Hello all,
I have a few 4l80e's and need to know how to ID the year or which one I should use. Two were pulled and have GM reman stickers on them. but one is a 4x4. I also have one I did pull from a '05 2500 4x4 but it has a modual on the side of it.

I have a transgo stage 3 full manual valebody for one but not sure which one to use.

Also the 2wd has a bolted on yoke. How or what do i change to get it to work with a slip yoke.

Thanks for the info
