Z71 2016 Automatic Gasoline mileage: 220 KM 4WD Peace, mercy, and blessings of God be upon you. I present to you a Sierra 2016. Original engines, checked from the engine to the gearbox and differential. The gearbox was removed only for the torque converter, a common defect in GMCs. The seats are still in their original plastic covers. I just did an engine tune-up a month and a half ago. Additions: 40,000 BTU Trucool transmission cooler. Pro-Link shocks and control arms. Sari light switch. Lights on the tires and also inside on the mirror. It comes with a 3-inch lift kit. It has original floor mats. And it has a tune by Al-Saqri, very safe, of course, without a dyno. Note: The torque converter was changed at 190,000 km, which is a common defect in GMCs at this mileage.
