Transfer case info
Still gatherin parts for my 4l80e swap in the 2003 z71 tahoe.
Right now it has the NP246 GM auto trak.
I havent had any dealings with transfer cases except the NP241 i did in the Samurai.
So here is my question....
Can i use a non autotrak?
Or is there something funny about the automatic 4wd?

I believe only the NP246 is the electronic unit while the other's are manually engaged. There may have been a BW unit in the later years like 07 up but I am not sure on those.

You can get a 32 spine input gear for the case you already have for about $150 IIRC.

Depending on the year and the Code there was NV243C, NV246C, NV263C
I believe the C at the end is specific to the GM brand as some of these were used in other brands like dodge and the jeep line up.
I believe the electronic RPO codes for GM were NP1 and NP8
NP1 was NV243 in 96-00
NP1 was NV263 in 01-06
NP8 was NV246 in 99-06
These were also available in both 27 spline for the 4L60E and 32 spline for the 4L80E using the same code.
This is the info I found online through various site's and dismantlers. So don't shoot me if i'm wrong.

Yea the 241 come out of a older straight axle suburban that was passenger side drop. So it worked perfect in the sami. And manual shift.
Just wonderim was there any difference if i got a non autotrak xcase like the 263. Would the push buttom still engauge hi , and 4 lo?
