Need help on Truck 5.3 Hey guys, need some help here.....I just bought a complete pull-out, 5.3, 4L60E, wiring harness, relay box and computer. The guy told me it came out of a 2005 with about 12K on the clock. Only ID stickers/tags I could really find is on the bottom of the computer. The serv # is 12576106. When I look this # up it shows to be a 2003 model. Could this be used on a 2005? Is there anything else I could identify what year model this is? Thanks for any help you can provide.
