Everything runs and drives great, a ton of work into the truck, lots of new parts, seals from the bellhousing back, new motor mounts, tranny mounts, oil pan, starter, all brake lines, interior is clean, no rips or tears, leather power, loaded, 6disk, Bose. No check engine Lights, broken gauges, or anything like that, everything works like it was factory. Drives and runs nice and smooth. The drivetrain came from a 2003 Silverado 2500hd.
