What did you do to your NNBS GMT900 Tahoe/Yukon Today?

use all caps when entering the vin, this one is accurate, I have used while vehicle hunting online because dealers either post incorrect info, don't know what they have, or flat out lie.

FWIW, this was one of the VIN decoder websites that was generating incorrect info for my VIN vs. what's listed on my build-sheet..... mostly to do with the upgraded cooling/trailering package and shorter rear diff. ratio.

where did you get the build sheet from?

Not trying to be a smarta$$, but did your tranny guy explain how putting the vehicle in 4WD reduce the load on the transmission? The transmission is still transferring the same torque to the input shaft of the transfer case whether the transfer case is driving just the rear or the front and rear axles.

NOPE!

Hence my use of the word 'supposedly.' I was hoping that someone would either support or debunk it, if only for my own curiosity.

Maybe while in 4LO but not in 4HI.

Good thing that didn’t last a few more seconds. My ears!

i ran my vin on that one just now.
It's super generic info, much of it is wrong or just not specific.
Some is right, like the LT package.

But it did have the correct rear end ratio.

Inside of my glovebox.

Well, changed the leaking water pump, thermostat, and cracked radiator.
All aluminum radiator from Alloyworks 3 row for $300. It’s 1-3/4” thick versus stock 1” on my LTZ with K5L cooling. Stock rad seemed very slim for “heavy duty cooling”. When I had to use the Tahoe to tow my 7500 lb travel trailer in the mountains it hit 3/4 on the coolant temp which I imagine is over 240?? Hopefully this will be better.

Hauled family to and from restaurant for our birthdays. Watched all the lunatics speed past and either crash into each other, into the water or get pulled over by the cops. Busy night for police and fire on the highway, never seen so many fire engines on the highway (I-95) at one time on such a short stretch of road. Crazy.

Even crazier, my sister is considering a Chevy to replace her Kia! Someone call the Guiness Book of World Records!

I think you'll really like the bigger radiator. My temps when pulling have held around 190 with my 3" radiator.

Checked for a leak in the air-lifts. Thought perhaps I'd stretched them a little too much while jacking things up to attach the bars on the WDH during the western trek but after finding one of the nipples at the top of the bags loose - and replacing it as best as possible, it's still leaking slowly. Not going to pull them out; the leak isn't that large that they can't be used by topping them up each day I'm towing but I may want an additional solution.

Anyone have experience with Timbren or Sumo Spring bumps for towing?

happy birthday!

Thanks Wes!
