Hello all, its Josef & Tiffiny from Baton Rouge. We have a 96 Sierra Z71 ecsb that has been in my wife's family since it was new and it's a permanent member of our family. He's a bit sluggish with 175k miles on the clock and some strange noises are coming from the tranny so, it's time to consider replacing it all at once. My father had a '00 Sierra ecsb 5.3 and it was still going strong @ over 260k miles when he sold it. My intentions are to swap in a 5.3/4l60 from a newer (non drive by wire) vehicle for obvious reasons. Other than that, we have a few Mustang GTs that aren't to be messed with
