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 recently did an engine tune-up a month and a half ago. Additions: 40,000 BTU Trucool transmission cooler. Pro Fender shocks and control arms. Sari light switch. Lights on the tires and also inside on the mirror. It has original floor mats. It has a 3-inch front lift kit. 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.
