What did you do to your NBS GMT800 Tahoe/Yukon Today?

I did it on my 02 so the wiring is probably different but I just looked up a diagram for the rear wiring harness, then I connected the Left rear positive top to left rear negative bottom, then vice versa, and then the same for the right side. It's a bit of trial and error too, so I'd test it every time you make a connection to see how it sounds.

That was my first thought, some trial and error . I need to look for a diagram for 03-06 so I don't short my entire bose system lol

Which "shift kit" specifically?

Sonnax "smartshell" or the "beastshell"

Close ratio input carrier.

torque convertor

Beast shell for sure, already insisted on that. He also said he would swap it over to a 5 planetary. Is that what the input carrier is? Looks like the carrier in a rear end to me from pics I've seen.

5 planetary is the difference between a 4l60e (4 planetary) and a 4l65e

Input carrier http://www.sonnax.com/parts/3734-2-84-ratio-input-carrier-kit

Sonnax 2.84 input carrier kit 77284-K transforms the popular 4L60 series from an OE “wide ratio” 3.06/1.63 to a “close ratio” 2.84/1.55 for game-changing acceleration on the track. This keeps performance engines in the optimal power band while allowing a longer pull in first and second gears, improving consistency and performance.

honestly... totally unnecessary in a truck lol. but why not bcuz racetruck?

So, when I picked up the Hoe from the place who did the cam, tune etc, the ac wasn't working, worked before I dropped it off. Wasn't that concerned at the time as it was still cold, I thought it just got discharged, no biggie. My buddy who did my swap put the ac machine on and we see smoke and it's hissing. There's a small hole above the trans cooler that the shop also installed, about the same size as the pushpin deal that aftermarket coolers use to hold it to the radiator. So I called the shop to explain, nicely. Long story short, the guy insinuates that I did it and I want him to pay for it. I spent almost $4,000 and I'm trying to scam him for a $100 condenser? There we're a few other issues that went on that I'm not going to get into, but that raised my blood pressure big time! I wouldn't recommend them to anyone! So needless to say I'm gonna eat it. If I go there there'll be nothing but problems, for me, I'm sure!

Unfortunate that this shop's been such a pain in the ass for you, man. If I'm ever in Jersey I'll steer clear of them

I just gave them an honest review on Facebook. Remember, I said HONEST review.

Just a few days late but Saturday I replaced my passenger side wheel bearing after realizing it was the front diff making all the grinding. I had posted already about doing the 4x4 delete. Well Monday on my way to work the driver side bearing completely exploded at about 75mph taking me for a 3 wheel brake less ride towards the ditch and my wheel, caliper, and rotor went towards oncoming traffic. Luckily it didn't hit anything and I'm good also. If the 4x4 were still in the truck I wouldn't have lost the wheel with the cv axle as a fail safe but it made me think. On the 2wd trucks there is no fail safe. Do not neglect your bearings. Now I'm going to be checking them all periodically. The driver side gave me no warnings as far as sounds or shaking so don't just wait for that to know it's broken.

Picked it up from getting some paint work done. Clearcoat was peeling on the bumper cap, flares, and mirrors. Also got the hood re-painted!

Came out awesome! I'm guessing they had to respray where the clear was peeling.

^^Yes. Sanded, painted and clear coated. Looks so much better. The peeling was driving me crazy. Truck would be clean and look good until you got close to it and saw the peeling.
