I have a 2007 chevrolet Tahoe. Transmission is done. Motor has 350,000 miles on it. I have a rusted out 2006 chevrolet silverado with 5.3 4l60e Transmission. Will the power train interchange. The body is falling apart on truck. Body on Tahoe is solid. Just need to know if it will interchange and what I might need to do when I swap.
