GMC Sierra SLE 2014 Automatic Gasoline mileage: 1 KM Peace, mercy, and blessings of God be upon you. I am offering my GMC Sierra 2014 car. The car is clean, original engine and body. Everything in the car works perfectly. 4x4. Mileage: 340,000 km. (Only the transmission torque converter was changed, and this is a manufacturing defect in the Sierra). I have added modifications worth a significant amount, most importantly: - ECU remapping to disable the 4-cylinder system for the safety of lifters and the engine. - Transmission cooler. - ABS disabler. - "Sari" light disabler (likely referring to a specific warning light). - Truck bed cover. Original parts (Jamihiyat - likely referring to original dealership parts or specific brand parts).
