disabled (Mode B, TCC Open) and is gone with torque converter clutch enabled (Mode C, TCC Locked), then the vibration root cause is TCC Shudder, and the fluid flush procedure corrective action described below should be performed. If the concern is not present in Mode A, then the vibration concern is NOT TCC shudder. If the concern is still present with the torque converter clutch disabled (Mode B) or with the torque converter clutch enabled (Mode C, TCC slip speed at zero), then the vibration root cause is NOT TCC Shudder. Vibrations not identified as TCC Shudder should be further investigated using the Vehicle Vibration Diagnosis in SI as a starting point. Service Procedure Important: Requires Mobil 1 Synthetic LV ATF DEXRON HP transmission fluid. Note: Replacement of the transmission oil filter is not required for this procedure. Drain, Clean pan/magnet, Oil Fill, & Remove fluid from the oil cooler lines. Note: If you find that the fluid is cloudy, milky, or appears to be contaminated with water or engine coolant, DO NOT proceed with below steps. Follow Both SI Procedures for Cooling System Leak Testing and Engine Coolant/Water in Transmission. A.) Use filtered compressed air regulated to 60 psi to remove transmission fluid from the transmission oil cooler lines. B.) Remove the transmission fluid pan and drain transmission fluid following SI procedures for the application you’re working on. Discard all oil. C.) Clean the pan/magnet if any metallic particles present. Install the transmission fluid pan and refill with new Mobil 1 Synthetic LV ATF DEXRON HP transmission fluid following the Fluid Fill Procedure in SI to obtain correct fluid level. The shudder should be improved after the completion of this flush procedure. Note: Shudder should improve directionally right away, but for full affect, the vehicle may need to be driven up to 200 miles (322 km) and a minimum of two cold to hot drive cycles before determining if the fluid flush corrected the condition or not. Do not re-evaluate vehicle for additional customer shudder concerns until the vehicle has been driven 200 miles (322 km).
  5. Has your 8l90 transmission had the new fluid installed? If not I would get it flushed. You should be able to get it done free with some convincing if your truck has shudder problems or RPM fluctuations when highway cruising. http://gmauthority.com/blog/2019/08/tsb-seems-to-fix-8-speed-automatic-gm-transmission-problems/ https://gm-techlink.com/?p=11127

  7. I have AFE Momentum GT. I may end up selling it. It looks nice under the hood but I can’t tell that it makes a difference aside from hearing a lot more intake noise. I’ve swapped back and forth and truck feels the same besides hearing more engine growl and noise with the AFE. This was one of the top rated in blackbear tests but without a tune don’t expect a seat of the pants difference.
  8. AFE sprint booster works well on my 2018 and it’s made in USA ?? instead of pedal commander which is from turkey ??
  9. Go to a different dealer. Example: We had oil pressure gauge on lml suddenly read 120 psi anytime above idle. GMC dealer said there was no max spec for oil pressure just minimum. I suggested they change sending unit as everything was fine the first few years. They politely offered me an oil change I’d have to pay for I complained to GM customer care and setup an appointment with Chevy dealer across town. They replaced sending unit and all was back to normal. Original dealer must have gotten a call from GM because they called me and offered a free oil change as an apology.
  10. Hopefully it’s good to you after this. You want any and all failures to happen during warranty period ? Of course no failures are the best option.
  11. My 2 year owned review of Extang Solid Fold 2.0
  12. Make sure you get the service history for any truck you buy. 2017 was the first year for the l5P Duramax. 2011 - 2016 LML Duramax. The only difference between the 2500 and 3500 SRW was the rear leaf spring pack, everything else (rear axle, frame, truck) the same. Of course higher payload sticker on the 3500 due to the extra spring pack.
  13. Looks like you are missing the lower door seal?
  14. Have you tried cleaning or swapping in another Mass Air Flow sensor? Does it still misfire if you disconnect MAF?
  15. Paint seems OK on plastic. The rubber seal is the older design. I opted to keep my factory seal + antenna and just swapped covers.
  16. I have bilstein 5100 on 3rd setting for 1.5 - 1.85” lift. I got 1.85” on 3rd setting. Rides fine. Stiffer than stock yes, but not a bad ride. If you go to 4th setting for 2” - 2.25” lift people have reported it rides really stiff. You are compressing the coil spring to achieve lift so the more you compress the stiffer ride is.
  17. Mine has been over full since day 1. 2 years later it hasn’t moved.

  19. What air pressure you running? Sent from my iPhone using Tapatalk
  20. It is mounted on the font because it is the lowest point on the roof. If mounted in the middle or back, it would be the highest point and interfere with low parking garages, low garages, etc.
  21. I’m wondering the same thing. Either will be too soon and cases spike again or everything is ok and continues on the downtrend. What happens this coming fall? Another lockdown? No worries as It has run its course for the majority?
  22. I had a hard time finding a 6.2 crew standard bed max tow SLT K2xx in 2018 (now previous gen.) Love the max tow and the upgrades it comes with. Would take it over z71 or AT4 any day. I like AT4 styling but you can make any trim off road looking with lift, tires, etc. Ended up flying to Laura Buick GMC and it was worth the trip to get what I wanted and best deal I could find. 16k off 60k msrp. Had to do GM financing to get all the discounts.
