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.

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.
