My 97 ext cab 4x4 has the 5.7 and 4l60e, both are junk/on their way out. Trans lost 3rd and motor drops oil pressure when warm and starts knocking. I know someone parting a 02 Sierra Denali with the 6.0, and seems like a good price for the engine, trans, harness and computer. Might even swap out for the leather seats at a good price.
Anyway truck is in the snow right now, does anyone know what trans was in the denali's? Besides the big 4 items, is there anything else i should grab while the truck is around? Still reading up on the swap, but looks like a option then finding another 5.7/4l60e combo. Thanks
