The 2004 GMC Envoy was equipped with a 4.2L 6-cylinder engine as standard on all its trim levels. This engine requires fully synthetic 5W-30 motor oil and holds 7 US quarts including the filter. The oil plug is 15mm in size and needs 20 ft/lbs of torque to be removed. You should change the oil every 7,500 miles or 12 months for this vehicle. If you decide to tackle the job yourself, expect to spend between $35 and $60 on fluids. Alternatively, taking the car to an oil change shop could cost you between $120 and $150.
The GMC Envoy XL from 2004 requires SAE 5W-30 oil for its engine.
How can I diagnose if there is a faulty part causing my transmission to not shift, or if it's an issue with the transmission itself? Specifically, I want to identify the component responsible for shifting on the 4WD control dial inside the console of a 2004 GMC Envoy.
