I can't help you with that. 4x4 6L80 have 32 spline outputs

4x4 4L60 is 27

4x4 6L90 is a big boi 29

Im using a 241 from behind a manual GMT400, and a 6L80: so I know my combo is good to go

 

So in theory. This should solve my 6L80 to 3023NQH issue.

I am no expert. I know the NP/NV cases a lot more than I know any of the Borgs, and even then.... I only know enough to get in trouble

Looks good from here tho. Going from 65e to 80e means you need swap from 27 to 32 spline. You do not need the 29, but keep in mind the 29 spline is like 2.5" in diameter. It's massive. Classic case of spline count =/= OD

 

Some information is best bounced off the masses to check for enthusiasm errors.

In my case I have a 4x4 6L80 so that would be the 32 spline. Meaning. I should be able to swap to a t-case input gear with 32. Which I believe is out of a Hybrid truck technically (at least based on my short amount of time researching. We will be upgrading the internals to 90e to include the extra clutch packs and likely the heavy duty baskets. But the output will remain at 32 spline.

FWIW I Just bought this 07NBS truck in Nov 2021 as a replacement for my K2xx Denali. Immediately started a laundry list of mods. Been a few years since I have been in a GMT900. Having to re-learn and remember a lot.

 

Wait so you have an NBS or a GMT-900 I am confused cx

 

07NBS is GMT900 https://en.wikipedia.org/wiki/GMT900
-vs-
07 classic is GMT800 https://en.wikipedia.org/wiki/GMT800

 

07 is NNBS cmon man we just did this thread!

Ah tomato tomató.

I speak in terms of platform.

Didn’t I read above your truck is broke…. I rest my case. J/k 😘

 

**** all you guys!

 

@banks53 I think we are saying the same thing about the splines. Your input gear can come from any 4x4 6L80, not just hybrid trucks
