ok i tracked down a 5.3l out of a 04 tahoe, 600$ for motor, harness, and ecm (only 32,000 miles!!!) not a bad snag, but no tranny. i will probley track down a 4l65e but does anyone know if the ls ecm has trans control? i really dont want to do a stand alone harness just for a tranny, and i figure going with the 4l65e vs 60e would probley be a good idea and cheaper since i dont even have a 60e. could go with a sm465 but the the splines are different for the transfer case (could just leave off the drive line and mob a two wheel drive lol) any help would be appreciated!! i'll post some pictures on thursday of the new ls
