2wd transmission in 4wd

[CrazyW]

Can a 2wd 4L80E be adapted to work in place of a 4L60E in a 4wd truck/SUV like the 2wd th350 can be used in place of a 700R4 in a 4wd? I have done the 350/700r4 swap before but I have little knowledge of the newer transmission specs as far as output shaft length etc. I do know that the 80E has a bigger output shaft diameter than the 60E but I also have a t-case that came factory behind a 4L80E. Just don't have the 4wd transmission to compare. Any insight is appreciated and thanks in advance.

2wd trans won't bolt up to a transfer case will it?

When using a 2wd short shaft th350 to replace a 700r4, there is an adapter plate that goes on tailshaft housing and then the 2wd transmission will bolt to transfer case...my question is whether or not they make an adapter plate to use a 2wd 4L80E in a 4wd truck

I think you need to talk to a tranny shop.

you will need to...

then THIS

then: add the transfer case and shift hardware and software.

the modify the drive line...

For myself, I would just buy a truck that has the OE stuff I want to run with. With computer controlled trans and electronic transfer case gear selector, it gets complicated.
