12000 mi | TCU reprogram due to "chugging" and harsh shifting |
54000 mi US $400 |

420-horsepower 6.2L V8 8-speed shiftable automatic 4WD w/low range
24000 mi | Torque Converter Shudder. Transmission fluid and filter replaced. |
50000 mi | The Torque Converter Shudder issue that was apparently fixed two years prior, returned on the truck. The fix included another transmission fluid flush, and a newer fluid (one with less viscosity) was added back. GM has several TSB’s on this issue. The issue has again gone away for the time being, but I will update if it returns. |
355-horsepower 5.3L V8 Hybrid 8-speed shiftable automatic RWD
3000 mi | Lurching and hard shifts. Advised to drive and transmission will "learn" |
355-horsepower 5.3L V8 8-speed shiftable automatic 4WD w/low range
4526 mi | Transmission shift logic is inconsistent for the 1-2 gear shift. Sometimes very soft, sometimes very hard. |
6820 mi | Shifting into and out of 1st gear is inconsistent as per last dealer visit. Transmission tech did a TSB “slow relearn” procedure which did not resolve the issue. Condition still present and tech says there is not TSB procedure which will improve the shift quality. |
355-horsepower 5.3L V8 6-speed shiftable automatic 4WD w/low range
20000 mi | Torn boot on front axle. Dealer found problem during regular service, and repaired it under warranty. |
