2004 Chevy 1500 Silverado 4x4 Pickup

This truck runs great, doesn’t use any oil, and has a lot of new parts. The transmission went out so I had it rebuilt by Angles Transmission in Merriam and it has less than 200 miles. They also replaced a U-joint on the front driveshaft that was bad. It has brand new 10 ply Goodyear Kevlar tires. New shocks. New front, rear, and emergency brake pads. The normal rust for this model truck (in the cab corners) was repaired by Linden Auto in Merriam. They also installed a new headliner and driver seat. The engine light comes on and goes off and has done that since I purchased it and the previous owner had same problem. Not sure what it is but probably some sort of oxygen sensor. It does have a few war wounds but nothing major. It is mechanically sound and everything works. Options include electric windows, door locks, tow package and tilt wheel. AC and heater work great.
