4l80e Swap in 99-07 GM Truck Part 3: wiring, tuning, plus a test drive

Parts links added below... This is the final installment of the transmission swap in my 2000 Chevrolet Silverado I call the UglyTruck. It's not much to look at, and when I bought it, the original 4L60e was blown and needed to be rebuilt. Rather than mess around with the stock transmission, I wanted to upgrade to something that can hold a ton more power, so the 4l60 came out, and a junkyard 4l80 went in. My other two videos I show the beginning steps of the process which include removing the 4l60 and installing the 4l80 onto the 5.3 LS with a crankshaft spacer and flat flexplate which I got at the junkyard along with the transmission. I had to modify the crossmember to make it fit, and then extend the cooler lines, and today we handled the tuning, the segment swap of the transmission, and of course the ever important test drive. Everything went smoothly for the most part, except now it is a bit slower on take off, even though I put in a higher stall speed torque converter. Right now the truck has 3.42 gears in the rear 10 bolt, but I do want to change em out for 4.11, 4.30, or even 4.56 depending on what size tire I go with. Stay tuned for more progress on the UglyTruck!
