I have a 2000 GMC Sierra 1500 4.3L and when starting it backfires through the intake. Not every time but its always difficult and sometimes incredibly rough to start. It still starts but i have to hold the accelerator pedal down and usually takes a few tries. Once its running, it runs perfectly fine. Confused.

  The 6L90 in the 2020+ trucks has several improvements over the 6L90 in other trucks, so the comments made about issues with previous versions may not apply. I have been totally happy with the 6L90 in my 2021 3500 HD. The L8T has plenty of torque over a wide speed range and does not need to be held in a narrow rpm range unless you are towing near the maximum weight. Even then, six gears works just fine. Personally I don’t like what i consider the excessive shifting of most ten speeds, but i have not towed with one of these trucks with a ten speed. If you are buying used I would prioritize condition, miles, maintenance records, absence of stupid unreversible modifications, and towing history as more important than ten speed versus six speed. Make sure you try the seats out before choosing a trim level. I can drive my SLT with the leather bucket seat (premium pkg) option for 8 hours and get out feeling fine. I was uncomfortable in the SLE cloth seats with fold down center seat by the end of a 20 minute test drive. My wife loves the SLT leather bucket seats, too.

- LZ0 P06DD Code - Not Thrust Bearing Related
  
  By coreydkoster · Posted 1 hour ago
  
  I bought my '26 Sierra Denali 1500 LZ0 about two weeks ago. Thursday, at 500 miles, I got the "Reduced Acceleration" message on the DIC along with the CEL on the dash. Limped it 13 miles home. I did not notice any unusual noises. I was only able to pull one code with my scanner, P06DD. Had it towed to the dealer. They are saying that the the crankshaft end play is within spec and there is no excessive metal in the oil. They will be replacing the oil control valve solenoid. Has anyone had or heard about this issue and it was not related to thrust bearing failure? I'm just wondering what to expect after the repair and what to look out for. I have attached a link to the video from the dealer repair tech. https://youtube.com/shorts/FW_QBxnNm5A
