80 swap with autotrac trans-case
Ok I have looked and maybe over looked, but I have a few questions on my 4l80 swap. My truck is a 2003 Single cab short bed 4wd with the autotrac T-case.
1.what input shaft do I need to use my stock T-case?
2. Does any one have the front and rear drive shaft lengths?
3.will the 80 T-case adapter work with the autotrac?

32 spline input shaft Part number 19019 for transfer case.
HD truck front driveshaft.
If you don't have a 4wd trans you need this adapter:
4WD 5'' trans output shaft. 91-96 need the oil hole. Newer can't have it.
1 13/16 shorter rear driveshaft.
Modified cross member moving trans mounting point back 2.5 inches.
Please search for other threads. There is a ton of info out there.

Thank you for the info, I'm familiar with the swap just have never done one with a autotrac T-case. That was my question if the Autotrac requires anything diffrent from the other cases, iv been told it needs a diffrent input shaft.

I'm learning all this along the way to my eventual swap. I still need to finish my trans rebuild. Also, Atomic provided a ton of good info
Perhaps you'll be able to answer my trans/tuning questions in the future!

I have done the swap.
like mentioned you will need a 32 spline input shaft for the tcase along with the tail housing adaptor.
my local trans shop had both of the items in stock and cheap
