Z71 2017 Automatic Gasoline mileage: 250 KM 4WD Peace be upon you and God's mercy and blessings. I am offering a 2017 GMC Sierra fully loaded Z71. The engine is in perfect condition. The transmission was opened to change the torque converter due to a manufacturing defect, and the clutches and oil pump were machined only at Mohammed Al-Dosari's workshop in Riyadh five months ago, and everything is fine with it; there are no complaints. Four-wheel drive is in perfect condition. The body is original with no repainting or bodywork. Additions: Catch can + transmission cooler 40,000 units + disabling the daytime running lights, anti-slip feature, and ABS.
