stock 4l80e 1-2 shift
stock junkyard 80e, stock converter (sluuug 
), 0 TQ mgmt. The tall 1st gear is fun on the street....I've recently changed my 2-1 downshift to 40 mph, but I haven't uploaded that change yet. You'll need to turn your volume up a bit, my Iphone doesn't capture sound very well apparently.

Not really sure at this point....it's really down on power with all the stock 4.8 exhaust on it 
Had to put all the stock back on to pass visual inspection and never got around to getting headers back on.
But when I did have them on, my logging software was showing around 480 crank HP.

yeah it had the downshift delay on autos but its still quicker than a manual when you cant skip gears.but most transmissions dont like the 4-2 or 3-1 shift its really hard on the drum and bands.
